"We run across these things all the time, but what do they do? I finally picked one up, so let's find out. It seems that it has 2 modes: playback and arpeggiate. Just input some notes from a MIDI keyboard and it will play them back as 1/6th notes. Alternatively, it can play them back as an arpeggio, giving the sequence more life. Here I also demonstrate how it sequences and arpeggiates based on the order in which you input the notes, so it's pretty flexible in that regard. This is all I have been able to figure out. Please don't ask about any other features. However, if you know more about it, please leave comments. There are very few ME20A videos on here, so I thought I'd put up a useful one. MIDI to the SH-2 provided by Kenton Pro Solo MKII."

"Akai ME20A Rack Mount Midi Arpeggiator. It can record a chord or pattern and then play back based on what has been entered, almost like a step sequencer. Midi In, Out, Thru. Comes with the manual. Very Good condition. Well taken care of and clean."
