recently, I've made some Cubase Drum Maps for GPO's percussion and keyswitched instruments. Percussion is straightforward, I simply assign the appropriate Drum Map to a midi track.
For keyswitches, I usually use a second track (one with a Drum Map) for each keyswitched instrument, using the same port and midi channel as for the track with "real notes" in it. Makes it quite comfortable to find and change articulations.
Anyone interested? If so, is there a place where I can upload such files? There are 35 files, one for each GPO instrument that could use such a thing, the maps are created with Cubase SX 3.1 (I hope they work in other versions as well).
