Yes, using PLAY Orchestra from East West.
What did you mean by "main main for the sound"? In the PLAY Instrument interface, there is a pan dial - which if I manually turn it - it changes the "mic placement" basically - which results in panning. But no envelope I put in either the midi or synth track controls that pan control, and the envelope that is available in the list of instrument specific envelopes called "instrument pan" isnt controlling anything within PLAY, so I'm not sure what it does.
I can insert a track pan envelope on the synth output track - and that is a workaround and accomplishes what I want - but it doesnt seem like the "correct way" to do it - and that doesnt solve the problem that the other 30 or so instrument specific envelope options in the track don't control anything within the PLAY instrument interface - let alone anything at all.
I'm stumped.
