I have a vintage psr8000.

When I play a style in,say, option "A" I will sometimes turn down the volume on certain accomp instruments.
This works fine....but.....as soon as I hit "fill-in" or switch to option "B" it plays it but the volumes on all accomp instruments go back to where they were originally.

Any way or setting to play all options in the style without the volume coming back up on the ones I turned down?
