/*

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/
