I did a demo very short few bars using my above mentioned techniques. Just 4 Impulse kits / 1 delay / 1 single beat repeat and all MIDI no eq.
Absolutely no precanned loops where used either.
Beat repeat was only used on one track with clip automation.
Ditto for the delay.
All other automation was of Impulse velocity and impulse kit volumes / pans via Live's clip envelope propertie etc ......
Wish I could attach the damn thing
