Kemper Amps Forum

Quoted from "uweoverdrive"

You can measure latency (although I don´t know how) but you can´t measure the feel as mentioned by Per and me !!!!!!

Can you and Per please post a clip of the tones/rigs/profiles where you're feeling latency.

Personally, I don't think there's some kind of "felt" latency as well.

What you guys are experiencing may be a specific "attack"-feel from the original amp itself. Some amp models (profiles) feel "spongier" or more elastic than others. Others feel stiffer. It's all pretty normal - like with real amps.

The guys who profiled their amps should know if there is some perceived change in sound or feel from the amp they profiled. If there was a noticable latency when comparing the original to the profile - I'm sure they would have said so.

??? you cannot "hear" latency in a clip unless you close mic the acoustic sound of the strings as well. Somebody correct me if I'm wrong...

not necessarily, unless they are monitoring with in-ear or headphones, 5ms is the latency you experience sitting a 1,7m from the speaker

If I read all the posts of this thread again I realize that not only Me and Per are feeling someting but also fretbored1 (who startet the thread) gbs and Dogman
made similar experiences altough they described it a little bit different.

The problem is that you can´t hear it but only feel it, so that posting sound files is useless. The best thing is a direct personal comparison side by side as I have done it and will do it again and again with always the same result.

I´ve postet at the fractal forum that the ultimate solution is a modeller/profiler whatever that has the feel of the Axe and the rest (sound, easy to use etc.) of the kemper.

Yes, I didn't question this. What do you mean with "not necessarily"? It can't be a specific amp attack?

A simple approach to measuring latency is the following:


- Use an analog device to split the signal of your guitar (or any other signal generator you might want to use). Currently I use a DI box for this.

- Output No.1 (the XLR out of my DI Box) goes straight into one input of my computers soundcard

- Output No.2 (the "thru" of my DI Box) goes into the input of the Kemper and the Kempers output then to a second input of my soundcard

- Now I play a short, percussive signal and record both soundcard inputs in my DAW

- By comparing where the signal starts on each track you can measure exactly how big the delay/latency is that the Kemper introduces in relation to the unprocessed signal


I tried it with firmware 1.0.0, 1.0.3. and 1.0.4, without noisgate, with everything bypassed as well as with the amp-stack activated.
The outcome was always the same: 5 ms

Of course there´s always the possiblity of an error/mistake on my part but I measured other digital devices in the past with the exact same method and on the same recording-setup and always got results that where well within the respective manurfacturers claims.

I mean that sitting in the room with the amp and swapping from profile to real amp, would not necessarily make a so short latency evident, is enough that the amp is over 1,7m far to give it a higher latency then the sound coming out from the monitors. From the comments here I understand that is a quite consistent feel, not linked to specific profiles.

I know you can't hear latency in a clip, that's not why I asked for a clip.
I want to hear what they're playing when they feel this latency.

Got it, Lance.
