DSP-Problem after FW-Update to 4.0.4 PB

  • 4.04 works fine for me and it fixed my morph to wah problem. It took a while to install but no problems.

    A brace of Suhrs, a Charvel, a toaster, an Apollo twin, a Mac, and a DXR10

  • Update:


    After fiddling with Monitor Output and setting it to Mod Mono, the sound gets muted and after some time Kemper being idle, the DSP error message has shown up:

    Then no signal from guitar is detected, tuner is stuck at "-26"

    After some time it asked "Recover?" I clicked Yes. Then I switched to Master Mono and rebooted and all was fine again.


    I have created backup and sent to motherland for analysis.

  • Hey,


    Had the same problem, came here for help. None of the solutions worked for me but that was because it wasn't a firmware problem. The DSP board inside had popped out.
    This video helped me find the solution:

    I was already about to send it to repair as the the support diagnosed it as a hardware problem but was very reliefed when the solution was this simple in the end. A chunk of money saved (warranty was out...)

  • I got that error message updating to the New beta firmware today; had to go back to previous firmware

  • @alexdoyleguitar and @oozish


    Which error message did you exactly receive? Did it say "DSP Error! Communication with DSP Board has failed." or something else?


    Please open a support ticket and send a backup plus instructions how to reproduce the issue.
