While there are a great variety of digital musical interfaces
available to the working musician, few offer the level of immediate,
nuanced and instinctive control that one finds in
an acoustic shaker.
bEADS is a prototype of a digital musical instrument
that utilises the gestural vocabulary associated with shaken
idiophones and expands on the techniques and sonic possibilities
associated with them.
By using a bespoke physically informed synthesis engine,
in conjunction with accelerometer and pressure sensor data,
an actuated handheld instrument has been built that allows
for quickly switching between widely differing percussive
sound textures. The prototype has been evaluated by three
experts with different levels of involvement in professional

This piece was designed to re-frame popular conceptions of technology. By creating a computer mediated artefact that makes people more aware of their immediate surroundings, and the people in it, we aim to make people think about interaction on many levels.

I’m proud to be appearing at the Guthman Competetion in Atlanta this year. From commercial products to imaginative stringed instruments to a contraption that allows a fetus to make music, this year’s competition pushes the boundaries of soundscapes and musical design.
I will be playing an augmented version of a medieval string instrument that I designed and built with Troels Hammer, Alex Baldwin and Edvinas Peciulis in 2015. We are amongst 24 semi finalists, and the competition is hot!
Pat Metheny is amongst the list of previous winners, and judges. So that gives you an indication of how much practice I need to put in! Unless Troels decides he wants to perform instead, in which case I will be standing by with spare tennis strings if the instrument breaks.
A Digitally Augmented Medievil Instrument
This was a wonderful project that came out of a proposal from Musikmuseet in Frederiksberg, Denmark.
We addressed their desire for increased visitor interaction by building a replica of an instrument in their collection that the public could play. The instrument we chose was slightly taller than the average double bass, had only one string, and sounded like a trumpet: The Tromba Marina.
We made the instrument more playable by feeding sound from the bridge, electronically, back into the body. We also simulated the sound made by the instrument’s vibrating bridge using pure data.

For this project I designed an audio based computer game. The player controls the environment with their voice. The Pure Data patch that I wrote is able to distinguish between various vocal sounds.
- Open vowels
- Hard constanants
These four sounds were used to drive an external physical model of a D.C. motor.
Saying ‘ssss’ or ‘zzzz’ is effectively putting your foot on the gas, say ‘ka’ or ‘pa’ changes up a gear. ‘Aaaah’ turns on reverb and a ping ping delay to simulate other traffic, and, for the icing on the cake, ‘sssss’ switches on a randomly sweeping notch filter, the center frequency of which jumps further, with increased time intervals, the louder the input voice. This has the effect of making the motor sound like a speeding boat. ‘Zzzzz’ switches off the notch filter, and engages a three tap dynamic chorus effect, again controlled by amplitude. This makes the motor sound like a plane.
Despite making people look quite silly, it proves to be quite an addictive waste of time.
Despite some glitches in the behavioural routines, this is the interactive product I am most proud of
Having worked on this project as part of a small, but superb team, for a little over four years I feel deeply invested in it’s future.

How movement affects audience perception
In this experiment I set out to determine if musicians can sell themselves more convincingly, just by moving a bit more. It turns out it’s true. it may be obvious on an intuitive level, but obtaining proof is another matter!

ACPAD – This new interface for musical expression looks like a great deal of fun. In fact it is very similar to an idea I had recently had, and was considering mounting to my short scale bass guitar. I eventually decided to put that bass up for sale and watch an episode of Star Trek Voyager instead. This was no great loss to the music world. This device is clearly far more advanced than anything I was dreaming of. But, I wish they had gone in a fundamentally different direction.
There is a tendency, when music instruments and tools arise from technology, for the inventive mind to find ways to replace musicians, rather than empowering them. Here we see a guitarist performing the roll of guitarist, drummer, keyboard player and programmer. It’s very impressive, and will no doubt facilitate the production of fresh music. But would it not be more exciting if the interface was just controlling the sound of the guitar. Allowing varying amounts of delay, distortion, portamento and so on. Yes, these effects can be produced with the use of pedals, but I suspect with less freedom and control.
A great example would be Future man, seen here playing his crazy home made percussion instrument that he started work on in 1988. It’s not a world away from Acpad, but I feel there is a stark contrast in the philosophical approach. Roy Wooten, is a musician first, then an inventor, and he explains something of that process here.
For me, the most exciting thing about music is the interplay between musicians. Let’s not use technology to kill the band!
Synthesizer interfaces using laser projection are nothing new. Jean Michelle Jarre was famous for playing around with such devices back in the eighties when I was a kid. Lenovo are not the first tech company to play around with interactive projected control surfaces either. This review (below) would suggest that they have not cracked it. But I still want one.
Being able to project video or a presentation on a wall from your phone sounds like fun. Being able to flip that around and project a computer keyboard onto the table sounds like even more fun. Being able to project a piano keyboard onto a table top and play some music with tolerably low latency sounds like as much fun as you could have from a mobile device. So I’m going to be watching this market very closely. My next smartphone might not be the S6 edge after all!
