Did you see any information that indicated that "mma" mode was supposed to

When I read this old thread: <https://lists.nongnu.org/archive/html/fluid-dev/2012-07/msg00024.html>, it sounds implied. It lists GM, GS, XG, and GM2 as bank selection modes, but the modes available are 'gm', 'gs', 'xg', and 'mma'. And assuming MMA = MIDI Manufacturers Association, the group that creates/adopts the General MIDI specs, that leads me to think mma is supposed to be GM2.

If that's not correct, then I apologize.

Good idea to read through the archives..  I also did this and came up with a thread which occurred around the date when the code was checked in for the synth.midi-bank-select option.  I came up with this email in particular from Pedro which describes the MMA mode:

I was aware what MMA stood for, but I was not aware what it actually correlated with as far as its intended effect.  Seems it reflects the ability to specify a 14 bit bank number using bank MSB/LSB messages according to that email.  So its not GM2.  I guess this means a gm2 option could be added.  I'm personally curious though, why you chose GM2 as your MIDI variation of choice?

What part of that Wikipedia article leads you to believe that channels 10
and 11 (9 and 10 as far as FluidSynth is concerned) can be switched to
melodic with GM2?

Under "General requirements":

Simultaneous Melodic Instruments – up to 16 (all Channels)
Simultaneous Percussion Kits – up to 2 (Channel 10/11)

That indicates that channels 10 and 11 (9 and 10) can be switched between melodic and percussion, to give up to 16 melodic channels (0 percussion) or up to 2 percussion channels (14 melodic), depending on your needs.

Now that a re-read that, it does indeed sound like it confirms the ability to switch a percussion channel to be a melodic one.
