This keymap works with midi2vol: linux version https://github.com/jesusvallejo/Midi2Vol-Linux
and windows version https://github.com/jesusvallejo/Midi2Vol
Enables the user to change the volume on the host computer if running midi2vol software.
Example to extend usability is provided check VLC in: enum custom_keycodes {} and bool process_record_user(uint16_t keycode, keyrecord_t *record) {}
Remember to give allways the new volume control a hex value not used by other volume control,
and add it to the midi2vol software.
Check respective midi2vol readme on how to do so.In linux change config.json,in windows you can use configuration option.
A compiled version of this keymap is provided in here: https://github.com/jesusvallejo/nanokeymaps/
