Pickup Machines record into their respective track recorder, so T1-4 in this case.
Remember that Flex Machines (T5-8) can play any track recorder. In this example, the Flex Machines on Tracks 5-8 are set up to play Track Recorders 1-4.
So, the Pickup Machines are sampling as normal, but we also have a set of 4 different tracks playing the same source, but with different settings (Rate, Effects and so on).
Hope that’s clearer, let me know if not
Thanks for the listen!
