Occasional red is OK. Occasional - meaning for "scarce" peaks only. This has been confirmed by Kemper here on the forum. Note that the manual said, "... try to avoid..." when it spoke of going into the red. It didn't say your tone will instantly go to shite, because it won't... unless your signal actually lives there as opposed to poking its head in the door once in a while. The internal headroom on the unit is huge, BTW, in case you were wondering.

If you're reamping and still worried about it, turn the feed from your DAW down a couple 'o dB. If you're playing, back the bass' volume knob off 10%.

Yes, i was indeed wondering !
I see perfectly what you mean, thanks for this detailed answer. I was indeed trying to avoid orange and red blinking at all costs, in the DAW world it is -usualy- bad and a clipping indicator.

I guess that some bass players use a compressor before an amp in a normal playing situation, so use your ears and see if it sounds good really. I sometimes use automation to boost single note sections on a DI track before a guitar re-amp, but have not resorted to a limiter before.

Yes, automation is a good idea.

This is true for the OUTPUT LED section in the manual.

Here is what the INPUT section says : " The INPUT LED provides a further gauge for correct leveling: the LED should flash yellow when you hit the strings hard - try to avoid deep orange or red color. "

Despite clipping problems, too much input volume while reamping seems to have the same effect as turning the gain button up.

Thanks for your answer !
Although i agree with you, the goal is to cut some loud "peaks" not kill dynamics.
Without those peaks, the input light blinks green all the time, i just want to avoid lowering volume and loose gain in the end.
I've put Fabfilter proL2 which is famous for its transparency and did some testings, seems working well so far.
There are lots of cases (if not most of them) where you put a compressor/limiter between the Bass and the amp, somehow this is the same thing here.

What do you guys think ? I'd realy like to have some feedback and read about your experiments.

Hello all,

I have made several D.I tracks (Spdif Git/Stack setting) while first recording my bass.
Now i'd like to reamp those D.I tracks but i have a lots of volume variation, the input light blinks yellow and even red from time to time.
If i lower the volume i loose gain, so i'd like to know if i can compress or limit (without killing dynamics) the D.I track before sending it to the Kemper.
(Modern Alt Metal music, precision bass, Ampeg SVT Profile.)
I'd realy like to have some advices on the method and plugins to use, to ensure having a smooth reamping experience and results.

Thanks in advance for you help !

For the record, i've found out what was the problem : " remove dc offset during record " was checked.
Now it's unchecked and it works flawlessly.

Hello all !

I am actualy experiencing quite a nasty problem while trying to record my Kemper on my D.A.W using any " Git / xxx " mode.
ANY of these modes (from " Git / Stack " to " Git / Master Left ") generate audio artefacts / noise to all recorded audio each time i try to record BOTH sides (D.I and Processed) at the same time.
These audio artefacts and noises don't appear if i record only the processed side (left SPDIF coax) of the signal while in " Git / xxx " mode.

I am actualy recording takes for an album and getting both sides of the signal is mandatory for later reamping purposes.
This is realy stressing me out as i am slowly running out of time.
Sorry for my english and thanks in advance for your help.

My Kemper (OS " 5.5.0.13341b ") is hooked to my Fireface UC (latest drivers) in SPDIF mode and i use the latest Sonar Platinum " 23.10.0 Build 14 ".

Here is the recorded sound using the regular " Stack " mode (no noise) : http://mp3.jwar.fr/test-stack-processed.mp3
The recorded sound of the "Processed Side" while recording both sides at the same time : http://mp3.jwar.fr/test-gitstack-processed.mp3
The recorded sound of the "Unprocessed D.I side" while recording both sides at the same time : http://mp3.jwar.fr/test-gitstack-unprocessed.mp3
Here is my Fireface settings : [Blocked Image: http://mp3.jwar.fr/fireface.jpg]

Got it ! Thanks very much for your time and answer !

Hello all,

I was wondering : With the kemper, is it possible to output at the same time the current selcted profile sound AND a second totaly unprocessed signal for later reamp needs for example ?

If yes, could you explain me how ?

Thanks in advance for your help !

I realize my previous post wasn't clear at all

In fact, the constant latency helped reducing the phasing problem.
We didn't perceive any noticeable latency while playing the guitare while constant latency was enabled !

Sorry for the confusion and many thanks to everyone for the valuable help.

We gave it a try yesterday and we weren't able to perceive any difference when playing with or without constant latency.

Well, I can't be certain nighlight's suggestion is related to the issue, but constant latency chooses the latency of the rig gifted with... the highest latency, not some very high latency out of the blue.
IOW, if you are comfortable with laying that certain rig, you will experience no issues.
This rig might as well not be in your collection, it's probably defined as a rig where all the highest-latency fx and all the filters are used, or something along this line.

Personally, I've never perceived latency, not even with the CLR. But a friend of mine who tried my Profiler clearly felt a difference when switching from his combo to a CLR.
So it's also a matter of specific sensitivity I'd say.

Quote from http://www.wikpa.org/Latency :

" Although the default latency is variable, you can expect it to be
around 3ms.
Kemper decided to provide a hidden setting starting with firmware 1.6.0 public
beta to make the latency a little higher but constant. This constant
latency would be 4.9ms. "

wouldn't happen to have any buttons enabled by any chnace? look for X / MD / Delay / Reverb and disable.

Nope, everything's disabled

Are you sure ? They say " constant latency " is only to be used for REAMPING, as it sets the latency to the highest (slowest) value. Thus not being suitable for " live " recordings.

But i assume you tested it and it works just well for live recording as well ?

Thanks for the tips.

Here are the links (9mb each) :

the two takes set to 50%L 50%R : http://mp3.jwar.fr/test150L50R.wav
the two takes set to center : http://mp3.jwar.fr/test2center.wav

How do i know if there's any " post stack " processing ? (You mean reverb / delay etc ?)

I will upload a sample in few minutes.

Indeed i am using 44.1 and sync is set to external spdif.
No reamp used
Kemper Noise gate = 5

So in your opinion, no problems with panning multiple stereo takes ?

Hello there,

I am getting a quite annoying and unwanted " phaser " or " flanger " effect when playing two takes i just recorded.
Each take is using a simple Peavey 5150 patch whith " crunch " type disto (no efx / reverb / delay) and each take has been panned 50%L and 50R.

As recording through SPDIF gives me a stereo wave for each take, i was wondering if it could be the cause ?
For example, In my mix at the same time i have the rythm guitars 100% L/R and lead guitars 50 % L/R. Could it be a problem to record in stereo 2 takes of a same riff or lead and pan these 2 stereo takes ?
Actualy, if iam not mistaken even if each take comes in stereo signal, both sides of the wave are identical.

Help needed please.
Thanks in advance.

Ok guys, thanks again for all the advices

I understand, thank you very much for the info and links !

Anyway i still have a question, sorry to bother you, but if i lower all volumes so peaks are around -10db... My master will need even biggert amount of mix limiting to hit the actual loudness war standards. You see what i mean ?

Thanks all for your help. I am not sure to understand correctly what you're all saying tho ! so please correct me if i'm wrong :

- My daw being full 24bit processing, It's better to record my kemper at -8db than to try to be as close as possible to 0db ?
- In this case, how to compensate for the lost volume on the track where the kemper was recorded ? By raising the track gain or maybe track volume is better ?
- Is it the same thing for let's say... Virtual instruments, like easy drummer ? We should lower the volume on those tracks too ? I don't clearly get the point.

J.

I understand, thanks for your advice !
