clicks and crackles when switching rigs

Are you on firmware 2.0 ?

Yep CK I'm on Firmware 2.0

V2.00 here. CK, I'm also getting crackling noise here. I find that if it happens it'll happen from first bootup. If it doesn't happen straight away then doesn't happen at all. For me it seems completely random. I went 3 nights without any problems then the following night it crackled for all profiles I tried. I have tried lowering clean sense, profile volume, amp etc. Doesn't help.

Installed the new uno4kemper chip in my FCB today and this has cured my clicks a little. My stock FCB used to make the kemper click if you say pressed switch 1 if you were to press 1 again you would get a click. But with the Uno4kemper chip it doesn't. Unfortunately my clicks when you change rigs is still there

No - not on my rack version (without power amp)

New update

Had some
time tonight to try to narrow my popping problem down.

I´m running
the Beta firmware.

If I don´t
use the stereo-loop (got a ErnieBall 25K vol + CM delaylaXL + Strymon El Cap in
the loop, with stereo return from the el cap) the popping and aliasing when
switching rigs is almost non existing.

What´s
more, If I use the stereo loop and I time a volume-knob decrease to zero with
the first delay repeat from any of the two delays I get a pretty loud aliasing
(louder than the dry signal) just before the sound crackles to death in the
decay.

If suspect the
loop configuration has been the biggest contribution to the popping.

This
problem does not occur when the loop is mute/disengaged and I use the onboard
delay!

That might be the problem.

Kemper Profiler Operating System 2.0.1 Release
- fixed: avoiding ‘Clicks’ that had been experienced by some users

Argh –
stupid me.

Bear with me, I just got a new job, house and a wife (Well – the
wife is not “new”, but the “wife” bit is)

That one
was running right by my nose…

Thanks for pointing out the obvious!

ok – now with
firmware update.

I did this
little recording – it´s a RC-3 mono into my “loop” chain while I chance rigs. The
delay is a long delay form the El-Cap (the same thing happens with the
DelaylaXL)

Don´t mind
the volume difference, but listen to this:

A points
just before the rig chances, you get a sudden but short volume increase – it´s
not really a pop to me.

AND

Listen
especially to the part from 0.52 - 1.02 – This is my MAIN problem. Even though I
DON´T chance rigs there, I get at some point a sudden volume increase in the
delay decay!

THIS DOES
NOT HAPPEN WHEN I DISENGAGE THE LOOP AND RUN ONBOARD DELAY.
THIS DOES NOT HAPPEN WHEN I ENGAGE THE LOOP BUT DISENGAGE EVERYTHING IN IT.

Same thing
on headphones.

I use the
stereo loop and run the main out to two studio monitors. Doesn’t matter if
there is something in front of the Kemper.

I have send a support ticket

hm - just to close this topic for me:

I have to send my KPA for repair - looks like the return has a hardware failure and my wierd problems come from there

Any news on this case? I have clicks when switching rigs in browser mode and performance mode.

This happens with/without a midi pedal. The plan was to use the Kemper live, but now I'm not so sure that's possible.

Sorry, that I chime in late:
When the rig change crackles with an active effects loop, it helps to set Direct Output Source to 'Git+Processing'.

Background: the default setting for the direct out is 'Git Analog", to provide a direct analog buffer amp, e.g. for reamping.
Whenever the effects loop is activated, the direct output is switched to the DSP path by obvious reasons. This cannot happen with the same accuracy and timing as the rig change itself, thus producing an artifact.

Setting Direct Output Source to 'Git+Processing' prevents the need for this internal switching.

That didn't do anything for me. I still have click/small crackle with no fx loop activated when switching rigs.

I have the same problem when switching between banks in performance mode. It's not subtle either. It's a very loud crackle.

I know CK is on the case of fixing this and has acknowledged this problem. When this problem first came about CK did mention in a thread that he was in the process of sorting it. I'm sure this will be sorted soon

I hope so
