Also: Mike (and anyone else), what do you think about the other issue
Tim's been exploring, i.e. is there any need to limit the number of
event sources that are allowed to talk to a given control/target?
I think this is a non-issue. Somewhere in the host a merge has to
happen. Take the example where you have two MIDI controllers, a keyboard
and some sliders. If the data comes in on two ports, the host could know
the difference between them, but for how long? At some point the data
becomes parsed for internal use. I have been trying to see why you would
want to try to preserve the source ID, and I can't see it. If they are
both changing the same parameter, then what the user hears is the effect
of the merged data. If they undo, they don't expect to undo half of what
they heard being recorded, ending up with a result that they have never
heard. They expect the data from both sources to be undone in a single
action.
So along with my suggestion to not have gesture ID's, the host simply
starts a gesture for a parameter and then pumps down the merged data.
