If you weren't aware, BMI/ASCAP/SESAC are payments for "performance rights" (radio, tv, restaurants airplay) and not
mechanicals royalties (physical CDs and digital downloads) Therefore, the bigger money would probably be any amounts you can negotiate from an entity to directly license
your instrumental composition. E.g. you sell a license to Toyota to use your rock instrumental in their car commercial for $15000. That $15k is going to be the only money you'll likely see. Any income stream from BMI/ASCAP "performances" will not be significant because of the limited public appeal of the rock instrumental genre. On the other hand, if it was a top-40 rock pop song with vocals, the BMI/ASCAP checks could exceed the money from direct licensing or mechanicals.
Anyway, the Moses Avalon blog had several posts describing the differences between ASCAP and BMI: Why You Should Think Twice Before Joining ASCAP, BMI or SESAC Why You Should Think Twice Before Joining ASCAP, BMI or SESAC - Part II: Non-Profit Nonsense Who Pays More?
