i used a mk4 disting for this exact purpose for years, and it works a treat but it’s not without its caveats…
the longer the sample length is of the loop, the more processor intensive it becomes (as one might expect,) so if you try and do anything fancy to it (reverse, scrub, speed) other than just playing it back, it could get weird. if you drop a super long sample onto the card and select the algo with reverse, the module creates a whole new reversed version of the file the first time you do this, and if its big, it takes quite a while to do that…so def don’t try that live.
also the dual playback mode is nice. similar to having two plays, but with half the power consumption and more options.
