I sampled a few sounds from my Reface CS Synthesizer and made them into instrument racks. I recorded the synth direct as well as with a stereo pair of microphones on its small speakers. You can mix between the two sources. In addition I sampled the physical key clicks while pressing and depressing the keyboard which you can mix in independently.
Included are 5 Instrument and 32 Percussive Racks.
More info about them as well as short demos of each sound can be found in this video:
