Thanks everybody! Pretty much.
The track itself is all arranged and layered in the SP through a very complicated multistep process (which I now think I can refine). I wanted to try not sampling records/YouTube (except for the intro, of course), so I cobbled together some “fake breaks” in Logic and sampled those. Once those were in the SP I sorted out what drums worked well together.
After I figured out what drums I wanted to use, I sampled other stuff, and layered things on top of the drums using the resample method, and then I finally I made a bunch of patterns out of those resampled bits.
I then used the song mode/pattern chain to come up with the arrangement/sequencing, and once I had something I liked I resampled that into a single sample using live effects (and Bus 3-4). Then I went back and used resample again to do live overdubs on top of that to get the final track.
Finally I exported the final track to the computer and just used a limiter to boost the level.
I didn’t know what I was doing and had to come up with the workflow on the fly so I made a ton of mistakes along the way and had to change direction at times and also do a lot of different takes.
More than making a track though, this was about experimenting with things on the SP to learn all the functions. That mindset made it a lot easier to suck up all the work I lost along the way (and to come to terms with some of the less than perfect results).
