Design for Virtuosity: Modelling and Supporting Expertise in Digital Musical Interaction

Lead Research Organisation: Queen Mary University of London
Department Name: Sch of Electronic Eng & Computer Science

Abstract

Musical performers spend many years achieving proficiency on their instruments. Newly-created digital musical instruments (DMIs) face a significant barrier to adoption in that few performers are willing to repeat these years of training to develop expertise on an unknown instrument. Without expert players, evaluating the success of a DMI design is challenging, and establishing its place in a broader musical community is nearly impossible. As a result, while many digital instruments have been created over the past decade, few have achieved lasting impact beyond the first few performances.

This fellowship proposes a new approach to DMI design which repurposes the existing skills and experience of trained musicians, providing them with a rapid path to virtuosity without years of retraining. The research programme is organised around two complementary themes: study of performer-instrument interaction and creation of new instruments which capture the full richness and subtlety of virtuosic performance.

First, models will be developed of the interaction between performer and instrument. Instrumental performance can be considered a special case of human-machine interaction which is interesting both for its complexity and for the common experience that the musical instrument becomes an extension of the body: while playing, the performer is often not consciously thinking about the instrument. Controlled experiments and participatory design exercises will establish how an instrument's design affects the development of expertise, and how existing expertise can be transferred to newly-created instruments.

Second, the resulting models will be applied to the DMI creation process, taking a holistic approach unifying hardware design, digital signal processing, human-computer interaction (HCI) and artistic considerations. Existing DMIs often implicitly prioritise the convenience of the computer over the experience of the human player. On acoustic instruments, the entire physical object contributes to the sound, however subtly, but the choice of sensors in a DMI typically reduces the performer's actions to just a few machine-tractable dimensions. This fellowship will create instruments which deliberately oversample the interaction, using more sensors and higher sampling rates than apparently necessary, not to create a more complicated instrument, but rather to capture the subtle nuances that experts prize. Evaluation of the new DMIs will help refine the original models of performer-instrument interaction.

This project focuses on musical interaction, but the principle of repurposing expertise is widely applicable within HCI. The capabilities of human users cannot be modelled only through generic cognitive and motor processes; real people have specialist skills developed over years of practice, and new technologies which connect to those skills are far more likely to find acceptance than ones which must be learned from scratch. Music is a good test case since instrumental training is widespread and reasonably standardised, but the findings will be relevant to other expert domains.

This fellowship supports the time of the PI and two postdoctoral researchers. One postdoc will focus on performer studies and interaction, the other on digital signal processing and data mapping strategies. Close collaboration with musicians throughout the research will ensure its relevance to that community. This research integrates hardware design, digital signal processing, human-computer interaction, cognitive science, musicology and arts practice. The PI, with background and professional activities in music composition, electronic engineering and HCI, is ideally placed to lead this multidisciplinary project.

Planned Impact

This fellowship holds benefits for a wide variety of groups beyond academic researchers, both in the UK and internationally:

Industry:

* Musical instrument manufacturers, who will benefit from new tools and approaches to instrument design. Selling the same instruments year-upon-year risks market saturation, but conversely, uptake of unfamiliar instruments is a challenge for the industry owing to long learning curves. This fellowship will demonstrate how to create instruments which are creatively distinct from previous designs but still connect to existing skills.
* The broader technology industry, through creation and sales of computer interfaces which integrate into a user's existing workflows.
* Concert venues and promoters, who will benefit from performances involving new creative digital tools.
* Electronics companies serving the open-source and maker communities, who can develop and sell tools based on the open-source hardware released during this project. Open-source hardware makes the designs available freely to all, but it is also an important economic engine, as evidenced by successful companies like Arduino in Italy and SparkFun and Adafruit in the United States. This project will support the UK's growing role as a driver of the open hardware movement.

Musicians:

* Professional performers, who will benefit from instruments which connect to their existing training. By reducing relearning, instruments on the fellowship will make better use of their time, which holds a direct economic benefit.
* Composers, who will benefit in two ways: from immediate opportunities to write for new instruments during the fellowship, and from continuing opportunities when new instruments become established in the musical community.
* Instrumental teachers and students, for whom a deeper understanding of performer-instrument interaction will be relevant to teaching the subtle details of performance technique.
* Disabled and special-needs musicians, who will benefit from instruments which make more effective use of their abilities (with assistance from project partner The One-Handed Musical Instrument Trust).

