I wish there was a way to have sends be saved as part of a musicloop.
For example, say you have your favorite drum sample library, and you routed it all out into Studio One, did all your processing, etc. etc. If you send -7 db of your snare to a parallel compression send, and then save that as a musicloop, Studio One recognizes that you had the parallel compression send, but doesn't remember that you had -7 db of your snare sent to that bus.
I feel like this is a limitation that could apply to endless other uses outside of drums, and could open up a ton more possibilities for sound design and mixing/songwriting.
