I can reproduce this problem every single time; take a random rig and transpose it up or down using the ‘Transpose’ function in the Input section in Rig Manager (PC Version). It works fine, but when I tranpose it back to the origibal setting, the Kemper will overdrive like crazy and produce a lot of unwanted noise. So fa it seems the only way to solve this is by turning the unit off and on again.
Is this a known issue? Is it mine? Why is this even happening?
