Because the > control changes does not occur here, the host can create events on any So the host has to call this method for every frame for which there exists an event? And the host then needs to interpret and propogate the returned list of events and propogate that back to all controllers. ick. If we want to explore that route, how about a 1-call per event target per timeslice method. Pass all the events to a plugin->control_events() method. This method can validate events (or not - this may not be a good idea to allow control changes to fail), recognize linked controls and generate events for them, and enchain the passed events. The method can return a list of events that need to be passed back to controllers - errors or linked-knob changes. The simplest plugins can do nothing at all for this hook. This also allow for spontaneous changes of controls. It really splits the processing of events into pre-processing and processing. Which may have bad effects and good effects on performance. Take some stuff out of the DSP path, but duplicate some effort. It should be safe, too, as I think we can assume that once we reach the boundary before the next time slice, we know everything that is to happen in that timeslice. This is still not very pretty. A plugin may have many event targets - one for each knob, even. It adds a lot of function calls per-timeslice, which is exactly where you DON'T want overhead. ---------------------------------------------------------------------- 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.
