I don't use Producer X1 very often so need a little kick start pointing me in the right direction.  (I usually do my scoring in Sibelius 7 now).  I have a project completed that sounds great using a dozen or so tracks - all MIDI using GIG files and the GPlayer for my sampler VST.  I am on Windows 7 64.
 
How do I create a WAV file from this project?
