This is an Adafruit Untztrument wired up to an as-yet-unreleased Teensy-LC, with my custom midi sequencer code. It's about 80% complete, it features 3 instruments, 8 patterns per instrument, a pattern mapping mode and 8 rotary pots which can also be mapped to any cc control in your midi software. There is not enough memory to sequence the Pots but you can still have fun twiddling them to bring in effects or wobble your LFOs/cutoffs. It should be complete in a couple of weeks, around the time of the release of the Teensy-LC and the code will be released as open source.
