Direct Profile = full amp without cab/mic
As i understand it, Bigtoe intended to make a preamp profile and called it direct profile, because that is the name that was used for that kind of profiles ever since the beginning on rig exchange. Profiles from the speaker out are called direct amp profile.
Direct Profile = Preamp profile. Some people use them with their guitar power amps. They exist next to full amp profiles. Taken from loop send/after preamp. The question if they should occupy just the amp section or the whole profile is something Kemper hasn't worked on yet, obviously, and therefore the process that tells cab and amp apart can't detect a preamp signal correctly. That's why the auto detect didn't work with Bigtoes profile and the cab section got occupied.
Direct Amp Profile = What Deadlightstudio spoke of: Profile from the speaker out that contains the full amp signal. Can be detected by the Kemper and automatically gets reduced to the amp section. At least that's how it should be.
