If you're using the merging feature like this formulation suggests (and I might be wrong), you probably get sub-par results. The merge feature is not supposed to be used for merging just any cabinet with any direct profile, but only for merging a studio profile and a direct profile of the exact same physical rig (profiled in succession). The purpose is to improve the accuracy of the amp-part and the cabinet-part of the studio profile, the result is then called a merged profile. If the direct profile and the studio profile come from the exact same physical rig, it makes sense that the KPA could find some finer details in the direct profile which it then implements also in the studio profile etc. If the direct and studio profiles are from two different physical rigs, the merging process will still operate on the assumption that they are from the same physical rig, meaning that any changes by the merging process are likely to decrease the accuracy of the sound.
Luckily, making a profile from separate amp- and cab-parts is encouraged and is even easier: just replace the cabinet-part of the profile by another cabinet preset, or replace the amplifier-part by another amplifier preset (such as a direct profile). I guess you could experiment with unorthodox merging and hope that it accidentally produces something good-sounding, but it's not in the spirit of the product (accurately replicating sounds of real amps).
Hope that helps..
PS. I agree there are many high quality sounds in the Cililab Mk5:25 pack!
Thanks for the insight! I never considered it that the new Profiling algorythm increased the precision/authenticity of the Studio Profile by using the the Direct Amp Profile. So far I haven't ventured into profiling myself and I was under the assumption that the Studio Profiling and the Direct Profiling were twoseperate/ independant procedures...
If I follow this train of thought, the Direct Amp profile will not increase in quality only the Studio Profile will so maybe I should use the matching cabs provided in the derived Studio Profiles...
But those Ownhammer IR's, man, so good!
