I got a Korg MicroKorg for xmas a while back only to find that it didn't have a sequencer built in :(. So, I've decided I'm going to make an Arduino do some MIDI IN/OUT, and act as a cool sequencer accessory. I'm using a small backlit serial LCD, some multi-color LED bar graph displays, a few HC595's, a large pot, and (possibly) 2 Arduinos. I figure I'll have two Arduinos to make the setup easier to program (master-slave config). I hope to get it to the point where the Arduino(s) will get all key, knob, and other MIDI status messages from the microKorg, and save that info in each step along with the program number (for each unique program sound). It'll then be able to play it back in sequence at a variable tempo. I'll update here if you'd all like!
