I seem to recall that Andreas
Willers had someone take an EDP footswitch and put it in a slanted project box
that had two rows of switches , it made the box one row deeper but half
as wide. I believe the smallest midi controller that does midi note command is
the long discontinued digitech PCM-10, or the also discontinued DMC ground
control, but they are large compared to what I’m talking about. Most of
the other small ones only do PC and CC messages as far as I know.
