Soundfont

Soundfont files can be found at various places on the Internet.

Soundfont files help convert MIDI into sounds with suitable hardware or more likely these days software such as fluidsynth or LMMS (among many others; I'm mostly limited to what I can install on OpenBSD). Soundfont files are RIFF format, so EXIF tools may show header details.

Parsing the soundfont for what instruments it has and in what banks requires some time spent pouring over the soundfont specification and various "ah hah!" moments. This otherwise generally requires quite a lot of slow clicking around in some gooey (GUI) interface, which isn't very greppable, and is generally hard to save somewhere for reference. Therefore,

    [ patch_change   =>  0, 0, 42    ], # otherwise control_change ignored
