K5synth

There's not much space IN the K5 to do this. Anyways, we would need to 
use MIDI for filter triggering. The best thing to do would be an 
external rack-mount or something like that. MIDIbox has everything for 
this. You could use a knob to make the filters work, or the module that 
makes an action per note, etc.

Ask in midibox.org's forum.
