"Beat707 is an Arduino Shield that adds several neat features to your musical arsenal. You get a 32 step machine, (plus 32 double-steps for a total of 64 steps) with 16 step buttons and leds, LCD screen and navigation keys. It's like the classic Roland TR707 but with some twists, as it actually has 64 x 1/32 or 32 x 1/64 steps. Plus, the 2 note-step sequence feature allows you to do bass and/or synth grooves -- it's a MIDI groove-box all in one ! The unit doesn't produce any sound, it's all MIDI based, so you can use any MIDI compatible device."
