i believe its called Cubase, bro
Assuming that you've already recorded separate tracks in a new 'project' already...
You should be asking on how to "render" the track/s to a wave file..right?
Select the time frame on your single/multiple tracks together, then go to the file menu and search for 'render' (should be...as i remembered heh)
The resultant file will be a big ass 'song name.wav' file.
You can then use after-market mp3 encoding programs to convert the wave file to a compressed mp3 file.
Depending on which version of Cubase you have, it should be basically the same on the rendering functions.
If in doubt, always press F1, Ctrl-F and type 'Render'. :wink:
Hope this helps.
