Don't think that is quite correct - you can play wav channel patches with a MIDI keyboard via Arduinoboy (I assume with a PS2 keyboard too, as it's basically the same thing?)
I've got a tune built on a modification of this patch: https://youtu.be/l8QDTW2pciA
that was all played over MIDI.
You use program change messages to select patches by instrument number, and wav channel patches definitely play OK - I don't think it matters which channel you set up the blank chain in either IIRC (although the entire thing is a little bit temperamental to get working - or seems to be for me.)
not sure about Kits though tbh, never tried as it always seemed easier just to sample the hits than play them over MIDI.
