Perhaps you are talking about GM, GS mode where bank# is LSB. Now, just think
XG uses MSB instead of LSB. MSB=128 is drum in XG, as well as MSB=126,
MSB=120. No difference in that regard (the number 128). The only difference
is that it is sent via CC#0. So for MMA-calculation (basically convert to
decimal number the combination of MSB, LSB), MSB need to be shifted 7 bits
further to the left. And this is done only for XG bank-select style in my
code. I hope it help clear any confusion.

Hmmm... ??? I'll take another look on my side. Again, can you try with:
fluidsynth -o synth.midi-bank-select=xg
if and when you get a chance.
