This is some sequencer code for an Adafruit Untz (4 x trellis Board) with an Arduino Uno and hardware midi out. It plays eight notes as a stepsequencer and gives them out on an Arduino Uno over MIDI Serial. This is differnt to the actual setup, where a Arduino Leonardo was used to pass the midi via USB - which is bad if you just want to trigger some Hardware-MIDI audio gear. its based on the Sequencer Code by Adafruit