Schools and Third Sector:

* School music teachers, who can use new digital instruments to promote student interest in music learning.
* Science and technology teachers, who already use the CS4Fn/EE4Fn (Computer Science for Fun; Electronic Engineering for Fun) project at QMUL to promote student interest in computing/engineering careers. This fellowship will contribute new articles and activities on digital musical instruments to the project and assist with the project's dissemination into schools.
* Independent groups promoting STEM (Science/Technology/Engineering/Maths) education, who can use digital musical instruments as the basis of workshop and outreach activities for students.
* Charities promoting music accessibility, for whom the workshop organised by partner OHMI can serve as a model, and for whom the technologies developed on the fellowship can later be applied to create accessible musical interfaces.

Wider Public:

* Amateur musicians, who will benefit from new instruments which make effective use of their training time.
* Audiences, who will benefit from engaging digital musical instrument performances where the expertise of the performer is clearly evident.
* Electronics hobbyists, who can use the open-source tools created on this project; these tools will be designed to use commonly-available fabrication techniques such as 3D printing to make them more accessible.

In addition to the fellowship's primary research activities, a targeted programme of workshops, concerts, recordings, artist residencies, schools talks, industry events and release of open-source designs will ensure the fellowship reaches the beneficiaries named above.

Description In the first year of the fellowship, the preliminary findings divided into two categories: the influence of musical instrument design on the performer experience, and the ways that technical tools influence the actions and experience of the designer.

In the first category, we have conducted studies with violinists to understand how modifying the violin affects the existing expertise of the performer. We have found that violinists can easily adapt to small changes in the instrument, but that certain changes, such as reversing the order of the strings, result in a nearly complete inability to play fluently. This simple experiment demonstrates the importance of highly developed sensorimotor processes on musical performance. This led to publications in the journal Frontiers in Psychology and the New Interfaces for Musical Expression conference.

We are also investigating how to develop new instruments which make use of established sensorimotor skills, a topic which began in the second year of the grant and will remain ongoing through its conclusion.

There are several lines of enquiry in this project. One looks at modelling, parameterising and ultimately extending the signals generated in traditional musical instruments. Over the past three years we have developed new sensing hardware and a real-time signal model of the string vibrations of the acoustic violin which has a more nuanced representation than current industry standard music data protocols like MIDI, while also containing a richer understanding of the acoustics of the instrument a typical audio signal. We also conducted early experiments using deep learning techniques to parametrise bowed string signals in real time.

A second line of enquiry has focused on instrument accessories which address questions of expert playing technique. We developed a new control device for electric guitar: the Magpick, a plectrum which senses the ambient magnetic fields around the pickups and allows the performer to manipulate the sound of the guitar through subtle hand motions over the strings which are easily learned and compatible with existing technique. This work has led to an ongoing collaboration with the University of Auckland.

A third line of enquiry looks at acoustic actuation of instruments. Performers often emphasise the importance of an instrument that produces its own acoustic sound locally to the performer, as opposed to electronic instruments whose sound is exclusively produced through external speakers. We have developed a new hybrid acoustic-electronic violin where the strings and bridge are acoustically isolated from the body, and the body is instead driven by electronic actuators. This allows transformations of the sound to be applied between performer and acoustic output. In this area of enquiry, we also continue to develop the possibilities of actuation of acoustic piano strings, working closely with performers and composers to understand both sensorimotor and cultural implications of new instrument technologies.

We have also conducted experiments with percussion instruments, showing how latency and the constraints of an instrument change the gestures that performers choose to interact with the instrument. Our results suggest that the relationship between the performer and instrument goes both ways: not only does the performer control the instrument, the instrument design implicitly influences what actions the performer chooses to take.

A final line of enquiry take a broad view of recent work in digital musical instrument design, both within academic communities (e.g. the conference New Interfaces for Musical Expression) and within industry (especially crowdfunding campaigns). We have identified common traits of successful instruments which are still being used and made recommendations for designers in papers published or submitted at conferences in the field. This has led to several collaborations in various stages of the pipeline, producing joint papers and workshop proposals on what factors promote instrument or how the tools designers use affect their creative choices. This work has led to wide-ranging discussions in our core research community about how best to archive and distribute knowledge about new instruments.

