[ABANDONED] Anyone know how to set OpenMPT levels on Linux?

[Neigdoig]

I ask because my first post had the assumption that I could get Fluidsynth to work on the Linux build of SRB2 2.2.10 on Mint 21. Unfortunately, it was pointed out that it's only in the Windows version, which frustrated me a bit (which also brought about a controversial post on the forms, due to how I worded it, which was quite honest).

I'd like to know how I can set OpenMPT levels on Linux to work with SRB2, since the instruments are quite unbalanced in terms of volume, since there might not be MIDI soundfont support for Linux anytime soon.
