General Midi Drum Map Drums are not played with notes but with events. You trigger the drum or you don't trigger it. But there's no such range thing like a piano has or strings or synths. Back in the 1980s some people thought, it would be good to have something like a drum map. Switching from a piano to strings only needs some adjustment in octaves but notes sound the same. Switching from one drum set to another could cause a mess or silence. Without a standardized assignment of note (events) and drums it's quite hard to move from a jazzy drum set with brushes to a more straightforward rock drum set.
