Maybe not practical as a cluster configuration, but it could certainly be used as a voice-generating device for a synthesizer, or as a controlling device for MIDI I/O, or .. both even of course, configurable according to the users needs/patch idea.

Yeah, but even for those applications you suffer from limited RAM a lot; with 16bit samples at 48kHz the thing has 10ms of audio buffer (stereo: 5ms) if you don't need RAM for anything else :S

The ADC is really nice though, 1.5 MSPS is really good for such a small/low powered thing (fills the whole RAM in under half a millisecond).

10ms of buffer is almost 512 samples @ 48kHz, it's quite a lot of buffer in audio terms!

I have a fourier transform loop running on this micro which takes 64 samples and outputs 32 frequency bins. It works perfectly for generating inputs to algorithmically driven animations including a visual audio spectrum frequency analyser.

True, you will have to write some tight code, but .. at that form factor and price, challenge accepted! Besides, 10ms is a LOT in that world ..
