## 1st: apply patch below, fix up any merge-conflicts and git commit the result.
## 2nd run (after commiting the new version): re-create the patch to upstream & amend:
# git diff -R libs/fluidsynth/ > tools/fluid-patches/ardour_fluidsynth.diff
#exit
patch -p1 < tools/fluid-patches/ardour_fluidsynth.diff
