ReWire Tutorial Article ProTools - Step 4: Rendering Audio

Most often, there is no need to convert individual ReWire channels to regular audio tracks. The channels already appear in ProTools’ 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 ProTools only, or simply to mix down all tracks including any ReWire channels to a single file. To render ReWire channels to audio tracks in ProTools, proceed as follows:

1. Make sure Reason plays back properly via ReWire.

2. Activate solo for the ReWire channels that you wish to bounce down (render) to an audio file. When you press play you should only hear the ReWire channels, including any effects or processing added in ProTools. 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 Pro Tools and select Bounce to -> Disk... to open the Bounce to Disk dialog where you can choose a file format, bit resolution, and whether to convert and/or import the bounced files after the operation. Click the Help button for more information about the Bounce to Disk dialog.

4. From the "Bounce Source" pop-up, select the output or bus path you wish to render to a file. To preserve the individual ReWire channels instead of mixing them down to a single file, there are two basic methods you can use: * Route each audio track/Reason channel to separate outputs, and perform a bounce for each separate output/bus path. * If you have routed all ReWire channels to the same output in Pro Tools, you have to solo individual channels and perform a bounce for each separate channel.

5. When things are set up the way you want them, click "Bounce".

6. A new dialog appears where you can type in a name and select a destination folder for the resulting files. Click Save to start the bounce operation.

The ReWire channel is now rendered to a new audio file on disk.

7. Before importing and playing back the new files, mute the original tracks playing the ReWire channels.

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!
