This is a different issue. It may in fact be partly affected by gestures,
though.

What you are really saying (I think) is that you need to set the velocity
and pitch values for a note, then initiate that voice.  That's fine for
velocity and pitch, MIDI already handles those.  But we need to allow more
than those two magic controls.

So the general problem is the need to set a number of controls atomically
before a note activation.  David has a good description of latched controls
(from XAP), and I agree largely with his position in that sub-thread :)

Those sets may all be part of a single gesture, but that alone doesn't solve
the problem UNLESS we overload the use of gestures from what I currently
understand.
