Recently I was doing some of that with an orchestral percussionist. Here’s a rundown of what I was doing.
I have three or four OT “sampler” tracks pre-set with certain playback and filter parameters, LFO actions, and effects.
All tracks have re-trig set either very high, or all the way to INF. After triggering a fresh sample, I’ll play with the re-trig time in real time.
Some of the tracks have the slider controlling the start point of the sample, ranging 1-127. With others, I control the start time continuously.
I’d sample him into a track for maybe four bars, get an interesting loop going, then select the next track and sample him again. In practice, I never had more than two tracks going at once; two alone rendered such interesting results, that between the OT and him going nuts with his own effect chain, things could get pretty insane. (Not that that’s a bad thing…)
I manually synced the tempo to him, periodically re-applying the manual Tap function if things got too far off.
The only real challenge was performing the Record action in a way that didn’t have a tiny bit of space at the front. If that happens, you can just set the start time knob to 1, or even open the editor and change the start time there, but with a little practice you can avoid all that.
Here’s an edit of what we were doing.

If you listen, bear in mind that you’re also hearing a lot of Eventide processor on his rig, and on the OT. There’s also some MD, Jomox kick, and Virus.
We went on like this for almost two hours, it was Thanksgiving Eve and we were in serious party mode
