Trying to use gravis ultrasound Propatches lite 1.61 that come with GUS dos drivers with gus emulation in zdoom, and timidity (SDL_mixer version); in Linux. http://vogons.zetafleet.com/viewtopic.php?t=16974

Get bad distortion and what seems like clipping with bassdrums (not exactly sure if it's clipping but it's awful) and other noises. Using EAWPATS via timidity (SDL_mixer) work but I really prefer Propatches lite or standard GUS driver pats since I used both with a gravis ultrasound and K6 back in the day and it sounds so much better (thankfully they can be heard properly with dosbox); EAWPATS has a very modern, clean and artificial sound. Chocolate-doom, prboom-plus and eternity have this problem in linux (using Slackware64 14) though it's really sdl_mixer's fault.

Funnily enough zdoom has no problem with timidity in linux (I'm guessing it uses Timidity++ instead of sdl_mixer's timidity) but when I point to the ULTRASND/MIDI folder via zdoom.ini and choose gus midi for music, the distortion comes right back!

I'm using the most basic .cfg in the ULTRASND/MIDI folder (propatches lite 1.61). This is what it looks like:

Any help is awesome!

Note:
Haven't seen other source ports of Doom use timidity++ server; they always have SDL_mixer and that stuff sucks (at least for linux midi). Chocolate-doom could really use something like what dosbox has (including other source ports). Going to try and patch chocolate-doom, eternity and whatever else to use timidity++ server but I'm a real piece of work with coding. Can compile stuff from source code, edit scripts and apply patches but don't know if adding new midi output to a doom source port is too much. Maybe one of you that programs (Quasar) can say how difficult this is for a noob.

ZDoom's GUS emulator is based on the old TiMidity (not TM++) and modified based on the source code of the GUS drivers. The TiMidity++ option feeds MIDI data to an external process. In any case, ZDoom never uses SDL_Mixer, even on Linux. The sound system all goes through FMOD Ex.

Great job on zdoom; props to the crew. Unfortunately sdl_mixer hasn't updated it's midi function (uses old timidity). Thought I'd avoid all problems with hardware midi (on linux) but there's still plenty of problems with software midi due to sdl_mixer using old timidity. Don't think Windows users are happy either with sdl_mixer; think you need a seperate process to change volume levels due to Windows mixer.

Is it difficult to implement different midi code in chocolate-doom or other source ports (using something like what dosbox or eduke32 uses; maybe fmod since it has other great features)?
