I do not notice most RTs being too loud, bu rather find myself needing to boost them to make them fit in the mix.
Is your MIDI source too soft?
I think some of each, MIDI too soft, RTs too loud. The melody track is showing velocity 90 on the piano roll and vol 90 on the mixer. I have both master volume faders at around half scale and with those settings I get whole-mix volume meter readings mostly entirely in the green. My synth here is VSTSynthFont64 ... I wonder if that's a factor.
When I switch to a RealTracks style, with the settings the same I get the master volume meters right up the top of red.
But I also had that issue where I balanced the MIDI mix and saved the MGU whilst the song was playing and the volumes immediately jumped up to similar to the RTs. I balanced it again, saved again and tyhey jumped up again. I did it a thord time. Now all my mixer settings are around 36...40, my master volumes are midway for "All Songs" and around 2/3 for "This Song" and the master meters are topping the red again. Another time and the levels stay as I would expect. I try to find if it'a relaated to saving whilst the song is playing, but it appears inconsistent.
There are jsut too many variables and too many oddities here to make any real sense of this at all.
Hmmm ... I haven't yet tried an RTFS and I haven't yet tried rebooting Windows. I guess I'll try those tomorrow and they try again to work out exactly what changes and, as far as I can why. Then again, I have some work I need to finish, so I may just walk away again, at least for a while.
