Hi guys, so the first thing that I do, is open up a Demo Project "Mixing Tutorial Complete":
 

 
Then, i set Bass Guitar as solo,
 
 
 
I add Z3TA+2 soft synth,
 
 
And I copy and paste the Bass Guitar tune onto Z3TA + 2
 
 
But it doesn't play sound!? I tried different options in the Z3TA+2 dialog, and I tried opening up other projects and create a new project, it just doesn't seem to work with Music Creator 6 (I don't have other DAW):
 
 
 
I've frustrated over this for hours. Please help!! :(
 

I don't have Z3TA+2 or MC 6T, but I think that Z3TA, being a soft synth, needs MIDI data to play it, not audio data.
Or, if that is an Instrument Track (MIDI and audio in one track), you'll need to find the MIDI info in the track and set it's output to Z3Ta. Not sure how that's done, either.
Welcome to the forum.

Yeah, the track has an instrument track icon. MC6T will copy and paste audio into an instrument or MIDI track but ignores the data. The only valid input for instrument and MIDI tracks is MIDI. An instrument track will not play audio loops. Z3TA+2 is a synth, not an effect, so it needs MIDI to make a sound.
