I just finished a patch editor with preset morphing for the Nord Drum 3P
nd3peditor.zip

It’s possible to save sounds into the patch and also to export the preset banks for each pad as files.
It listens to MIDI on channel 10 (you can change parameters on the device and save them into the patch) and sends MIDI on channels 11-16.
It probably would be possible to add sysex dumps from the device into pure data but i couldn’t get my head around backwards engineering the sysex format.
Morphing all the sounds at once sends A LOT of Midi so it slowed down the sequencer i had running in pure data, but playing morphing sound by hand should be really cool too!
