With master and channel feeders unchanged, the volume goes down while changing songs from my MacBook Pro + Djay Pro AI
What do you mean by “changing songs”? What exactly are you doing?
- You may get level/volume changes if the autogain is ON.
By “changing song” I mean when mixing from one song into another song my volume is not consistent.
I’d try turning a few things on/off and see if it makes a difference.
- Auto Gain [Preferences > Mixer]
- Reset (EQ, fx, controls) [Preferences > General]
also check your Crossfader Curve under Mixer and Sync Mode settings under General.