In the category of how tools influence the designer, we have studied how open source tools can be used to support musical instrument design, and we have investigated the process by which communities form around tools. For this work, we used the Bela audio platform developed in our lab (which has been significantly enhanced and expanded since the beginning 2016). A paper on open source community building was published at CHI 2017, with a further paper at a CHI 2017 "HCI tools" workshop. We regularly host public and academic workshops on these topics, and we also host regular external visitors of durations from a few days to several months. In 2019 returned to CHI for a workshop on research through design, showing some of our recent tools and instrument technologies and examining their implications for a wider HCI community.
Exploitation Route This work has academic, commercial and cultural implications. In terms of core research, the project has opened up interesting questions around sensorimotor skill and its transfer from one domain to the other. One area of enquiry that might be productively explored in future research is "auditory imagery", or the mental imagination of sound without actually hearing it. Our research has suggested that auditory imagery plays an important role in instrumental performance, and that the successful transfer of expertise between instruments may be dependent on coherent auditory and motor imagery. This work may be of interest to psychology and human-computer interaction researchers.

The research on new sensor and actuator technologies for musical instruments will also be of interest to several communities. Already we are seeing uptake of our research amongst a set of collaborators in our core research community: for example, a string instrument sensor technology we published at the NIME 2019 conference is being used by other researchers and artists. Beyond the musical domain, some of these technologies could also be used more widely in human-computer interaction research; one PhD project outside the project has used them to study the working processes of skilled craftspeople through augmented sonic an haptic feedback.

The sensor and actuator technologies also have commercial potential. Already a capacitive touch sensor technology first created in an earlier research project but further developed on this project has been licensed to QMUL spinout company Augmented Instruments Ltd, where it was the subject of a successful Kickstarter crowdfunding campaign. Aside from the commercial implications, these sensors will enable makers and artists to easily create sophisticated interfaces they would not have otherwise been able to make. We also expect that complete instruments developed on this project may have commercial potential. One instrument, a hybrid acoustic-electronic violin, won third place in the annual Guthman Musical Instrument Competition at Georgia Tech. While commercial readiness might take several years, if successful the commercialisation could deliver both economic and cultural impacts.

Finally, the instruments and technologies we have developed on the project are finding increasing use amongst composers and performers. We have observed that devices that begin as focused research probes end up finding rich and varied use in the wild. Sometimes this can be a complete instrument, or other times it may be a technology that is adopted by instrument designers outside the research domain. The pandemic and consequent lockdowns led to a delays in the parts of the project engaging with performers, but we have picked up some of these activities as performance events have become possible again, with future activities still planned.

This project began with a focus mainly around sensorimotor skill in musical performance, and from this initial focus, several other interrelated areas emerged which can be taken forward in future research. One is around the creation of hardware and software systems with sufficient bandwidth of interaction, and sufficiently low latency, to capture and process the rich and nuanced physical language of musical performance. The need for high-performance embedded hardware was already clear going into the project, but several years of research revealed specific directions which are still in need of further investigation, especially around increasing the total amount of sensor data captured and finding ways of intelligently processing that data. The other stream of research to be taken forward concerns the cultural and aesthetic values which are embedded into every technology. Future research could seek a more transparent account of these values and how they influence designers.

