If I understand correctly, when I add a cabinet to a DI profile, that profile becomes a Merged profile as the only difference between the two is the presence of the cabinet in the rig. That being the case, when profiling an amp and cabinet, I would have thought that the studio profile need only be taken once with an optimal mic position (more for different micing options obviously). Once a merged profile has been created from that Studio profile and its corresponding DI profile, subsequent merged profiles can be created using the resulting cabinet and differing DI profiles of the same amp without having to take further studio profiles.
Does the above sound reasonable?
My thinking is that I can optimise my micing and the Kemper profiling EQ prior to taking the single Studio profile so that I get the best possible profile of the cabinet+ microphone and then flatten the Profiler EQ for taking the DI profiles so that I effectively 'fix' any frequencies that I don't like from my awful micing technique but maintain the EQ settings of the amp itself (within the DI profiles).
