Okay, that's pretty neat. I've been thinking about doing something like this to control MC. 
Thanks! They are a bit of a pain. I can only assign key presses, so I've had to painfully assign keyboard shortcuts one by one in Mint to it. I'll share the script that turns those into commands on request.
The keypress is assigned to the memory of the board, there isn't currently a program that is capable of this in linux for mine so I've had to use a VM and windows. The variety of different boards out there is large, and they work differently. Some are ok, mine will be up and running soon hopefully. It was only 25 quid.
The browser volume control isn't very functional as it opens a new input-sink for each vid being played. The buttons I've got next and previous track, and switch audio output device on too.
I'd like to be able to set seq from sort and assign that to a button, but haven't been able to work out how as yet.
