It’s possible to write drum notation with a drum pad like the akai mpd218
Dorico can certainly communicate with the device. Someone more into the specifics of percussion work will have to comment on whether or not you’d be able to map specific pads to specific parts of a “kit”.
exactly what i mean
Yes, you can normally map each individual pad on a device like that to a particular MIDI pitch. So you would set Dorico to use either staff position or percussion map input, and then map the pads on the device to the necessary MIDI pitches.
