A few suggestions
A few suggestions that might or might not Help:
-A Mixer Pop up that can pin itself to either the left, right, above, or bottom side of the editing area.
-A Gong sound for the Cymbols section in the Input Note toolbar (Drumset>Input Note>Select Drum Sound)
-Synthesizer balancing for individual Instruments (To Give Base Drums a more Promonent BOOM when struck and to keep headache inducing instruments held notes in check if at a dynamic higher than mp (Although volume could help with that as well))
Those are all the suggestions I have for now, If you have any comments, please add to the discussion :)
