In which case should I use USB to Main (dB) and how

15.5.4 USB TO MAIN [dB]
Sets the amount of amplification of the sound that is streamed over USB to the Digitakt main out when used with Overbridge or as a class compliant audio device. (0 dB–+18 dB).

In which case should I use USB to Main (dB) when working with Overbridge and how?

I used it a few weeks ago when connecting my Digitakt to an iPhone for external processing. Set INT TO MAIN >>> Off so I could hear only the processed audio, and USB to MAIN +12. Because the signal was low of course.

That’s what I did but nothing happens. Maybe I need to understand where the signal starts and where does it end. I’m in the process of understanding all the little details from the manual.

There is a good description here:

Digitakt OS 1.11 beta - questions, issues, bugs, etc

USB to main is a boost-by-dB function for the oncoming audio signal via USB (from the computer to the Digitakt). I think it can be used be for leveling DAW master volume with Digitakt master volume when you are using both side-by-side, or lowering sample volume when sampling USB etc. On the other hand, Int to main allows you to turn off the Digitakt local audio if you’re routing/monitoring the Digitakt trough your DAW. That way you don’t get duplicate signal (DAW Digitakt + Local Digitakt) at t…

Are you sending audio over USB from another device to the Digitakt?
