Hi @Blindsmyth, sorry for the late answer.
Yes, I think it's possible, it's certainly easier than doing it in real time 
I see four ways to do this :
- record with your favorite sound editor, then slice by hand : yours eyes are the best algorithm. I think it's not your goal ;
- record with your favorite sound editor and use it to slice the recorded sample : some good editors have a slicer plugin ;
- record with axoloti, then press a button to slice the recorded sample, and play with slices : I think it's your goal ;
- record and slice in real time. Today, demo patch have 4 channels, but you cant increase this by adding beatslicer objects. It's not your proposal but, I think, it works the same ways, no ?
But I find it interesting to code the point 3 !
Not now, I'm going on vacation three weeks, without computer..., but with my axoloti core, a smartphone battery and an STM32F429I-DISCOVERY board to control the axoloti board ! (touch screen and midi usb device configuration).
I will not forget to watch this on my return.
