I know, if one can work with a maximum of 64 steps, then all is fine. But I want longer buffers like two and a half minutes. So…
(1) decide for a tempo,
(2) decide for the loop lengths you want,
(3) calculate the number of steps that equal the loop lengths you want,
(4) do empty recordings inside the OT at the tempo you want and abort these recordings after the calculated number of steps,
(5) store and name these recordings accordingly to CF card
(6) load the recordings you want into the recording buffers of the pickup machines
Step 6 is the tricky one: Normally you can double tap a track button to see the according sample slot list, and the 8 recording buffers on top of the sample slot list (in case it is a Flex machine track). But double tapping the track button of a pickup machine track only gives you the menu to chose a different machine for this track.
So you have to double tap a track with a Flex machine on it to get to the sample slot list with the recording buffers. Now use the cursor up/down to select the recording buffer with the number of the pickup machine track you want. Then press “yes” twice, which will open the audio file selector, select the empty audio file you named & saved in step (5) and enjoy.
UPDATE
I just noticed that I forgot to mention the final steps, which are crucial:
(7) Press Play on the OT Sequencer.
(8) Press Play on each of the Pickup machines in which you loaded the empty recording.
Without these final two steps it does not work!
Sorry that I forgot this.
