Yes, I can reproduce this issue. We'll fix this in a future firmware.
So far we have not been able to replicate this issue and the information, how this hang can be overcome, isn't consistent. In order to narrow in on the root cause, it would be extremely helpful to understand:
- When the unit seemed to hang, how long did you wait?
- Does booting the firmware from USB-stick always fix the issue at least for the moment?
- Does no reset (SYSTEM = Global Settings, RIG = Rig Buffer, QUICK = Midi Program Change assignments) fix the issue at least for the moment?
- Is it possible to overcome the hang by just trying and restarting a few times without any reset or booting from USB-stick.
we seem to have introduced this issue with firmware 1.5.1.
The two knobs Delay Feedback and Delay Mix are working as long as you stay on the main screen. If you open Delay editing these two know are disfunctional, but you can use the two softknobs for Mix and Feedback below the display instead. Please use this as a workaround for the time being.
Midi Control Change # 68 and 69 are working as well.
We'll fix this in our next firmware.

I have my room set up so ecverything comes on from a single switch with a delay between 3 sections, usually I just turn it off when I am done and don't really think about it.
When I turn the KPA off, there is a bit of a delay while it tells you it is turning off. Is it actually doing any important stuff then?
It might be a bit tough to remember I have to turn it off first!
If so, I'll put it on a different circuit, so it will be left on rather than be improperly
turned off accidentally.
The Profiler does have a protection switch protecting the unit from overcurrent. This switch could get activated, if you don't properly use the chickenhead to switch off and the protection will not release before the power supply will be completely empty. You might not notice, if you shut down for more than five minutes.
Checked the reference manual.
#34 Delay Mix
#35 Delay Feedback
#36 Reverb Mix
#37 Reverb Time
The change log however says:
#68 Delay Mix
#69 Delay Feedback
#70 Reverb Mix
#71 Reverb Time
So mic is right, this seems to be a mistake in either the manual or the change log!
The Change Log is the latest and greatest. The manual will be corrected soon.
Thanks for claryfiyng, Timo. It would be a good idea to put this tip in to FAQ/Wiki since is going to come more often...
There has been a FAQ related to this subject since quite a while. I guess, it's number 10 on the list.
I'm not sure if it is a direct connection between the shear count of Rigs and those problems, since I was over 2.000 and got the update to work with 1.672 rigs and Hoth was already in trouble with 1.500 and needed to cut down from there to make it work.
In a first attempt I deleted around 10 profiles from the backup to make it come out at 1.999 as I thought that maybe 2.000 was a magical number. Well it wasn't, it still wouldn't work. So I deleted much more rigs.
When I already had 1.1.1 reinstalled and the KPA up and running I tried a restore of that 2.000 rigs backup file and that would gave me the very same error message. Although the KPA would at least reboot with 1.1.1
The crash comes when the Kemper is about to reorganize his memory and it could be another issue as well. Maybe me and the other guys with problems all have the very same corrupted rig, who knows? I do know that I have every rig I could get hold on from very early on so it is impossible for me to try and see if a single profile is giving me this problem.
The error message is indicating a memory problem, which will depend on the number of rigs as well as presets (e. g. cabinet presets). Two customers have raised related support tickets, but we are still waiting for a backup in order to exactly reproduce the problem.
In any case it's a great idea to clean up and keep the number of rigs, which are stored on the Profiler, at a level, which is managable.
also had the error message when trying to update to 1.5
I´ve re-installed 1.1.1 (thanks to Armin´s recovery hints), cleaned every rig etc. with a "clean backup" and tried to update to 1.5 again: everything ok, update worked fine
Finally I checked my backup which I had taken prior to my update trials: man, I couldn´t believe I had 1894 rigs stored
Maybe a rig counter would make sense...?!
So I guess the problem with the update to 1.5 occurs if you have too many rigs stored (at least more than 1202 like Armin).
However, this was a good time to clean up my rigs
Best wishes to all of you,
.... regarding rig counter. In the Rig Browse screen you can see which position the rig actually selected has compared to the overall number of rigs matching the active filter e. g. 'Favourites'. If you select the filter 'All Rigs' you can see the amount of all your rigs there. In case you have just the factory rigs installed, this amount is actually 314.
We are happy and proudly announce, that our Kemper Profiling Amplifier as well as Access Virus TI have been nominated in the categories Effects and Processing Hardware and Keyboard/Synth by Sound On Sound.
Voting will close on Nov. 30th 2012. We highly appreciate your support!
