Microtonal Keyboard Converter

Got a standard MIDI keyboard? Retune it! TBX1 makes retuning as easy as pushing a button. Attach this little box to your synth and instantly change the tuning to anything you like. It comes preloaded with 128 tunings for you to try out, and it stores tuning tables in 4 layers, totalling over 500 tunings, which you can easily edit using the included Tuning Box Editor cross-platform software. Set up your own tuning, upload it to the Tuning Box and plug it into any General MIDI controller and synthesizer to make your music. Portable and ready for the stage, it even runs for eight hours on batteries.

128 tables x 4 layers = 512 full range programmable tunings with Tuning Box Editor software
