Hi Mike,
We do not offer telephone support, but you can always call my colleagues at our US distributor, www.ilio.com, they do offer this service, and they´re MUCH better on the phone for sure! Here is their contact information.
I think you are seeing VE PRO a bit too complicated. There´s not much routing necessary:
1) You load your plug-ins.
2) You assign the MIDI PORT and MIDI Channel (on top of each channel in the mixer)
3) You assign MIDI tracks in Sonar that send MIDI information to the chosen MIDI PORT and MIDI Channel => assign Vienna Ensemble PRO on these tracks.
4) You can mix all these signals in VE PRO. Additionally, you CAN (but you don´t have to!) route multiple audio channels back to Sonar.
5) MIR PRO: You can use MIR PRO in the background of VE PRO, which means that your instruments will perform in a virtual hall. But that´s maybe the next step, after you have mastered VE PRO.
Hope that helps!
Best,
Paul
