If it can't do this, why did I buy it?
I can either create a mixdown and see if that will let me do fade-in/out at beginning and end of song....or try exporting the parts and using Cubase to do it...or create the final song and use WaveLab to finish up.
I'm still waiting on the ridiculously long downloads in Samplitude Music Studio 2013 to finish so I can try using that.
