Cool little plug.

I saw this on KVR today. It outputs through your internal piezoelectric speaker instead of the host. try playing a whole bunch of notes really quickly!!

^^^^^this is similar but older, probably mentioned before^^^^^

Cheers for this man, I dig it! It sounds really decent even if the notes are pretty random

that is so motherfooging awesome!

shame you cant record it

The 0303 one is funny because the tempo is really unstable. It has a randomize button though.
