hmm… now as you say it… yes… The Lo-cut-switch was accidentally on 
some words to the “Band” and the Recording stuff:
We’re not really planning and arranging songs. Usually I come up with a Synth-/Piano-Pattern and then there’s our drummer and the E-bassist and we just jam along. Sometimes there’s also a singer.
Bass, Singer and Me are going into a Behringer Eurorack MX1602 which is connected to a McCrypt power amplifier and some pretty old Dynacord boxes. I have to say that I don’t know who has bought the power amplyfier and the Loudspeakers. The room we’re playing in belongs to noone, everyone can play there.
The Recording is done with a Edirol R-44 I’ve won once. The drums are recorded with some cheapo Shure Mic, Bass and Myself are routed to the 2 Aux-Busses, which then go to the R-44, and as the mixer has only 2 Aux-Busses, the singer has to sing into 2 Mics when he wants to be heard on PA and on the Recording
.
As you can see, it’s pretty chaotic. But it works and it is a lot of fun.
As I have to unplug, pack, carry, unpack, replug, unplug, pack, carry, unpack and replug all my equipment when we’re practicing, I really only take some kind of “minimal-setup” with me.
That includes my mixer, the R-44, a Roland SH-201 and a Roland U-220 for piano- and string-samples and stuff like that.
So Auto-panning of some high-freq-strings is not really doable 
After the sessions I just open the files in Audacity, mix them roughly and upload them.
Thank you for your tips. Next time I’ll take care of the Lo-cut switch and play around with the EQs a bit.
