I've set up a total of seven instruments in GPO 4 as an AU in Logic 8. I record each part separately and each plays through its own midi channel. All good so far. Now I want to route each instrument to a different aux channel which I will then send to individual audio channels for audio recording. I create the appropriate aux channels by clicking on the "+" at the bottom of the ARIA Player instrument channel in the Mixer windowl. When I then click on the ARIA Player rectangle I am given a series of options (Mono, Stereo, Multi-Out [16xmono], Multi-Out[1xstereo, 15 Mono], etc.) None of these options, though, send the individual instruments to the aux channels. Only the original ARIA Player instrument shows any action.
I realize that I could just solo each instrument in the Aria Player window and bounce each part, but that seems needlessly time consuming.
This appears to be a routing problem which I can't come to grips with--though I have EZDrummer working in this manner just fine. Can anyone point me in the right direction?
