One of my early bits of recorded looping is all drifty on the actual loop part (Roland GR-500 into Digitech RDS3600) but was built on top of a drum pattern built out of several cycles of different lengths carefully programmed into a Korg DDM-110 and DDM-220. The bass line was also somewhat inspired by Terry Riley's In C in that that I wrote down a series of figures and handed them to the bass player I was working with and said play these in sequence at whatever rate of progression feels right to you. I don't think he particularly appreciated trying to work with the drum pattern, however. http://grubmah.com/music/midnight_train.mp3 Mark
