It would be nice with a polyphonic arpegiator, that could randomize parts of it self! Also randomize notes, within selected scales! And it would be cool to have a seperate tempo for the arps, and if you control that tempo with say the pitch weel, it would snap back to beat when you let go! The tempo scale should be from 0 to 1000bpm! ...Glitch-fx? :P
