Yeah looks like you got it, unfortunately there’s no direct way to automatically stop a recording longer than 64 steps, with rlen max you need to use one2mode and manually enter a stop recording command, qrec is your friend for quantizing the start and stop recording. This can be done with manual sampling as you’ve found but you can also initiate sampling with a one-shot and end it with track+rec, although there is a bug on latest OS where if you start recording with a one-shot you have to press track+rec twice, only once is needed on OS 1.25H.
Long samples can easily be made on Pickups too but you still need a button press to end the recording. There’s some weird avenues to get a set length like already having a set length recording playing and entering PU “replacing” mode, or having a master PU and then slaves with the “Len” parameter, but they all require button presses, extra track, etc…
@pinup57, I haven’t done it but I’m pretty sure you can control the flex recordings same way as pickups using the recorder midi note triggers or the corresponding CC 59/60 values which access the note triggers by CC. There shouldn’t be any more setup required to use flex than PU besides assigning the recorder buffer but you just do that once and save the part, you have to setup pickups too it’s just one more step for flex. If your good with PU’s though probably no need to switch, I use them too all day long (you’ll eventually find some niggles though, there’s a few things I’ve found I must avoid). You also asked about quantize flex record length responding to jkam6033, you can’t automatically but you can use qrec and one2mode just like Pickups…