Triggered by a customer request we learned today, that you could use a normal volume pedal e. g. Ernie Ball instead of an expression pedal. You just need a standard Insert cable (TRS jack on one side and two TS jacks on the other ends). Plug the TS jacks into in- and outputs of your pedal and the TRS jack into the Profiler. Now you could even use your Ernie Ball pedal to control your Wah. Sorry, if that's no news for you!
We have not been able to reproduce any malfunctions caused by rigs nor presets in any recent firmware.
The Kemper Profiling Amplifier features more than 400 different MIDI parameters. Normally MIDI Controllers can only handle up to 128 parameters max. This is why we are supporting the extended Midi Controller format NRPN (Non Registered Parameter Numbers).
Please find a documentation of these parameters on our download page for your convenience:
Please choose category Documents and download our Profiler MIDI Parameter Guide.
i'm about to buy an UPS for my KPA, but the problem is i cannot find any information about how many watts and amps does the KPA need to work..
helps please ..
The technical specs say
Is there an easy way to move profiles inside the Kemper? Iam using just an up-down footswitch and want certain profiles next to each other in browse mode
Are you aware, that since firmware 1.1.1 Public Beta you can filter rigs by Current Author, Favourites, Last Imported, My Rigs as well as sort by Name, Author, Date, Amp, Gain?
If you for example flag 20 rigs as 'Favourite', select this filter and sort them by Gain, your up/down switch will scroll through those 20 rigs in gain order.
This opens lots of opportunities to organize your rigs.
what is the impedance of the headphones on the kemper
a Beyer DT 770 PRO impedance 250 ohms
it's ok for the kemper
Specifications: Dedicated Headphone Output: ¼ inch TRS stereo, 33Ohm
I'm using exactly this headphone (the 250 ohms version) for test purposes and can recommend it.
Reported at least by another user...if you have too please report
Hello, we have not been able to reproduce any of this. May I ask you to please open a support case and ideally send us a small recording of the noise, so that we are getting an idea.
I'm not sure if this is related to my "select a snapshot-> rig that the snapshot belongs to doesn't get selected"-problem.
But I had encountered what I suspect to be a bug (or a feature of questionable usefulness). I tried to save 3 rigs that I have also stored as snapshots in some midi slots.
The rigs didn't even show up in the rig-list (yes I didn't filter any), so I had to save (Rename -> Store button without changing name) them again to have them selected.
I put my rig "EVH5150" in slot 10, then "Crunch 2" in slot 7, then "Clean 2" in slot 6. When I scrolled up to slot 10 to see if everything was right, "Clean 2" was in slot 6, 7 and 10!
I encountered that problem a few times before, but couldn't really remember what exact steps I took...
Not sure if this warrants an extra thread, if so then I'm sorry
Edit: I think this warrants an extra thread... The problem with my rig-midi slot settings getting overwritten seems to be related with my rigs that I saved as snapshots not displaying in the rig list. If I save the rig that I just selected from the snapshot list, it gets displayed in the rig list. If I do the same with another rig, the first one seems to get removed. While trying to confirm this hypothesis just now, my KPA overwrote another midi slot that I saved a few minutes ago and that I didn't select in the midi program settings before (I'm pretty sure of that, at least)
I don't really get it, but I hope this report helps. Sorry that I'm posting this in the feature request forum, I'll copypaste this in the troubleshooting forum as well. It seemed related to the original problem
I understand, what you are really looking for is an efective way to reduce the list of rigs to scroll through. With firmware 1.1.1 Public Beta we have introduced new filters like for example My Rigs or Last Imported. The new filter Favourites is exactly for the purpose to create a reduced list of preferred rigs. Please apply this new feature. These are normal rigs with the usual Midi Program Change # assignment handling. Snapshots - as the name indicates - have been designed for a different purpose.
Please make sure, that you create a tar archive at the end of the clean up work as documented! Any compressed archive formats like for example 7z archives don't get accepted by the Profiler.
While I was trying some of my rigs today with the new update I heard that the lead booster was sounding weird..like it didn't feed the amp but was set parallel to the amp
I tried to revert to 1.1.0 but got a software error at reboot..after 3 tries I had to do a system reset to be able to reboot... My rigs sound fine with 1.1.0
Just reinstalled 1.1.1 and it still the same weird thing
Here is the rig if you want to try
and here is the error pic for support

May I ask you to open a support ticket on our web page under support/e-mail us. We'll respond to you and ask for a complete backup of your Profiler to investigate the issue.
