I'll attach here our signal map and the monitored midi commands of one of the performances that has the problem.

Hi guys!

I'm working as a guitar tech with a band that uses Kempers and MIDI automation at live shows. All the players have their own unit + spare. The problem appears with every unit.

We have this exact same problem. It's happening with multiple performances randomly. High Gain sound is suddenly clean, wet lead is dry, AC sim is distorted. Even The Kemper front panel and remote is showing the correct slot and sound + effects, the audio is wrong.

We use PC to call the performance, but after this problem appeared, we have tired also CC #47 #50-54 with no difference.

When the issue is on, manually moving to next slot and back to the original, the sound is correct again.

This is a massive problem since we have a stadium concert coming in a month!

Hope someone will figure out what's the reason. Thank you for your help and it's very comforting to hear that others also have faced the same issues.

Hi!

Did you find solution for this problem?

We are having major Kemper/MIDI issues. Would be nice to know if somebody else has this.

Performances load correctly with footswitch and front panel, but do not work with MIDI.

The problem has been the same from the beginning, and it repeats randomly. In the first place, we used only PC commands for building the MIDI files (MSB/ LSB #32 + PC). When the problem appeared again, and loading backup or rebuilding the performance didn't solve the problem anymore, we used CC #47 command for calling the right performance and after that #50 - #54 to select the first slot. After that command the file is the same as before.
Well, this helped for a moment, maybe 5 gigs, until it started again. There were no changes with the files nor the performances. It seems to be repeating every time when we go through the complete setlist. In the soundcheck when we are testing the sounds, it'll appear approximately every fifth time. The first sound of the performance looks right in the front panel, but is not right in the ears. High Gain sound is suddenly clean, Wet delay sound is suddenly dry with no effects, Intro riff sound is suddenly mute. When we manually go to another slot and back to the first one, the sound is right. This is serious problem.

We are having this issue with multiple performances, four different Kemper units and different MIDI devices.

Ticket opened a year ago, Kemper support offers "corrupted" performances or files. Tried to load backup, tried to save the performance to another location and save it again to the right place using the destination parameter, no help.

We have a Stadium show coming in June so really need to get this fixed, I hope somebody wiser can help! Thank you so much!
