Feedback Piano
I originally built this instrument to make the sound design for a production of Rosencrantz and Guildenstern Are Dead. It is a computer-controlled feedback loop which engages the strings as a sort of resonant memory.
Any sound made in its vicinity will hang sustained in the air as it is slowly transformed. Its sound is at once familiar and alien, a fitting backdrop for the surreal world inhabited by these characters.
You can hear it on the album Diverse Recourse by Joe Beats.
LoopShaper
This is an app I designed for the Percussa Audiocubes. It allows you to control any VST instrument using two of the cubes.

ResoDrums
Played like a hand drum, this is both sensor and speaker. The sounds you are hearing are coming from the ResoDrum itself via a transducer bolted to the underside. Tap on it lightly and you get small percussion sounds; hit it hard and it goes berserk.

The Flote
The Flote is an easy-to-use, affordable, DIY musical instrument that allows people with limited mobility to use their head movement and breath to produce music with ease, thus amplifying small gestures for a big impact.

One day, I started talking about slinkys with my favorite DSP supergenius Jonathan Abel and this was the result.

The Pond
The Pond is a human-scaled, proximity-based non-linear sequencer. A ceiling-mounted projector fills the floor with light. As each player enters the pool of light, a circle surrounds them and follows them as they move. Each player carries a ROCK, an accelerometer-based wireless controller. A quick shake of the ROCK triggers the player’s identifying sound and, like throwing a rock into an actual pond, causes their circle to expand. As the circle spreads to touch another player’s circle, it triggers a convolution of both their sounds resulting in a complex melodic sequence.
