@guitartone: the change in sound is so huge that it seems that a whole eq/cab section has been changed, but i didn't.
Tomorrow i'll try to move profiles keeping the cabinet section locked and viceversa.

Difference between 2 and 3 is clear and it does sound like the cab has changed - I wonder if the change to the next profile preloads the cab of that profile (in code) and doesn't release it if you switch back to the first profile. What happens if you put the same profile next to itself and do the switch then? What happens if you put two profiles with the same cab next to each other and do the switching around then?

I'd test it myself but I'm not going to 1.04 until we have the issue ironed out and I don't have the problem.

Unfortunately it's not a cab change. I have the same problem when I switch between two rigs using the same cab. On start up Rig 1 (normal sound) then switch to Rig 2 (same cab as Rig 1) back to Rig 1 - sound changed - more scooped and more presence/fizziness and also slight increase of volume (about 1 db). For now my workaround is to engange a master eq where I cut a little bit of presence and increase midrange by about 0.5 - 1. Works ok until the fix.

Besides this ugly bug 1.06 seems to be really cool and stable I think. So, I hope they manage to fix that soon and then we are all rocking again.

Here is an audio sample (recorded via the SPDif out of the KPA):

Audio1
Rig1, after KPA bootet up
(also, this is exactly how this rig sounded with FW 1.0.4)

Audio2
Rig1, after switching to another rig and back to rig1.
(also, this is how the rig sounded in FW 1.0.5)

Same guitar, same pickup, same cable, same pic, same player - you get the picture
Sorry for the lame playing.

Do you hear a difference? I definitely do.
Sorry for the noise - I have the noisegate disabled, and this is a highgain rig


Summing up: FW 1.0.6 sounds like FW 1.0.4 when the KPA boots up - and then goes back sounding like FW 1.0.5. when you switch rigs.

Hi, just an advice to be more precise in the comparison. I clearly ear differences between the two tracks, but it is very important they sound EXACT the same from the beginning, so, even if you use same guitar, same pickup etc... but you are playing a different TAKE, the sound will be different!
Can you (or others too) next times use a looper with the same take? It will be in this case definitively a REAL comparison with no more doubts!
Try it... believe me...

How's the latency compared to 1.0.5?

UPDATED
I miss a substraction in previous ONE and I did some more accurate measurements, here you have the results...

The conclusion is that latency is a little worst then in the 1.0.5, but still good compared to 1.0.4.

Here you have the data:
1.0.4 latency was about 207 samples (4,7 ms);
1.0.5 latency was about 107 samples (2,43 ms) (and THE BEST TILL NOW reached and that really meets the specifications);
1.0.6 latency was about 134 samples (3,04 ms)...

I try before and after System restart, and the latency is exactly the same, so no need for that.
Also, indipendently from the measurements method (anyone has its), I use always the same for every KPA version, so at least the comparison from them is totally effective.

Did anyone measure it? I believe that on latency the Kemper Profiling Amp still must find his stability
Also I noticed little difference latency depending on the chain effects used (with others MultiEffect consolle this not happened).
For example I measure that in 1.0.6 if all the chain is off (also Stack module off) latency is 2,6 ms.

Thanks for the tip, Maurizio. That's very true. I tried playing something similar and I think the sample I did was good enough to demonstrate the difference, but yes, only a looped signal will be a truly 100% accurate comparison. Only prob is, I don't have a looper around.

Ok, I'm an idiot! Thanks, got it now!
