MIDI-controlled circuit bending interface

Daniel Park describes his approach to controlling circuit bent Alesis QSR Quadrasynth through MIDI data, simplifying control for musicians –

With this design I wanted the entire bent interface under MIDI control. Any MIDI source: MIDI cc’s, program changes, tempo synch, MIDI machine commands, notation can be routed to any destination on the circuit bent interface via sysex programming.

The circuit bent interface features two patch bays on a bank of rotary switches. One patch bay is 10 points dedicated to the effects processor bends while the other patch bay  is 24 points dedicated to the oscillator bends.  With rotaries you can get creative and efficient. No more massive amounts of drilling for point to point patch bays.
