This might be the most interesting usage. A compression ratio calculated
by the note on and note off velocity to transmit a changed note of
velocity might be less useful for a master keyboard, but a master
keyboard should support custom velocity curves not only for note on
velocity, but also for note off velocity, anything else seems not to be
the task of a master keyboard, but a task for the controlled synth.