Description Commercial: In 2016, we spun out a company Augmented Instruments Ltd to commercialise work coming out of my laboratory. Its flagship project is Bela, an open-source embedded hardware platform for creating musical instruments and other interactive systems, which is targeted at makers and artists who may not have a formal engineering background. Sales of Bela exceed £500k since its launch, and the company also receives income from several commercial consultancies. In 2018-19 the company led a £70k grant from Innovate UK on reaching new communities with interactive technology. In 2019, a capacitive touch sensor technology developed in our research was launched by Augmented Instruments Ltd in a Kickstarter crowdfunding campaign. Trill, as the sensor is know, raised over £25k on the campaign, and attracted significant interest from makers and artists worldwide. The company continues to grow organically and steadily through sales and consultancy. Artistic: my lab has hosted over 15 musical performance events since the start of the fellowship. These events have featured new instruments developed on the project alongside instruments developed by PhD students I supervise. Several performances have had invited external guest artists. A pre- and post-lockdown concert series at the Iklectik Art Lab in south London has been routinely sold out (capacity ca. 100), and these concerts have led to publicity in the Guardian and other media. Streaming concerts were held during the Covid lockdowns. Beyond that, the instruments created in my research have been adopted by a growing community of composers and performers. The magnetic resonator piano, an augmented acoustic piano that uses electromagnets to actuate the strings, has been performed dozens of times over the past 5 years. Pianist-composer Xenia Pestova Bennett has engaged in an extended project with the instrument that has included a commercial album released on Diatribe Records, performances in Germany, Ireland and the UK, and featured segments on BBC Radio 3. The instrument has also been used in a major motion picture film score (released 2018), two operas (2018-20), and jazz and chamber music albums released in 2020. An augmented violin created on the project in 2019 has been performed in several concerts and won third place in the Guthman Musical Instrument Competition at Georgia Tech (March 2020). An optical keyboard scanner developed on the project is now in regular use by several composers and pianists. Charity: We are increasingly working with third-sector organisations on public engagement, including the OHMI Trust, a charity dedicated to accessible music-making. The partnership with OHMI predates the award but has significantly strengthened in the past year to include several new activities including the organisation of a conference on "Music and Physical Disability" which took place in September 2018. QMUL has become a founding member of the OHMI Research Partnership (ORP), a collaborative effort to maintain an active research base on musical instruments for the physically disabled. I became a trustee of OHMI in 2021. We have also worked closely with the charity Heart n Soul, which provides community activities for children and adults with learning disabilities. This work is also supported by the EPSRC and AHRC CDT in Media and Arts Technology. PhD students in the lab have created new guitar-like instruments which were initially used to investigate research questions around sensorimotor skill and cultural form, but which have subsequently found regular use in Heart n Soul's musical activities for their community. We have worked with dozens of learning-disabled people and several facilitators. Following on from this, in 2019-2020, we have had a small research project funded by the Chelsea and Westminster Hospital Foundation (CW+) on the design of new instruments for stroke patients in a recovery ward. An initial design is now being tested with patients and clinicians. Other parters include the music charities Heart n Soul and Drake Music, the community interest company Conductive Music, and larger companies like Ableton (Berlin, Germany) in whose Loop Festival we have participated in in 2017, 2018. Ableton has gone on to fund further research in my lab on accessible music technology, considering use of music production software by visually impaired musicians. Other public engagement: We regularly host workshops and exhibitions on technology from the lab. The Bela embedded platform is often a focus of these events, which range from science fairs aimed at teens to industry-targeted technical workshops. I have given talks aimed at the general public at venues ranging from the IET to the Ars Electronica festival. We have also hosted artistic residencies by several composers, performers and designers, providing new interactive technologies for them to use in their projects and often co-organising performances or exhibitions.

PI Contribution This collaboration with Prof. Dan Overholt at Aalborg University Copenhagen explores electronic augmentation of the violin for teaching and performance purposes. This relates closely to the theme of our research on skills transfer and designing for expertise. A postdoc, Laurel Pardue, worked 50% time at QMUL and 50% time at Aalborg funded by an internal grant from that university.
Collaborator Contribution Aalborg University funded an 18-month 50% FTE postdoc position through its "International post-doc" funding scheme. The postdoc, Laurel Pardue, worked the other 50% time at QMUL. She was supervised at Aalborg by Prof. Dan Overholt. The broader context of this project is a collaboration between our research lab and the Nordic Culture Fund project "Acoustically Active Augmented Instruments" (AAAI), which brings together researchers from Norway, Finland, Denmark and Iceland. This project has also funded a visit by our team to the University of Oslo to deliver a workshop.

