Master volume issue when dialing Master Volume knob repeatedly

I have a Kemper PowerHead with FW 3.1.4.

I've noticed a very strange behavior regarding the master volume.

If you turn the master volume from 0 to something like 3 and back to 0 repeatedly times, you will notice a volume drop each time you do that. You can hear that the sound will remain cut off until later in the volume number. For example, for the first time the volume at 0.1 will already have some sound, next time only at 0.3, then 0.7, then 1.0, and so on.

I had to turn off and on my kemper to restore the normal behavior in volume.

I was using the internal power amp. Don't know if it will happen to the studio main outputs.

Same issue here.

Go into the output settings page 2/7. Now turn the master volume up and down repeatedly. The monitor volume and headphone volume will reach a lower maximum value every time and will eventually stay at zero (when linked to master vol)
The direct volume and main volume are unaffected when linked.

Can someone confirm, or is this a known issue?

Yes!!!! That´s exactly the cause of the problem I was hearing in the monitor output (wrong calculation of the linked volumes).

I did the same test you describe and got the same issue here.

And the same in 3.2.0 .

Support mail has been submitted. Thanks for checking.

I encountered this too and contacted support. They offered a solution, whilst not fixing the issue it explained a reason for the "weirdness" you have described. See here:
SOLVED: output recall not fully recalling and volume link broken

Slateboy,

That is certainly related, but the result is different here.
If you link the monitor volume to the master volume knob, the maximum value of the monitor volume will decrease (eventually at zero) when using the master volume knob.
