I guess I'll have to add an NTS-1 to my Korg family!
I've written bash scripts (using sendmidi [1]) to arpeggiate chords when I was feeling particularly lazy. It's pretty easy in midi. Figure out the root note, figure out the pattern, and just turn on/off root+pattern[i] :-).
[1] sendmidi is a great little command line tool to send midi commands to devices, or to record midi commands from devices. Its input format is plain text and you can include timing information so it's pretty easy to script music in this way: https://github.com/gbevin/SendMIDI