Country United Kingdom 
Sector Academic/University 
PI Contribution I have collaborated with members of the Mixed Reality Laboratory (led by Steve Benford) in Nottingham's computer science department on studies involving the D-Box hackable musical instrument. We have co-organised a series of free public workshops where people hack the D-Box instrument. I lead the workshop activities while the MRL researchers collect interviews and video footage as the event goes along, which we use for later analysis. Subsequently, we worked with MRL on a workshop at the STEIM electro-acoustic music centre in Amsterdam, using the Bela audio platform created in our lab. We led the technical aspects of the workshop, while MRL contributed to ethnographic study of how people used the technology. A paper on the results was accepted to CHI 2017. In 2019 we began preparing an ethnographic study of digital musical instruments in a community of learning-disabled individuals. Our team provided the instrument technology and the background in music and disability studies, while MRL contributed expertise in HCI and ethnography. This led to a late-breaking work paper at CHI 2019 and my participation in a CHI 2019 paper led by the University of Nottingham. In January-March 2020, I hosted PhD student Juan Martinez Avila, who has been working on augmented guitar research, and collaborated on a workshop on somaesthetic design of musical instruments. This led to a paper at the New Interfaces for Musical Expression 2020 conference ("Soma Design for NIME").
Collaborator Contribution MRL contributed their Artcodes research to the project. Artcodes are a form of information encoding in images based on patterns of open and closed shapes; notably, nearly any physical design can be turned into an artcode through careful management of light and dark regions. Artcodes are useful for linking physical objects to their virtual records in an aesthetically elegant manner. MRL also led the data collection and transcription for the workshops. We jointly prepared papers on the results. In 2019, MRL led work on studying the practice habits of musicians for a paper on which I am a co-author, and has contributed expertise on somaesthetic design and ethnography which has informed our joint work.

Description OHMI 
Organisation One-Handed Musical Instrument Trust
Country United Kingdom 
Sector Charity/Non Profit 
PI Contribution We have contributed to the design of new musical interfaces accessible to musicians who lack the use of a hand or arm, following OHMI's core mission to enable "full and undifferentiated participation" in musical performance. I continue to serve as a judge on the annual One-Handed Musical Instrument competition and presented at the Ars Electronica festival where their awards were held in 2014. In 2018 I was one of the paper chairs for the conference Music & Physical Disability: From Instrument to Performance (Birmingham, UK, September 2018). Since that time I have been involved in discussions for creating a new OHMI Research Partnership to develop original research and translational activities to increase the accessibility of musical performance to people with physical impairments. I continue to advise OHMI on new technologies for accessible music performance.
Collaborator Contribution OHMI has provided guidance on design principles, access to professional instrument builders and feedback from teachers and students. They have provided financial support for ordering parts for PhD student projects. Each year OHMI hosts a PhD student on the EPSRC and AHRC Centre for Doctoral Training in Media and Arts Technology. I am the academic supervisor for those placement projects. OHMI is a partner on my EPSRC Fellowship (EP/N005112/1), providing expertise on performance and education, and connections to instrument makers and other practitioners in the field of music and disability.
Impact As a result of earlier collaborations, OHMI is now a project partner on my EPSRC Early Career Fellowship. The collaboration is multi-disciplinary: OHMI is primarily an arts and cultural organisation which also contributes to policy on music education for the disabled (e.g. through a 2017 House of Lords event hosted by the Lord Lipsey). This collaboration crosses from these areas over to science and engineering. Other outcomes include: several awards from OHMI for student projects I supervise, including Duncan Menzies (one-handed bagpipe chanter, 2017); Jacob Harrison (adapted bass, 2017). Duncan's chanter has gone on to be featured on BBC and Radio Scotland. In September 2018, I helped organise a conference Music & Physical Disability: from Instrument to Performance, contributing on the academic programme. OHMI acted as central organisers of the conference, with further assistance from researchers at Birmingham City University. The conference brought together researchers, teachers, artists, musical instrument makers and industrial partners from around the world to start an important conversation around the creation of accessible instruments for musicians with physical disabilities.

