I spend a lot of time trying to build new musical instruments and interfaces (thanks a lot, Perry). Here are two of those that I've been working on lately.

The squeezeVox is an instrument Perry Cook and I built to control various singing voice synthesis models. Working independently, we came up with several different incarnations of the instrument, each with a different suite of features.   The elBo is an instrument for live spatialization and diffusion of sound in space. The instrument translates gestural actions into spatial location, point source velocity, pan width (spread), effects parameters, and other diffusion data. The guts fit in a single rack unit chassis.
