Dosbox-X x86 SDL2 incorrect MIDI sound through Fluidsynth

[pablokks]

Describe the bug

I like using SDL2 x86 version of Dosbox-X cause it supports joystick output (in SDL1s I see joystick being disabled in key mapper) and glide wrappers like nGlide (my understating is that only x86 versions supports it). However MIDI soundfonts through Fluidsynth sound incorrect in this particular build. They sound correct in SDL1 x64, SDL1 x86 and SDL2 x64 but for whatever reason in SDL2 x86 they sound out of place and I have tested couple of different soundfonts. It would be nice to not need to juggle between different builds but currently I cannot use SDL2 x86 with games with MIDI soundtrack cause it just sounds bad. Appreciate the help.

Steps to reproduce the behaviour

1. Run SDL2 x86
2. Set Fluidsynth as MIDI device
3. Create a path to soundfont
4. Run a game with MIDI set up (e.g. Doom)

MinGW SDL2 32-bit seems to work better.

I totally forgot about those and yes I can report that all MinGW, including SDL2 32-bit, seem to be working fine with soundfonts. So it's just standard SDL2 32-bit that has issue, so for now I will be using MinGW SDL2 x86, although forgive my ignorance I am not sure what MinGW provides.

INSTALL.md recommends as default Visual Studio and SDL1, while recently there are many issues where the solution is to use MinGW or SDL2. Maybe that should be changed?

[maron2000]

Another workaround is to use external midi synth such as VirtualMidiSynth.
With this, VS x86 SDL2 can also be an option.
There are sometimes compiler/SDL independent bugs so it's difficult to recommend which one as standard, but it is true that many bugs peculiar to MinGW version got fixed recently.