With less than 1ms of latency between action and sound, Bela performs faster than any other computer-based environment on the market, including high-spec laptops. It also features audio-rate sampling of every analog and digital input which makes design of sensor systems convenient. In 2015, a built-in browser-based IDE was added along with support for the Pure Data graphical computer music language widely used in the digital music community. Since 2016, we have continued to add support for other programming languages and hardware accessories, as well as extending the documentation and online resources available to the community. 
Type Of Technology Software 
Year Produced 2014 
Open Source License? Yes  
Impact Bela has gained significant traction amongst researchers, musicians and hobbyists in the 2014-17 period, with the number of users and community members growing every month. On 29 February 2016, we launched a Kickstarter crowdfunding campaign for Bela, seeking £5k to build and distribute the hardware. We exceeded our funding goal in less than 4 hours (out of a 32-day campaign), ultimately raising £55k from over 500 backers. Following the campaign, we received invitations to collaborate from major academic institutions (IRCAM in France, STEIM in the Netherlands, University of Virginia, University of Edinburgh, University of Glasgow, Goldsmiths University and several others) and industry (Cycling74, makers of the popular Max/MSP software). Meanwhile, since 2014 we have held 10+ workshops on Bela and/or the D-Box instrument including 2 workshops at the Sonar music festival, a workshop at the NIME 2015 conference (Baton Rouge, LA, USA), an Audio Music Hackathon sponsored by Harman Audio, and an Accessible Music Hackathon with the charity Drake Music (held at QMUL). Following the successful Kickstarter campaign, we spun out a new company, Augmented Instruments Ltd, to commercialise the platform, and relaunched a public web shop in October 2016. We maintain several community resources, including a blog, wiki, web forum and several social media accounts. Our users actively contribute to these resources and frequently share projects they make using Bela. Community development itself has become an area of research for us (e.g. Morreale et al., "Building a maker community around an open hardware platform", Proc. CHI 2017), and we have received a grant from Innovate UK (Feb-Oct 2017) to further develop the platform and build our community.

Title Trill touch sensors 
Description In 2014, as part of the EPSRC project Hackable Instruments (EP/K032046/1), I created a new capacitive touch sensor as part of a musical instrument called the D-Box. The sensor measured the position of up to 5 fingers along a single linear axis. Later, on the Design for Virtuosity project (EP/N005112/1), I and others in my lab further developed the touch sensor technology, using it in other instruments and producing expanded designs that sensed in two axes. In 2019, as part of an Innovate UK funded project in collaboration with QMUL spinout Augmented Instruments Ltd, this technology was developed to the point of commercial readiness. While capacitive touch position sensing is commonly found in consumer devices, the design of these sensors has often been limited to just a few experts. By contrast, these touch sensors are designed to be easy to use for makers, artists and researchers who are not expert embedded engineers. Accordingly, a set of libraries and example materials for popular maker platforms such as Arduino and Bela were developed. 
Type Of Technology New/Improved Technique/Technology 
Year Produced 2019 
Impact The technology has been licensed to QMUL spinout Augmented Instruments Ltd, which also commercialises the Bela embedded platform which has come out of my research. The touch sensors have been branded "Trill" and are available in five formats: Bar (a one-axis slider), Square (a two-axis touch pad), Hex (two-axis tileable hexagons), Ring (a circular slider) and Craft (individual pins exposed for designers to make their own interfaces). The company ran a successful Kickstarter campaign in September 2019, raising £25k toward the production of Trill sensors. Shipping commenced in April 2020 and sales have continued at a steady pace since then. In March 2021, the company introduced Trill Flex, based on a flexible PCB design I co-created during the time of the Kickstarter campaign. In January 2023, the company launched Gliss, a synthesiser module featuring the Trill technology, raising over $70k on the crowdfunding site Crowd Supply.

