I killed and then resurrected my Kemper - I'm curious as to how so I don't make the same mistake again!

Hello all,

I haven't raised a support ticket here because I got my unit working again - if you folks think I still should, I'll do so.

My problem? I've been on the Beta software 3.1.2. I hadn't bothered updating as I've had zero issues and I know that NAMM is promising great things so I just left it. However, last night, I got this:-

[Blocked Image: http://i1287.photobucket.com/albums/a634/Gary_W_/IMG_3150_zpsbbpw9flp.jpg]

Rebooting didn't fix it. Rebooting whilst holding the Rig button did not fix it. Rebooting whilst holding the system button didn't fix it. What did? I had to reboot whilst holding the top left key above the display and then did a complete reset, deleting everything. With a big sigh of relief, I can confirm I have a working unit again but it's made me nervous about what I was doing. What was I doing? Well.....

I've never really used performance mode - I've only played live a couple of times in the last 2 years since getting my Kemper and both times have been acoustic. I have a Profiler Remote but have only really used that at home to turn stomps on or off on a particular profile / play with the expression pedal. I decided last night that it was time to change this.

The performances I had in there were from Maurizo (one of his backups). He is, of course, a generous genius but I wanted my own. I did not want to delete individually on the Kemper - I thought I'd do it as a block in Rig Manager. I selected all the performances on the Kemper and, after backing them up to Rig Manager, I told it to delete them from my Kemper. It warned me it couldn't be undone and then I deleted them.

I then created my own performance in Rig Manager and started dragging profiles into it. I renamed them in Rig Manager. I only did this in performance slot one.

I selected performance mode on the Kemper and it still had Maurizo's old performance in there. Rig Manager disagreed - it said mine was there, all his were gone. I put the Kemper back into browser mode and tried to figure out what was going on. At that point, it went back to a screen that simply said 'Kemper Profiler' and had locked up. When I rebooted (I had no other choice) I had the error code I posted.

So here I am, fixed. I have just factory amps on there and will probably keep it that way until the new firmware is out (I'm in front of Rig Manager so it's no problem to use my favourites from here). I'm keen to start making my own performances from Rig Manager but I'm a little bit nervous.

Any thoughts gratefully received

Yup, you should contact support
(it's even indicated at the end of the error message )

Put the OS in the root folder of a USB and boot up while holding the both the page < > down this should sort it.

i wonder if you had a corrupt rig in performance mode.

if you have a backup I'd also send this to support for them to look at

DamianGreda · Jan 21st 2016

it seems you've corrupted KPA database somehow.
I think if you do some performances from scratch now everything should be ok(after this kpa factory reset).

Gary_W · Jan 21st 2016

Thanks for the replies, folks.

I contacted support this morning and they replied really quickly (inside 30 mins which I thought was great).

Basically saying 'probably nothing to worry about'. Issue could have been caused by beta firmware plus someone else's backup plus me playing with performance mode in Rig Manager whilst I was in Browse mode on the profiler.

I was going to wait for 4.0 (as we now know it is) but, as it's saying 'some time in Feb' I'll put the latest release software on the Profiler and start building some performances.

Thanks again

You should update to 3.2.1 in the meantime. The bug you've experienced is a known bug in that Beta.

Gary_W · Jan 22nd 2016

Thanks Timo,

I put 3.2.1 on there last night. I had little time to play afterwards but so far, so good. Over the weekend I'll try to build some performances using Rig Manager and see how it goes

Monkey_Man · Jan 22nd 2016

It might be a known bug in that beta, but I experienced this on my first day with the Kemper, and never since.

It arrived from the factory with FW v2.7.

Forced an OS update using the root level of the USB folder, which cured the "lockup".

viabcroce · Jan 23rd 2016

Anyway, generally speaking (and for Release versions of the OS) I'd advise to always send these messages along with a backup. This will help Kemper to better tune the software.

Monkey_Man · Jan 23rd 2016

Agreed Gianfranco.

I've a good excuse not to have done this 'though - I've never owned a camera (no portable "i" devices either).

That said, I still wrote the details of the screen down and mailed them to HJS, being the good bloke I am.

Good monkey_boy

[Monkey jumps up and down* on the spot...]

A banana, Gianfranco? A banana?

* Folks talk about jumping up and down on the spot, but it seems to me that one only need jump upwards.

viabcroce · Jan 24th 2016

Now this was profound.

Actually, either you jump on, or you go up and down I guess...

Wow !!! it's probably a Zombie Kemper now, I'd check a doctor here ( Ingolf ?) if you ever get bitten by the beast ...

viabcroce · Jan 25th 2016

... We might have it bite other amps then ...

An undead Kemper can get epidemic fast
Beware!
