If you thought that the 312-key Chromatone synthesizer had a few more keys than your everyday piano, just wait ’til you get a load of the Tonal Plexus and its even more plentiful keyboard design.

The Tonal Plexus series of keyboards is a micro-tonal input device featuring rows and rows of buttons which generate tones with far more precision than an 88-key piano can handle.

Created by H-Pi Intstruments, the Tonal Plexus comes in variants from a compact 2-octave, 422 key controller, all the way up to a gigantic 8-octave keyboard with a whopping 1688 keys.

The keyboard layout is based on a traditional piano keyboard pattern of 7 white and 5 black keys, but each key gets a bunch of additional variants, including 7 naturals, 7 sharps, 7 flats, 7 double-sharps, 7 double flats, 6 triple-sharps and 6 triple-flats.

In case you’re keeping count, that’s 211 unique keys per octave. For some reason, I don’t think that you’ll ever run out of notes on this keyboard.

Prices range from about $1300 to $3800, depending on the number of keys and whether or not you choose to include the optional synthesizer/amplifier module, or you just need a MIDI controller. You can check out the complete catalog here.
