> > Do you mean hardware control surfaces? > Yes OK, so in this case I think GMPI could support it, but there aspects to control surface integration that are very host specific. Other topics (and ultimately the specification) will hopefully cover issues about how parameters are represented, named, organized and discovered. This would be pretty elemental in a control surface integration system. Other issues of importance with control surfaces are consideration for multiple "gesture sources" attempting to write to the same parameter at the same time. But in any case, I don't think there is anything in the current description of what kinds of plugins GMPI supports, to preclude using GMPI to interface to a control surface. ---------------------------------------------------------------------- Generalized Music Plugin Interface (GMPI) public discussion list Participation in this list is contingent upon your abiding by the following rules: Please stay on topic.
