Hi Jay,
in your example, we would be using 7, since each instrument, while having multiple articulations, is a single instance. Simple.
The thing is, working in the traditional way sucks.
We have a midi multi triggering an instance of VEPro that goes to a slave run on a remote computer that triggers a second VI that has multiple outputs that are sent back to Logic on multiple audio channels... it a huge mess, and it's impossible to gain stage and mix in any kind of a logical way. You can only use region based automation.
If a way could be devised where we have 1 channel in Logic that does midi and automation (1 on 1) rather than 16 (your midi multi) plus 1 (and all the cabling in Logic we have to do to make this work) and then the returns in Logic, PLUS the setup in VEPro server (huge mixers and I/O setups.
So PLEASE tell me a simpler way, if you can figure it out.
George