Company Name Augmented Instruments Ltd 
Description Augmented Instruments Ltd is a spinout from the Centre for Digital Music at Queen Mary University of London, incorporated on 8 September 2016. The aim of the company is to develop and commercialise digital musical instrument research developed in the Augmented Instruments Laboratory, a research team within the Centre for Digital Music led by Dr Andrew McPherson. Technology is licensed from QMUL to Augmented Instruments Ltd, which develops and sells direct to consumers and conducts business consultancy related to the technologies. The company's flagship product is Bela (http://bela.io), an open-source embedded computing platform for ultra-low-latency processing of audio and sensor data. Bela, originally known as BeagleRT, was developed starting in 2014 in the Augmented Instruments Laboratory. Since its creation for a specific musical instrument, it has gradually grown into a general-purpose platform aimed at the maker and musician communities. It couples high performance (1GHz processor, submillisecond latency, high-bandwidth, synchronous gathering of audio and sensor data) with ease of use (a browser-based development environment and support for popular computer music programming languages). On 1 April 2016, Bela completed a highly successful Kickstarter campaign which raised £54,902 (out of an original goal of £5k). This provided the seed funding to spin out the company, which has subsequently been supported by sales of Bela and industrial consultancy. 
Year Established 2016 
Impact Augmented Instruments Ltd launched Bela for public sale in October 2016. Its annual turnover was around £200k in 2021. The company is profitable without the need for investment funding. As of early 2022, it employed two full-time staffs member and several part-time positions. Income came from sales and from several industrial consultancy projects. In the second year, the secure two grants from Innovate UK. It launched a new product, Bela Mini, in February 2018. It also continued to support a growing open-source community, providing resources including a repository of code and hardware designs, a tech support wiki, an online discussion forum, a blog featuring user-created projects, a YouTube channel and other social media links. As of early 2022, these resources continue to grow in scope and audience. We estimate that 3000+ unique users on 6 continents have acquired their own Bela boards since the project began. Bela sales to date exceed £600k. We studied the characteristics of our early adopter community in [3.1]. It contains a diversity of profiles and interests: makers (i.e. technology hobbyists and independent creators); musical performers; musical instrument and synthesiser designers; interactive artists; teachers; students; researchers in fields ranging from human-computer interaction to digital signal processing to neuroscience. As of early 2019, AIL also had around 200 institutional customers, including universities (45%), companies ranging from SMEs to large multinationals (25%), design and art consultancies (17%) and arts/maker organisations (6%). Bela is being used for teaching in 20 universities beyond QMUL including Aalborg University Copenhagen (Denmark), University of Kiel (Germany), University of Virginia (USA), Griffith University (Australia) and NTNU (Norway). Since 2016, Bela has been used in dozens of public workshops across Europe, North America and Australia, including events at maker spaces, museums, trade shows, music festivals, conferences, universities, secondary schools, and many other public venues. Many of these were led by the Bela creators (first at QMUL, then also at Augmented Instrumenst Ltd), and some are led spontaneously by our community. Total participation across all events is hard to precisely quantify, but is easily in excess of 1500 people. Bela maintains a committed and enthusiastic online community who contribute back to the project through porting software tools (e.g. computer music languages SuperCollider, Csound, FAUST, pyo) and through writing up and sharing projects built with Bela. In 2019, the company completed another successful Kickstarter campaign for Trill, a new type of capacitive touch sensor aimed at makers and artists. The campaign raised £25k and sales have continued since then. In January 2023, the company launched Gliss, a synthesiser module featuring the Trill technology, raising over $70k on the crowdfunding site Crowd Supply. As of 2023, the company continues to grow steadily based on sales of Bela and Trill products and industrial consultancy services, and the Bela community continues to expand in industry, education, research and creative practice.

Primary Audience Professional Practitioners
Results and Impact On 8-9 November 2019, our lab hosted "Unuseless Music Designs: A Seriously Absurd Hackathon". This two-day event was led by QMUL PhD student Giacomo Lepri with support from other members of my lab. A call for participants led to applicants from three continents (Europe, N. America, S. America) and about 30 participants. The two-day event included talks from invited mentors John Bowers (Professor of Creative Practice at Newcastle University) and Hannah Perner-Wilson (a leading practitioner of e-textiles based in Berlin) plus short introductory workshops on e-textiles and the Bela embedded audio/sensor platform.

The main part of the event was the open development of absurd new musical interfaces, which also served a serious purpose as an investigation and critique of the values found in the musical instrument community. The event concluded with short presentations from each of the designers which were videoed and shared online. Participants expressed interest in developing their ideas further following the event, and discussions began about hosting a second similar event in the near future. One immediate outcome was the submission of a workshop proposal to the New Interfaces for Musical Expression 2020 conference, which was accepted and subsequently won the best workshop award.

The paper sensor activity was developed by Becky Stewart as part of an Innovate UK grant led by Augmented Instruments Ltd, a spinout company from my research. Compared to traditional electronic assembly using breadboards or printed circuit boards, paper and copper tape can make circuits much more rapidly, building on skills that most people already have. It is therefore an ideal medium to introduce electronic making to broader audiences.

Results and Impact In August 2016, my research lab organised a 3-day hands-on instrument design workshop at the Studio for Electro-Instrumental Music (STEIM) in Amsterdam. The workshop featured Bela, an open-source embedded platform for ultra-low-latency audio and sensor processing, which was developed originally as part of the EPSRC-funded Hackable Instruments project.

