Hi Mike,
Thanks for the feedback. I'm not really bringing the tune into RealBand to adjust volumes, I am doing it to fix/improve a couple bars of one of the Real Tracks. Ideally, I would like the volumes, and all tracks to be in place when I save the file in RealBand and then re-open it in BIAB. Even if I could make the corrections and have the tracks remain, I could then reset the volumes back in BIAB. But the track doesn't preserve, so i'm not left with a lot of options.
