The third in Yamaha's new ReFace range - these guys are all the same form factor, we have the ReFace CS (synth), ReFace DX (FM Synth) and now the ReFace YC - an organ machine. With the same mini keys - surprisingly playable due to the mass of the unit and the quality of the keys. This one does organs.
There's also a reverb, drive and leslie effect too, as well as drwabars for real-time control of the five organ models.
All the ReFace units, have built in speakers and battery power, which means you can play anywhere - should you wish. They also have MIDI io and USB MIDI (no audio).
