Key change button sending MIDI Prog Change too?

OMG the E-mu rack units are awesome for multi-timbreal pads.  Darryl turned me on to the Orbit v2.  I think that’s the best E-mu rack unit so far (insert Morpheus comment here). I have a couple of the next generation units too, Audity and Extreme Lead. I like them because they have some knobs on the front panel that directly manipulate the patches.  Unfortunately the ones I have are not the “ultra“ versions, which means they only have one stereo pair output.

Just a reminder you have to use the Poly chaining to get multiple simultaneous patches for the Pad.   Well I guess you could double up the voices on the same midi channel too. :-)
