They often can. Like I said, the Juno DS has 4 assignable knobs, you can make them send any CC you want. But pitch bend is a special case (it is neither MIDI CC nor sysex, it is its own thing), and I don't know that I've ever seen a board that lets you use the pitch bender for anything other than pitch bending.Just thought there would be a way to send custom midi messages with midi keyboards. Just seemed logical since they already send and receive note and pedal and pitch bend commands.
Why can they send CC messages as well?
Yes, pitch bend is a standard, that generally works across all boards (except boards that don't support pitch bending at all).I had a roland Juno hooked up to an E-MU and the E-MU received pitch bend messages from it without any programming.
Pitch bend is not a CC, but if the E-MU let you route pitch bend commands to do something else, cool. That's not common, IME.I could also do internal patch cords on the E-MU so that it could route pitch bend CCs to LFOs and other stuff.
