Regarding send fx: Just plock the send levels on the supertrack? For example if you want a particular snare hit to go to a reverb you can just plock the step the snare is on.
If you want that reverb as part of the snare sound all the time just resample the snare with that reverb applied to it.
Edit: also regarding your perceived need for „strategies“ to deal with the „clunkiness“ in order to be more effective or something - idk, something about this rubs me the wrong way. It doesn’t sound fun at all.
If I had to do „serious“ music production with tight deadlines and high stakes again (thank god that’s over) I‘d just use my laptop and get to it.
Anyway, what is insanely fun imo is chucking a few hundred oneshots into an eldrum kit, disable velocity to volume in the amp settings and have a giant palette of drum sounds at my fingertips via p-locking velocity to each step - bam, drums solved for an entire project basically, with 7 tracks left to do whatever.
