There is a problem with the groupgain when you do as follow:
A CSP desig with PM and ESP
Do a group of outputblock in PM, and open up the groupfader for that group.
After that clear the group.
Do another group of gainblock in ESP ( the gain on the gainblock on 0db)
When you open up the groupgain is the fader on 12, but the display on 0db, the gainblock is still on 0db.
If you don´t open up the groupfader in the first time with PM, than there is no problem the second time in ESP.
Good catch, thanks - will get it logged
