Thanks @Open_Mike, that’s what I found too. What’s interests me is the quantized record lenght, and, especially, the auto-play. Because it’s all about live performance and serendipity, I want to have the freedom to produce a perfect loop of un undefined number of bars. With a flex you need to place a trig to get the recording buffer to play.
I have succesfully recorded >4 bar in a PU, loop off , with a Flex on another track that has the PU’s recording buffer as a source and a conditional trig so that the condition is true every (lenght of recording) and that works, but takes up 2 tracks and you need to decide how many bars you’ll record when you’re setting it up.
On the other hand, now that I think about it, The following should work too. Indeed the Flex recorder responds to the same midi commands as the PUM. So if I trigger the recording with QREC= Plen , max rec lenght, and one2 mode, loop off and set a conditional trig on beat1, the sample will be triggered each time the condition is true so the lenght doesn’t really matter, if it’s a bit shorter then X*bar it’ll loop just fine (because retriggered on the 1st beat) and if it’s a bit longer it’ll cut off. Must avoid to have a note ringing over the bar change though. If I preset the condition to 1:2 given that generally I tend to do 8 bar loops on bass I’ll have the time to change that condition afterwards to 1:4 if ever I just laid down a 16 bar groove.
It’s a matter of rehearsing such a routine.
But for live looping, I think I will stick to PUM’s for now, and try to master them fully, only then I will move on to another chapter of the OT book.
BTW I have run into a PUM weirdness when the other day a buddy dropped by with his drumkit. We started a jam, me on bass, and I attempted to make a PUM recording and having the OT set the tempo (which I had never done before). I somehow got only weird tempo’s like 152.8 when we were in the 120-ish BPM… most probably a user error!
