Here's a rough version for you.
I didn't understand why you had 3 duplicate tracks for the bass and 2 for the rhodes?
Anyway, I deleted those from this version as they seemed to be identical and not adding anything to the mix or arrangement. I simply used the sends from the tracks to create sub mixes.
Now, importantly... The Audio and Inst channels that have been 'sent' to various Bus/Aux channels are set to 'No Output'.
To listen to one sub mix ONLY (and not the entire combination of all Aux channels!) SOLO that Aux Channel.
To quickly switch to another sub mix:
Option-click the Solo button of another Aux Channel. This is the best way to switch between mixes on the fly.
Nice track by the way :)
