PS regarding robot pianos:
A workaround for one issue would be to select different velocity curves
by a CC message, to fit to different parts of a song played by a piano
master class. Software even could transmit measuring probe data from
the robot piano to the software via MIDI 1 to determine an appropriate
velocity curve. Even within the limits of MIDI 1 the problem with
robots is that robots need a completely different approach. A better
MIDI standard would improve the situation for robots, too, but never
ever does solve the robot problem.
