Well, they *are* special in that they're latched only at certain points. The problem is that if synths cannot effectively *implement* it that way, it becomes the host's/sender's responsibility to know the difference, and make sure that these controls are handled the right way. And unless the host/sender can tell the synth exactly when to latch the values, there is no way to get this right. What I'm saying is that synths should preferably behave is if *all* voice controls ever received are tracked on a per-VVID basis, so they can be latched as intended when the synth decides to start a physical voice. That way, you can play continous control data on latched control synths and vice versa, without nasty side effects or "smart" event processing in the host/sender. Obviously, this just isn't possible if the number of VVIDs used to control a synth is unknown or very large. However, I don't see a reason why you would use many more VVIDs than there are physical voices, so I don't see this as a real problem. Synths that don't allocate physical voices as soon as a VVID gets it's first control may have to allocate virtual voices upon connection, but I think that's acceptable, considering the alternatives. //David Olofson - Programmer, Composer, Open Source Advocate .- The Return of Audiality! --------------------------------. | Free/Open Source Audio Engine for use in Games or Studio. | | RT and off-line synth.
