Hey Divas:
Don't despair!! We'll get you sorted out, just hang tough.
Try this:
1. Open your midi file in sonar. When you play it do you hear it? If you do then do this:
2. Click on the number of each track you want to render while holding down the cntrl key on your keyboard. The track number is found on the left hand side of each track.
3. While still holding the cntrl key click on the software synthesizer that's feeding the tracks. It should have a name like "Kontakt" or "sampletank".
4. Right up above the tracks are a list of names: view/options/tracks. Click on "tracks" and you'll get a drop-down menu.
5. From the drop down menu click "bounce to tracks". A new screen will appear. Click "OK". Sonar will now render your midi files to a new track which will appear at the bottom of your project. It will be namesd something like "5 New track". That new track is a wav file that contains your audio data.
6. To the right of each track name are two letters, "m" and "s". Click the "s" on your new track. Click on the audio track too (it will look like a big squiggly line). It should turn light grey.
7. On the upper left of Sonar click on "file". A drop-down menu will appear. Go down to "export". Click it.
8. Click "audio". A new dialog box will appear.
9. At the very top of that box set the location you want your file to reside in (I usually create a folder on my desk top).
10. Then name your file (usually the song name).
11. Under "type of file" choose either MP3 (though you'll need to buy the encoder to use that option), or Wave.
12. Decide what sample rate and bit depth you want. Just to be safe use 41,000 for the sample rate and 16 for the bit depth.
13. Click "export"
14. Go look in your destination folder and you should see your song!!
I hope this helps. If not then let us know.
Good luck!
