Thanks for your hints. I was able to get a good sounding wah sound.
The remaining problem is simply the wah pedal on the Behringer FCB 1010.
I calibrated it (again) but it does not show any reaction for the first 50% of the pedal range.
I do use the Uno4Kemper chip but the different curves do not show any improvement.
How do you use your 1010 wah pedal? What curve?
@db9091: It sounds great at home I fully agree. But once the band kicks in (drummer, bass, 2nd guitar) it does not sound anymore as good as a 4x12.
That's the only negative aspect of my setup. As I said...I carefully compared all pros/cons and the Kemper is a clear winner.
Just to give an update here. After many weeks of searching, reading and experimenting I finally decided last night after rehearsal to take my old Engl Raider and massive pedalboard back home.
Only the Kemper with the DXR 10 is used now for reheasals, recording and (hopefully) gigs (have not gigged with this band yet).
Why?
1) I love to tweak sounds and effects at home
I just take my Kemper back home (in the wonderful green fishermans bag 
) and tweak sounds there. I am using a scond DXR at home...so I have an identical setup.
For rehearsal I just plug in the Kemper and all the sounds are just there. Maybe a little (10sec) tweaking to adjust effects to full band volume.
For just effects tweaking (when I already decided for the amp sound) even tweaking at night using good headphones works well.
2) We do record all rehearsals...so everybody can listen to it at home
Obviously this is where the Kemper shines. I run the main out into the mixer and we record all tracks separately. I even started to record the dry guitar signal using direct out. Wonderful!
3) Recordings
We started to record our songs for CD/Website/Demos etc.
I just take the Kemper to the studio. Minor tweaking only (mainly reducing/deleting effects that will be added during the final mix) and I have the exact same sound as always. No noise, hiss or other issues.
4) Amp in the room feeling
No. You do not get the same feeling playing it with the band compared to my previous setup (Engl Raider 100 + 2x12 cabinet = 3x12).
There is just less air moved. Does not feel as intense anymore.
But...I always had to play at very high volumes to make the Engl sound good. So...in reality it just felt intense but did not sound to good.
With the DXR the sound is excellent but when the band kicks in it does not sound as good I wished. But I can clearly hear myself from any position in the room and my band mates agree on that fact and do like the sound.
As this is just my personal monitor the main objective is that I can hear what I am playing. And this is the case!
Summary:
When I take all use scenarios and pros/cons into account....
....the Kemper clearly wins. It made my live much easier and is such a pleasure to play.
Do I sell my tube amps now? Mmhhh...not now....but I will profile them and then we'll see 
Thanks nightlight! Will try it out!
Thanks Michael!
I am not giving up.....I am sure I can find the right wah tone.
I am using the amp factory AC30 amps as my main sound and need a good sounding wah for the "cranked" tones.
I am looking forward to the user community experiences. Maybe part of it is related to the Behringer wah pedal (even calibrated perfectly that thing is not full range...).

I have tried for hours but could not find a good wah setting. This might be partially caused by the shitty wah pedal on the Behringer 1010 but is mainly a sittings issue.
I tried pre and post distortion. All wah pedals and pre-sets....but they all sound worse than my Dunlop Wah with my tube amp.
I really would like to avoid using a real wah pedal again...my setup is so organized now...
What have you experienced? What are recommended settings? The wah should be used for crunched to distorted amps (no metal...just blues to rock sounds).
Thanks!
What guitar (acoustic vs. electric), amps (clean vs. distorted), music are you playing?
I can't complain about having a thin sound with my DXR. Actually my band mates thought it is too thick....so I use the 100Hz filter on the DXR during rehearsal...that fixes it.
Thanks! Exactly what I needed!
I am looking for a rig that gives me the tone of the SOLO part for AC/DCs "The Jack" from the live album "If you want blood...."

Starting at 2 minutes....
My guitars for this song: Düsenberg Starplayer TV Mike Campell or Gibson Les Paul Custom
I am in the process of doing this as well. I'll keep just the ones I need for my band.
Of course I'm trying out new ones regularly but I browse trough them with the Rig Manager....so easy to check new rigs quickly w/o copying them to the Kemper permanently.
I know this is highly dependent on personal style and type of music played but I'd like to know what worked well (or not so well) for you.
I started to program all of my songs as Performances to be re-called/controlled via the Behringer 1010 with Uno for Kemper and wasn't sure what approach to take.
Do you:
1) Program each song as a performance and just switch slots for various parts of the song (intro, solo, verse etc.)
2) Just select rigs with the slots and control your sound by switching effects on and off?
3) Something else...
What works best for you live?
Rainer
Have fun with it David!
Has anybody done live re-amping using 2 Kempers?
That's it, exactly! I can not hear any tonal difference. It's just quieter now 
That's what I did before to get the noise under control...I had set it to -8db.
With my new XLR Adapter strategy I can turn the DXR all the way to the right ......still no noise!
No Ingolf,
you care about your band mates!
Very nice of you 
Rainer
What do you mean. It's just connected like a normal monitor. Instead of a instrument cable I now use a XLR cable connected with the Neutrik Adapter.
Input sensitivity (Clean sense...is that what you mean?) has nothing to do with it.
Update: Got my second Yamaha DXR 10 today!
One will stay at the rehearsal room. One is at home. I am just carrying the Kemper and the FCB 1010 foot controller back and forth. Soooo nice!
Update: My order arrived today.
Now I use:
Monitor out on Kemper > Neutrik Adapter from mono jack to male XLR > 3 meter XLR cabel > Yamaha DXR 10 XLR input.
SILENCE! Absolutely no noises (except for the fan and a very silent hiss)
So...if you have to use the monitor out (or direct out) and normal signal/instrument cables create too much noise...try this! It works!
Have not gigged with it yet. But used that firmware version for hours with a 1010 and Uno4Kemper chip. No issues at all!
