Following FW version 5.7.x this fix has been introduced:
QuotePROFILER Operating System 5.7.0.14092
Audio
fixed: parts of amp sound accidentally bleeding into cabinet sound while AMP module is switched off and CAB module is switched on
Quite often, I use the KPA for just the cabinet block only with an external preamp, re-amping etc. (mainly recording purposes where i have a post-amp/pre-cab signal)
The cabinets now all sound noticeably different. They have much less bass, less highs and more mid, to my ears.
Perhaps they are now correct but having been using this arrangement for the past few years they are no longer useable having based everything on how they were.
Any solutions or workarounds to get back the "old" cab sounds? (other than applying corrective EQ)
Perhaps a more in-depth explanation of the fix applied would assist finding a way round this?
PS: Rigs with the full profile chain (amp+cab=stack) still appear to sound the same, so as a stand-alone, the KPA appears unaffected.
