Doesn't AD include lots of actions that GM doesn't, like cymbal mutes and such?
Doesn't that affect the mapping and/or conversion?
I guess any AD extra actions just need to be remapped to the bit bucket, or to an alternate key. Better no note, than the wrong sound, eh?
I looked at the conversion rule sets that ship with MIDI file Mapper, and saw one included for "EZDrummer to GM", but none yet for "AD to GM". But there is one for "GM to AD".
You would probably need to lay out the drum map specs for AD & GM side by side, then create the custom XML rules for what you wanted to replace. That option is provided
