Reamped sound wildy different

Hey Mike, did I get it right you're using the front input for the purpose?

This is a guitar input. Please read the manual, you have to use a line-level input (the Return, in this specific case).

Sorry If I misunderstood you

Did you use SPDIF?

In that case - make sure that your interface's clock is set to 44.1 kHz. Also, there are some clicks, sounds like the clock source was set to your internal sound card instead of having the Kemper as a master.

mother stupid question: You're sure you sent the right (raw) track to be reamped, not the already processed one, right?

Sounds too me like the DI is not hot enough. From the guide I put together.

Adjust the DI output level: This is the commonly ignored step that leads people to get into trouble when their DI recording is not hot enough/too hot for the reamping process, which causes trouble down the line. Click on the input menu and adjust the clean sense parameter to a level where clean sounds have the same loudness as the distorted sounds. Using Git/Stack in the output section would be useful in such a situation, as would having more inputs on your interface. This basically ensures that the git studio output is perfectly leveled while keeping the noise floor down - adjusting the dynamics of the instrument to the digital headroom of the profiler. The input LED is a helpful indicator in this regard: it should flash yellow consistently when hitting the strings hard. However, avoid a deep orange or red colour, which could result in clipping in the DI signal.

Then when reamping: You need to play back the DI track through your Kemper and watch the input LED. It should turn to yellow on the hardest string hits, but not more. You need to set the appropriate level for the DI signal from within your DAW by raising or lowering the volume on the DI track. Note, this cannot be set in the Kemper.

Try this and let us know.

PS: Whaddya know? I made 'Master'

Wow, congratulations!
