Topic: Trying to Setup MIDI Commands and Need Help Desperately

Okay, I am losing my mind here. I am certainly a newb, but I just don't know what I'm missing as I have tried and researched everything.

I recently purchased a Rodecaster Pro II for streaming but I still use my RME Babyface Pro for referencing, especially on monitors, because the playback bitrate is much higher and noticeably clearer.

Nevertheless, I simply want to set a fader on my Rodecaster Pro II to adjust speaker volume. It seems as if the Rodecaster Pro II uses a typical Mackie protocol, but for the life of me, I cannot figure out what channel/settings are for the Speaker output on my Totalmix. I have enabled Midi, I have set the MIDI device correctly, but the default MIDI settings do not work and since Totalmix doesn't have an "autofind" feature for the settings, I need to know what the type is (Note or CC), channel, and 'on' value is supposed to be.

Can anyone assist?