The workshop had 8 participants who were digital musical instrument designers, plus several other people attending as observers. The event was facilitated by two technical organisers and two other researchers. The instrument designers each brought an existing instrument design which they ported to Bela with the help of the organisers. We recorded audio and video from the session, including regular interviews with each participant. This event led to a paper in CHI 2017 (Denver, USA) on community formation around open-source hardware tools. It also led to several participants using Bela in their own music and art installations at a wider scale.

Results and Impact On 4-5 December 2015 we held two tutorial workshops on the Bela low-latency audio platform. These were free and open to the public. Originally the plan was to hold a single event, but high demand resulted in it filling up quickly, so we scheduled a second one the day before. In all we estimate the attendance at 40-50 people. Feedback was positive and many people bought hardware from us to continue using Bela in their own projects. This event was one of several that laid the groundwork for our highly successful Kickstarter crowdfunding campaign in March 2016.

Since the original workshop, we have held several additional workshops throughout 2016 and 2017, together reaching several hundred people. Events have taken place in London, Glasgow, Edinburgh, Brighton, Berlin, Toronto, Baton Rouge and Brisbane, among others. Some events have targeted hobbyists and makers; others have targeted musicians and industry professionals; still others have targeted undergraduate and postgraduate students. Collectively, these events have significantly expanded the profile of the Bela platform, leading to research collaborations, increased public profile of our work and commercial benefits (hardware sales through a spinout company).

Primary Audience Industry/Business
Results and Impact C4DM presented a public exhibition of its research at the Sonar+D 2016 festival in Barcelona, 16-18 June 2016. Sonar+D is a high-profile annual exhibition of music technology attended by thousands of industry professionals, musicians and members of the general public. C4DM was chosen by competitive application for a booth on the exhibition floor. We showed 9 recent research projects supported by EPSRC funding (EP/K009559/1, EP/K032046/1, EP/G03723X/1). The booth attracted significant interest from a broad cross-section of the Sonar audience: it was nearly full for most of the three days, and anecdotally appeared to have more traffic than most of the booths at the exhibition. In parallel with this in-person exhibition, Sonar+D featured C4DM in their social media feeds, and we were interviewed for a broadcast on Spanish television. Aside from public engagement, the exhibition led to several new industry contacts, and it provided valuable feedback to the attending PhD students and postdocs on how to showcase their research in public.

The projects shown were:

1) Bela, an open-source platform for ultra-low-latency audio and sensor processing, which launched on Kickstarter in 2016;
2) TouchKeys, a transformation of the piano-style keyboard into an expressive multi-touch control surface, launched on Kickstarter in 2013 and spun out into a company in 2016;
3) Collidoscope, a collaborative audio-visual musical instrument which was a viral hit online with over 10M views;
4) RTSFX (Real-Time Sound Effects), an online library of real-time synthesised (rather than sampled) sound effects for a variety of different objects and environmental sounds;
5) Moodplay, a mobile phone-based system that allows users to collectively control music and lighting effects to express desired emotions;
6) Augmented Violin, a sensor-based extension of the traditional violin to give students constructive feedback on their playing
7) Tape.pm, an interactive object which explores novel ways to record and share an improvisation that is created on a musical instrument;
8) Aural Character of Places, an interactive online demo of soundwalks conducted around London;
9) MixRights, a demo of how content reuse is enabled by emerging MPEG standards, such as IM AF format for interactive music apps and MVCO ontology for IP rights tracking, driving a shift of power in the music value chain.

Several potential collaborations may result from this visit, including commercial opportunities related to the TouchKeys and Bela projects, and possible joint projects with other university labs who attended (e.g. IRCAM and the Music Technology Group at Universitat Pompeu Fabra in Barcelona). The publicity surrounding this exhibition may also serve as a recruitment tool for future research students in the Music and Acoustic Technology research area.

A particularly valuable outcome, especially for the PhD student attendees, was experience in showcasing their research to the public. Several students commented that they received valuable feedback on their projects and learned general skills in public engagement over the course of the three days. In one case (Tape.pm), interactions with the public helped generate a dataset which will be analysed in future research.

Finally, attendees at Sonar+D also had the opportunity to see other booths and talks at the event, generating new ideas and connections for future projects.
