I set the volumes I want and then save the song, but the volume does not take effect the next time I load the song. Is there a setting to control this? I have "Allow Volume Changes" in "MIDI Options" set to on. If I turn each instrument volume up a bit, then down again, it works. But I would rather not have to do this.

I can control the volume of my solo sound with a fader on the keyboard. But the sounds usually start at max volume, so I can't turn them up compared to the comp sounds, just down.

As for the Combo volume, I have no MIDI input driver selected in BB. So shouldn't be any looping of MIDI.
