Hi Dextroze,
I have a RME Babyface Pro, too.
PA FOH gets a stereo sum, only. With many synths and samplers and different sound characters coming out of them, different for each part within a song, there would be no chance for a mixer to find a proper balance between them in time, anyway. Balance and EQing of the sounds need to by checked during setting up at home, and then during band rehearsals. Fine tunig after a few shows, and then don’t touch anymore.
IMHO overall balance of the band instruments and EQing depending on the PA and venue is part of the job of the mixer, but not the internal balance of my sounds.
Small recommendation for adjusting sound levels:
As a final plug in the stereo sum before it is routed to the analog outs I always use the same preset of this compressor/limiter plug-in in every rackspace:
In low-latency mode it has almost no extra latency (0,12 ms = 3cm distance in air), and yet, almost no distortion even at quite heavy compression and onset of peak limiting.
I adjust any sound level (except very calm sounds) until I see some compression and onset of peak limiting on the meters. So I offer the PA the same sound level for any sound, without any significant overshoots. Overshoots typically forces the mixer to pull your fader down, and then to forget to pull it up, again.
Here’s my preset, tested to work fine for this purpose, can be imported in text format:
