RME Fireface - Stand-Alone MIDI Control

Hello,

I have been using my Fireface UC in stand-alone mode, i.e. without a computer, and it works well as a multitrack router.

However, I’d now like to control basic mixer features of TotalMix via a MIDI controller - also outside of the box. Eseentially, I would just need to mute/unmute tracks/channels.

Has anybody done this among the good people on this forum?

If yes, is it possible to chose which MIDI messages (CC or note or else) of the controller will control any given feature in TotalMix?

Sorry if this is a very specific question. I just hope somebody has already tried that in the past.
