I tried to find out the same thing (which library is being used by
Qsynth). I noticed the following text among the messages in Qsynth
(click the "Messages" button to see them):
fluidsynth: warning: Instrument not found on channel 9 [bank=128
prog=9], substituted [bank=128 prog=0]
I decided to change the word "substituted" to something else so that I
would be able to tell from these messages that the new library was being
used. The line I changed was in *src/synth/fluid_synth.c*, line 1,922.
In my case, I changed the word "substituted" to "pooped". So now Qsynth
shows this message when it's using the 1.1.6 library:
fluidsynth: warning: Instrument not found on channel 9 [bank=128
prog=9], pooped [bank=128 prog=0]
