As long as we are moving slides...why not eliminate the valves entirely
and just motorize one main slide (like a trombone). You would eliminate
2 costly motorized slide assemblies and reduce the power requirements
needed by them. As a bonus, the technology could be applied to the
trombone as well.

I'm not talking about sensing and trying to correct every note, just
detecting which "valve" combination is being used, which overtone is
being produced and adjusting the length the same each time (perhaps
still with some adjustment, using the now idle left hand thumb against
some sensor, or even a foot pedal). The "third component" would be
UNTOUCHED by the instruments I was thinking about. Enharmonic systems
(like my antique Besson cornet and professional tubas and euphonia)
provide two settings for the first and second valve lengths based on the
position of the third valve.  What I'm talking about would not eliminate
the "third component" any more than an Enharmonic instrument does. A
21st century enharmonic system.

Be a little adventurous. ;) It would be fun to have a trumpet that would
automatically have the one previously chosen corrected length for every
note.  The same basic electronics could detect valve combinations and
adjust existing valve slides on an existing soprano brass instrument,
and easier to prototype on an instrument that already has triggers on
1&3.

Someone who can't play in tune with a normal instrument would still be
incapable of playing in tune with this Robotrumpet (tm) :) . You'd still
have to listen to everyone and accept the group pitch, and occasionally
lip high or low depending on the note in the chord you are playing. It
would be a interesting design exercise, I'd try to do it myself if I
thought there was a chance of a commercial success.
