Not tryed that yet. But thinking that it would be nice with att simplyer way to do that, like a window for Realdrums in the Opt. > Preferences > Set Drum Volumes > "realdrums", like a mixer., with possibilty for reset standard in case of the mixing goes wrong.

Maybe it´s to much to ask for as a wish for a mixer for realdrums. I do not know much about the programming, but i think it´s a big and complex work for programers. However i will try to follow yor tip later on, and se what i can do.
