I think this one would be a straightforward firmware update. Right now CV1 and CV2 outs have some great sources such as LFO, envelopes, aftertouch, velocity, etc. I was surprised that the pedal input wasn’t one of the sources. The KeyStep 37 broadcasts expression pedal input as MIDI messages, so that’s good, but I mainly use the KeyStep 37 as a controller for my modular setup (and also as a controller for my MiniBrute 2s).
It would be nice to be able to route the pedal output not only as MIDI messages, but also as CV output. I guess you’d need to add a new mod source for CV1 and CV2, and be able to set the voltage range that the 0-127 MIDI range should map to (perhaps with a “curve” option like we have with other mod sources, etc.)
The same probably applies to a simple on/off pedal input as well, since the pedal can be either an expression or sustain pedal.
Hope the team will consider this. Thanks!
