chicken scheme on OpenBSD using portmidi C lib via ffi.

(I have a fluidsynth instance waiting in the background
to send some midi events to.)

#openbsd #chicken #midi #fluidsynth

$ make
chicken-csc -s -J -I/usr/local/include -L -lportmidi midi.scm midic.c
chicken-csc -I/usr/local/include -L -lportmidi main.scm -o main.exe
$ ./main.exe

@pkw Nice! sndio is pretty great too if you want to go full OpenBSD. I did a similar sort of thing a while ago with sndio & Guile on OpenBSD. I believe sndio has MIDI too :)

Oh that's cool! I love that OpenBSD has a pretty good and
updated sound stack, including midi :)

Like bluetooth was kicked out, but MIDI is fine :)

I always look to SDL to do this kind of stuff, because I'm
pilled to make code that is ostensibly portable.
Like if I ever made a game I'd feel obligated to make
it work on linux.

@pkw oh yeah, portable is definitely the best way to go (and SDL is magic). I'd probably just use Debian stable if I wasn't so stubborn :)

I'm quite happy making little programs exclusively for myself (and potentially any other OBSD weirdos)
