Slice recording? Call it "slice lock"?
With options for which slices get recorded into, if it's to auto step from one slice to the next after each record trig is active, loop or one shot per track and the option to treat slices as contiguous.
What I mean by contiguous is that every time your record trig gets activated it'll either record into the first active slice and stop or move on to the next one, but if it's set to contiguous it'll record into all active slices, as long as there is space to do so.
The granular possibilities would be mind boggling!
On a more simple level you could for example have a 16 slice loop and arm slices 3,6,9,12 to record live into. It would make it feel like you had a lot more tracks if you're better able to utilize the "empty" space per track.
You could set it up to one shot or auto step and build sample chains this way, which thanks to secret music we all know is an awesome way to use the OT!
For people that wan't more classic style sampling you could devote all your ram to one track, create a slice grid, de-couple it from the sequencer, turn auto step on and then manually trigger the track each time you want to sample and each sample would end up in a new slice ready to be sample chained to infinity.
