I’m using Studio One as well and have a setup where I’m tracking the OT and my entire mixer’s direct outputs and I’m doing this for both multi track recordings (usually done in the start - printing the basics from OT Arranger) and individual tracks such as syncing along to those initial multi tracks.
I find that using Studio One with a Presonus interface (using Studio 192 mobile) is the first thing to take care of. Any of the Presonus interfaces allowing for the HW ”zero”- latency mode is the key. This actually gives me the feeling of just recording into a tape recorder - being able to play for example the upright piano without worrying about the drift.
Another massively important device for the clock sync to allow for individual tracks to be added on top of the ”foundation” is the Expert Sleepers USAMO. It’s using one of the audio outs of your interface instead of relying on midi (for that part) and then you’re able to fine tune as well as select what to actually send out (from the USAMO to OT there’s regular MIDI).
I’m finding that I can run the OT looped to a specific section in Studio One over and over again without drifting - allowing me to perform multiple takes and actually comp them together if needed.
I’ve just done it this way with the USAMO for a few months but it’s been solid - very much recommended!
