I am definitely interested in this subject 
The two avenues you guys described apply to me at the moment:
-
Trying to learn/internalize strategies, or building blocks rather than complete patches, and
-
Recording audio of just extended improvisation that then can be carved down into something self-contained.
I find that I lean towards 1. more frequently, as I tend to think of modular as an “in the moment” instrument. But, when it comes to performing live, I am trying to figure out a way to “notate” certain aspects of the piece. A general momentum of particular segments, or textures, or levels of intensity etc. So, rather open-ended ideas that would need to be interpreted on the spot.
BUT
I also have attempted to “write down” patches that were developed for particular performances. I posted this image on the old forum, but it probably belongs here:
