I'd really appreciate some help with this! I've tried everything I can think of and can't resolve it. I've posted in the REAPER forums as well.
I'm running the latest pre-release of REAPER, but I see the same behavior in 3.4.
This is with the ARIA Player, 5 instruments, routed Out 1/2, 3/4, 5/6, etc. Each is assigned its own MIDI channel. I don't think there's anything wrong there, since the same setup is working fine in SONAR.
Here are my ARIA Player I/O settings:
Here's a video of what happens when I play through each MIDI track with Record Monitoring on. Notice how the Audio is routed as I change instruments.
I tried the same thing with REAPER's automatic track building (Audio and MIDI) and I've gone through the multi-out synth tutorials again, and still I'm not getting the routing I expect (eg. VLNS1 shouldn't sound with VLAS & BASSES).
Could some kind soul tell me what I'm doing wrong and put me out of my misery, please?
Thanks much in advance-
