Let me make another proposal:
- There are GMPI defined gesture start and gesture end events. These are
just like other events, in that they have timestamps and so on. The
value of the gesture event is a 32 bit int ID. Think of these events
like note on and off, as GMPI is planning those, just for "controls"
instead of "notes".
- There is a host-supplied function GetUniqueGestureID, which a plugin
can call if it wants to start a new gesture and it wants a
globally-unique ID. Nested hosts simply pass this request upwards.
- Only one gesture can be active on a particular parameter at one time.
There is no need for every parameter to have the gesture ID. Unlike
notes, there is no need for "gesture polyphony." It is a requirement
that the host send a gesture end event prior to sending a second gesture
start event.
