OK, after experimenting more, I want to report back with my experiences. They are not good! :-)
Here's my scenario: I have DP 7.24 open, along with VEPRO 64 bit. I've loaded one instance on PLAY into VEPRO, with one instrument loaded (Hollywood Strings part). This is a very simple situation, trying to resolve basic issues.
I set up one MIDI track, pointing to VEPRO channel 1. I've got the PLAY channel in VEPRO set to 1, matching the DP MIDI track channel.
I've set up the VEPRO AU within DP, outputting to one of my hardware stereo pairs.
I can play the string patch from my MIDI keyboard no problem, either with VEPRO or DP in front, doesn't matter. When I'm in DP, no matter which MIDI track I've armed, the VEPRO patch sounds!!!! So, say I arm the Trilian bass track--I get bass AND strings! It's as if VEPRO is receiving MIDI no matter which device or channel I'm record-enabling in DP.
It seems that I have a MIDI setting wrong in VEPRO, I'm just not sure where to start. Is there a way to "slave" VEPRO to only respond to the MIDI device/channel I specify from within DP?
The other odd thing, and this may be the telling thing: Although I can play VEPRO from DP, recorded MIDI track data WILL NOT trigger the corresponding PLAY sound in VEPRO! This leads me to believe 2 things:
A) DP is not correctly sending MIDI to VEPRO, and
B) VEPRO is taking over my system's MIDI ports, entirely.
The manual really is no help, I would appreciate some step-by-step assistance to get this software working! I don't want to attempt multi-AU, multi-timbral operation in VEPRO until we resolve these basic issues.
Appreciated,
