It was written as
- experiment with just intonation (music)
- event driven state machines demo (programming)
- make sure you have
libasound2-devandlibx11-devinstalled /opt/zig-0.12/zig build

Legend
b - key on the keyboard
SO - note/pitch (G in usual notation for this case)
3:2 - frequency ratio (pure/just fifth for this case)
By default xjiss uses /dev/snd/pcmC0D0p playback device, which might not present
on some particular system. In this case do the following
- find out which playback devices you have:
$ ls -l /dev/snd | grep p$
crw-rw----+ 1 root audio 116, 3 Nov 30 20:08 pcmC0D3p
crw-rw----+ 1 root audio 116, 6 Nov 30 20:21 pcmC1D0p
- run
xjisswith environment variableXJIS_PLAYBACK_DEVICEset:
XJIS_PLAYBACK_DEVICE="plughw:0,3" xjiss s 3333
XJIS_PLAYBACK_DEVICE="plughw:1,0" xjiss s 3333
plughw:0,3 corresponds to pcmC0D3p, plughw:1,0 to pcmC1D0p and so on.
