rok,

Couple of questions need to be answered.

First are all of the "audio" parts of the song
in your Seq file.

If so you can Click Audio at top left.
Select Merge Audio and VSTi/DXi tracks to Stereo.
This will create a stereo wav file containing all parts of the
song.

I use Audacity with Lame mp3 encoder installed.
Load the wave file into Audacity.
Edit out the beginning space and end space.
Maybe edit in Fade-in and Also Fade-out.

Export from Audacity as Mp3.

Second,

If you have midi in your seq file and are using external midi keyboard or Ketron type device
you will need to play and record.

Keep in mind if midi is playing thru a VSTi the first paragraph takes care
of this.

Hope this helps a bit.
