Hello...lovin the Garageband interface. How do you increase the overall volume of the songs in Mastering. I can't seem to pump these up, so they sound like a typical CD. Is there a parameter I'm missing?

Try adding the AUPeak limiter on the Master Track (in Track Info at the right of the interface). 4-6 dB of gain should do it!

Thankyou! Sounding waaay betta!
