Thanks - I'm the singer.
This week I'm going to run the main mix through Aux 6 and record with the main bus. Still a blind recording, but done every week something will turn out at some point. After years of recording with my Presonus StudioLive, I've gotten decent simple live mixes. Except for break music, the PA is running mono anyway, so going off the Aux won't really be any different. Dedicating the main bus for recording will allow adjustments to be made that only affect the recording and not FOH. Adjustments I'd make....
1 - Panning guitar and keys slightly to opposite sides
2 - Possibly run my vocals in stereo so the harmonies are panned (I use a VoiceLive2)
3 - The bass is the only instrument with an amp on stage. The smaller the venue the more the amp carries into the room. This is why the bass is under-mixed on the sample recordings.
4 - I'm pretty sure the recording is post EQ, which isn't a good thing since the main EQ is used to adjust for your speakers and the room. A benefit of recording the show without a master EQ is to listen back to the recording to see if any of the instruments aren't EQ'd well. If not, you make adjustments to the channel strip. After a few shows you should be able to get a recording that sounds good EQ wise. Once you've done that don't mess with the channel strip EQ's any more. Use the main EQ to tune the sound to the room.
5 - The kick is too loud in this mix. The thump is great in a live dance party situation, but not so good on a recording
6 - Since most backing vocals are done with my harmonizer, for a cleaner FOH mix, I like to gate the other vocal mics. Sometimes I'll take the "toasting" microphone and leave it open as a room mic. This will give the recording a more live feel and can be controlled with the channel strip to not be too much. I leave this out of the FOH mix and just print it to the recording
