Just use a Flex Machine directly for that. You don’t need a Pickup Machine to do what you describe above.
Sample straight into a Flex Machine track, then do whatever you want within that track.
Then go to your next Flex Machine track to record your next part. Rinse and repeat.
One caveat: The slicing process is unfortunately not a one-click process. These are the following steps:
- Open Audio Editor on the audio you want to slice, within the track playing the audio.
- Do a Create Slice Grid.
- Select number of slices
- Select linear locks or random locks (this assigns locks to slices so you can trigger them from the sequencer - linear means slices are assigned in order, while random is random).
On my semi-ambient, quasi-loop based tracks, I get around this by building up loops in a pickup machine track, then quietly doing the slicing steps on a flex machine track while the loops play on the pickup machine track - so the listener doesn’t hear an obvious interruption in my playing.
There are other audio slicing shortcuts like creating the slice grid and/or assigning the locks beforehand.
