This has happened to me several times, but I have never figured out why this is happening, so I haven't been able to correct it.
In GPO4 (Aria) in the Mixer view, I establish the instruments and usually go with the default slider settings. Particularly in an older piece where I have to reprogram the instruments to Aria, when I press Play, the sliders move to different positions. I re-adjust the sliders (and even Save), but they revert back to these undesired positions as soon as I press Play.
I have Deleted Aria, brought up a new instance of Aria and reprogrammed the instruments. But this has no effect on the sliders changing when I press Play. No other cc's appear in any track except 1 and 7 (which is usually about 90). The sliders typically go to around the 30-40% position.
What is happening and how can I remedy this situation?
