smhkd
smhkd (Simple MIDI hotkontrol daemon) is a daemon that reacts to MIDI events by executing commands.
It's inspired by sxhkd, but handles ALSA MIDI events rather than X events.
Current Status
smhkd is still in design phase and not yet ready for mainstream usage.
At the moment, and at the moment only, it reads a configuration file in ~/.config/smhkd/smhkdrc.json
, which looks like this:
{
"28:0": {
"0": "pactl set-sink-volume @DEFAULT_SINK@ $VALUE%",
"32": "pactl set-sink-volume @DEFAULT_SINK@ 100%",
"48": "pactl set-sink-volume @DEFAULT_SINK@ 30%",
"64": "pactl set-sink-volume @DEFAULT_SINK@ 0%"
},
"129:0": {
"1": "pactl set-sink-volume @DEFAULT_SINK@ $VALUE%",
"67": "pactl set-sink-volume @DEFAULT_SINK@ 100%",
"66": "pactl set-sink-volume @DEFAULT_SINK@ 30%",
"64": "pactl set-sink-volume @DEFAULT_SINK@ 0%"
}
}
and it listens to each pair of client and port (28:0
, 129:0
and so on…) for MIDI events.
Every time it receives an event, it runs the command associated with the controller ID (if any). Occurences of $VALUE
in that command are replaced with the value of the event.
Keep in mind that this configuration format is only temporary and will ultimately be replaced with something more similar to what sxhkd uses. There is no plan to provide backward compatibility with JSON or even a migration path when than happens.
