The packages `freepats` and `fluid-3` are 31.9 and 13.9 MiB respectively. I think that the best solution would be to include them as inputs to packages that use sdl-mixer to actually play MIDI files. I did so for CorsixTH (patch submitted), which was also the reason for the sdl-mixer patches. :) Thank you for the feedback!

If this is incorrect, just let me know! Thanks, Chris
Hi, these patches improve sdl- and sdl2-mixer: fix dependencies and configure flags that changed between the two versions, and enable support for fluidsynth and opus libraries. I tested several dependent packages, and everything seems to work OK. The MIDI backends need additional runtime configuration. Fluidsynth requires a soundfont to be installed and specified when running a program that uses sdl-mixer, e.g.: SDL_SOUNDFONTS=/gnu/store/…-fluid-3-2.1/share/soundfonts/FluidR3Mono_GM.sf3 If this is not set, the bundled timidity backend is used, which can use the freepats samples. Configuration must be specified since only files under /etc are checked by default, e.g.: TIMIDITY_CFG=/gnu/store/…-freepats-20060219/share/freepats/freepats.cfg I’m not sure if and how default values for these vars can be specified for all programs using sdl-mixer, and I would prefer to leave the choice of backend to the user anyway. However, we should probably document them somewhere. Would a comment be enough? Dependent packages can then wrap binaries to set required paths if needed. Alternatively we can add freepats and/or fluid as inputs to sdl(2)-mixer and patch the source to look for them in the store. Thanks!
