Stereo Level Indication

Since I didn’t built my MIDI Mon yet and I still have to learn a lot about the MIDI protocol, I hope somebody can answer following question:

What do most of the host applications send for level indication if it monitors a stereo fader?

  • is it a “mono” indication? Something like the two signals coupled minus 3 dB.

  • does it send a separate left and right level indication? If yes, what does it send in mono mode… two separate left and right levels of the same amount?
