"Under the hood, these are actually Korg N5EX synthesizers with a custom keyboard built specially for Tokyo Yusyo (probably also by Korg), with each key being velocity and channel (mono) aftertouch sensitive. Please note that the Chromatone keyboard is not at all like a matrix array or other "microtonal" type keyboard. These are actually 88 key keyboards shoehorned into the form factor for a 61 key keyboard, with each key having multiple key tops for ergonomic play. I used these as MIDI controllers, but you can just as easily tap them for the onboard GS/XG/GM soundset.
I encourage you to visit the maker's websites [
here and
here] and tour YouTube to understand more about the Chromatone keyboard and the MUTO method for notation and playing these keyboards if you are not already familiar with it. The onboard synthesizer engine, features (e.g., sequencer), and operation are that of the Korg N5EX, so please see the manual for that keyboard (on Korg USA's website here: [link removed by eBay]) since Tokyo Yusyo supplied no additional documentation with these keyboards.
I reiterate: these are not matrix array 'microtonal' keyboards."
