TBX1 demo 1

"This is a demonstration of the H-Pi Instruments Tuning Box TBX1 ($299), a device which retunes standard MIDI keyboards so that any key can play any pitch you want. In this demo, a Yamaha PSR-310 ($149) plays an arpeggio throughout, sending MIDI notes of a C-Major chord, which you hear at the beginning going through the box in bypass mode (no retuning). That chord then gets retuned in 15 different ways, and I noodle around (not much keyboard skill shown here) over the arpeggio in each tuning. Each of the 15 presets stores a tuning and a bank / patch change. The box stores up to 128 tunings in 4 layers = 512 tunings, each 128 notes. Check it out here: http://www.h-pi.com/TBX1intro.html"
