The Chromatone is a Jankó layout keyboard I got this for the price of postage as part of a give-away the inventor was doing. I wanted the prettier, larger, (and with a MIDI-through port,) Wholetone Revolution, but those were gone by the time I applied. Since, there's been another model made called the Chromatone-Mini, which is a small, barebones, MIDI controller with LED lights and shit.

I thought it would be a fun MIDI controller, but I never use it, and don't like the mushy key feel.
