Quick setup:
Actual: "Generate" uses all Drum kits /- sounds, also the imported ones.
Better: Excude-function for imported Kits / sounds vs. MDrummer's own Kits / sounds.
Building a song:
Actual: In Midi command method it is easy to produce a song. But there is no comfortable midi-export function without first building the song in MDrummer as well.
Better: Import-function or "translate"-function for the Command-method-Midi-Song , so it can be converted to "normal" midi.
And as said before, in general some more undo-knobs would be good.
If the functions do already exist, feel free to show me
