I know. Presently, I mix down to stereo, copy the whole folder to a new one, rename it consecutively, and then clear the mono tracks…

One more suggestion.
I asked whether this is possible in the tech forum, but I’m thinking it’s not currently an option, otherwise it would have been mentioned in the manual…

The ability to copy a stereo mixdown track to another loop.

This isn’t something that would find much use in a live situation, but it certainly would in studio circumstances, and especially for people who, like me, approach music through improvisation.
I start by playing a rhythm on my Korg Wavedrum or Roland Handsonic, and then just keep on adding different percussion layers (after which I would add VSTi pads and soundscapes in my DAW). Having the feature I suggested would allow me to ultimately import every single separate percussion layer into my DAW for further processing and composing of the track.

What I suggested is, I guess, doable via a computer and USB, but it would be much less of a hassle and more productive if it could be done on the looper itself.

I’m a layman, but I still think it’s something that should be easy to implement in a firmware update…
