Late Stage Music Player

Granted I do not much listen to music these years—or too much if I'm obsessing over something like the second section of a Menuet, but that's not really what most would call listening to music. If I want some background noise there is the "music player"

    #!/bin/sh
    setvol 40 /mpv 100
    cd ~/share/video/aquatic && exec mpv --shuffle --no-video .

and that directory has various ambient schlock linked to from somewhere, probably it was

as "Dronny Darko" was pretty easy to search for. setvol(1) is a pretty obvious wrapper around sndioctl(1) on OpenBSD, except it takes 0..100 for the volume instead of the 0.0 to 1.0 that sndioctl(1) wants, and is easier for me to type.

    $ sndioctl
    input.level=0.600
    input.mute=0
    output.level=0.549
    output.mute=0
    server.device=0
    app/aucat0.level=1.000
    app/audacit0.level=1.000
    app/fluidsy0.level=1.000
    app/lmms0.level=1.000
    app/midipla0.level=1.000
    app/mpv0.level=1.000
    app/play0.level=1.000

Otherwise play(1) from the sox package sometimes gets used, but that lacks the easy spacebar to pause the playback like mpv(1) has. midiplay(1) is a custom fluidsynth wrapper that defaults to the generaluser-gs-soundfont; that and most of the rest are for music production.

My life would probably be easier if I didn't pick hard to play end-blown flutes.
