Yes, Yoshimi accepts most standard MIDI CCs

This is a real problem. Yoshimi state is a very complete setup and is intended
to restore it to *exactly* the condition it was saved at. If you are changing
anything at all after the state has been loaded you break Yoshimi's model.

I've had this discussion with other sequencer builders. While I can appreciate
the desire to put things in a known condition, it's my belief that any such
changes should only be made *before* a state or patch set load.
