ReWire Tutorial Article Sonar - Step 4: Rendering Audio
Most often, there is no need to convert individual ReWire channels to regular audio tracks. The channels already appear in Sonar’s mixer, and you can typically perform the same kind of real-time processing as with regular audio channels (effects, EQ, volume, pan and mute automation, etc.).
Still, you may need to convert the ReWire channels to audio tracks, for example if you want to continue working in Sonar only, or simply to mix down all tracks including any ReWire channels to a single file. To render ReWire channels to audio tracks in Sonar, proceed as follows:
1. Make sure Reason plays back properly via ReWire.
2. Activate solo for the ReWire channels that you wish to export (render) to an audio file. When you press play you should only hear the ReWire channels, including any effects or processing added in Sonar. What you hear is exactly what you will get in the resulting file. If you wish to preserve the individual ReWire channels instead of mixing them down, you should perform a bounce separately for each individual ReWire channel.
3. Pull down the File menu in Sonar and select Export -> Audio... to open the Audio Export dialog, where you can choose a file format and bit resolution, etc. When you’re satisfied with the settings, press the Export button.
Sonar will now playback your arrangement and render the soloed tracks to audio files.
When Sonar has finished bouncing the tracks, import them into your arrangement.
If you now play back the audio track you will hear exactly what was played on the ReWire channel. This means you should keep the ReWire channels muted (or deactivated) now, since otherwise you would hear the sound twice - once via ReWire and once from the audio track.
Note: Converting ReWire channels this way results in a number of large audio files (depending on the length of the song). Make sure you have enough disk space!
