Just to add to the discussion in a different direction....OT rules for creating granular-ish drones....but pair it with an Eventide (Space, Eclipse, etc), and you are in another universe. This includes resampling the reverb back into the OT for further mangling. OT is a dream for drone experiments....but Eventide reverbs are classic fundamentals for drones. Put the two together, and you have drone bliss!
