Instruments for exhibition – Control Surface

Two unusual electronic instruments that were part of a greater ensemble, built for an exhibition in China. Idea and hardware by Daniel Araya. Programming and I/O-electronics by 9bit.

The Control Surface is a Standard MIDI Interface compliant unit, built to interface with a MAX MSP patch on a host computer. The Control Surface has about 40 faders, knobs, switches, touch controls and a status LED that is controlled from within MAX MSP.
