I actually have 1 instance of SSAATTBB using 8 Opus VSTs and 8 VEP ports. Works wonderfully. I might have misinterpreted what you mean by “instance” (VEP instance or Opus instance).
… and yes, port 1-8, channel 1 routing in Dorico.
OT: I’ve also rediscovered Voices of Opera and although they don’t have word builder functionality, they are quite nice as soloists on “ah”.
yes you can do it that way, though if my memory serves me correctly, it used to be problematical in Dorico so I got in the habit of using a separate instance for each part and route all to port 1.
Yes I meant one Choir instance in VE Pro with 6 Opus plugins loaded the first 4 for SATB (Diamond) and the other 2 for Women and Men Choir (Gold). All VE Pro outs routed to MIR. In VE Pro routing to port 1, channel 1, out 1-2, port 2, channel 1, out 3-4 etc.
All Opus plugins with Wordbuilder loaded with the full text for the piece. Played through with Learn to stay synchronized with Dorico. In Opus all internal routing at default. So Opus 1&2 with channels 1-14 channels for the combined multi with WB. This works but at least for me with regular hicups. At least once in a daily session VE Pro will crash which it never does when I do not have the choir instance active in VE Pro. Maybe CPU related.
