You can find the M-VAVE FM-1 on Amazon.

"My attempt to FM-1 collective madness. Yesterday got mine and was a bit upset by how shitty it sounds. So I thought what if we take LOOPA DSP, offload all the audio processing to a phone, use FM-1 as a control surface and send audio back over USB? Here it is, a fully-featured sampler + looper PoC which doesn't sound like a toy

0:00 Sounds
0:18 Sampling
0:28 Granular sampler
0:40 Making a loop
0:48 Adding drums and bass
1:07 Doubling loop
1:14 Melody
1:30 Tape speed"

"A sampler + audio looper (8 tracks) for Android with the M-VAVE FM-1 as its hardware front end. The phone does all the sound; the FM-1 is the control surface (keys, buttons, 7 encoders), the second screen (240x240, drawn with SysEx commands) and the audio output (USB audio). All DSP is original code in engine/dsp (no third-party audio engine); the only library is KissFFT (BSD) for the Paulstretch mode."
