It’s totally on my radar, as that would pretty much replace Gut Glove for my own personal usage in this kind of setup, even if it is just a stripped back version.
I think softcut and karma~ pretty much do the same stuff (though I think some of the interpolation stuff was disabled at some point, but not sure if that was only for the norns-mlr), so that should be fine enough even if it is a quite different paradigm/approach.
The hard part comes in the mapping part. I would say 80-90% of the Cut Glove patch is mapping/scaling/routing of numbers with oodles of edge cases (i.e. what happens if you release play while holding record etc…).
I think long-long term I’ll have norns-y versions of most of my apps (Cut Glove, Chocolate Grinder, and even as much of The Party Van as I can fit), along with more stand-alone versions of all the fx (possibly combined into a “pedalboard”-type script where you can load diff effects.
edit:
I also need to check to see if the xbox360 (and/or xbox one) controller show up the norns as a generic HID device, or if they need another layer. (on my mac I have a driver installed for the 360 controller, but the one works via the generic bluetooth pairing).
