Soundplane A

The Soundplane A is a computer music controller with the sensitivity and feel of an acoustic instrument. It detects a wide range of touches on its walnut playing surface, from a light tickle to a very firm press. The Soundplane A can be configured as either a 150-note keyboard with position and pressure sensing on each key, or as one continuous surface.

The playing surface is a material custom
developed for us, an articulated sheet of walnut veneer bonded to a fiber backing for strength.
The case is milled out of alder, a sustainably harvested
Northwest hardwood. We have sourced all of the construction locally and
test and assemble Soundplanes by hand here in Seattle.
The entire instrument is about 28 inches wide by 8 inches deep by 1 inch thick.

Included with the Soundplane is Aalto for Soundplane, a custom, signal-driven version of our patchable software synthesizer. The Soundplane client software can send MIDI and OSC messages to control other software and hardware.

The Soundplane’s continuous capacitive sensing technology is patent pending.
It is also described in Randy Jones’ NIME paper from 2009 [pdf] so that you can make your own.
We encourage and support related DIY experiments via our forum.
