Speaking of controllable patchbays...are any you guys familiar with this chip from AD: http://www.analog.com/en/prod/0,2877,AD75019,00.html
There was thread on the ucapps/midibox forum a while back with this idea in mind - looks pretty straightforward to setup with MIOS (just coding would be the tricky bit unless u know the coo with that)...
Anyway, just after some feedbak on using these chips and consequent effect on audio signal...
Cheers
