ReWire Tutorial Article Cubase 4 - Step 5: Rendering Audio
Most often, there is no need to convert individual ReWire channels to regular audio tracks. The channels already appear in Cubase’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 Cubase only, or simply to mix down all tracks including any ReWire channels to a single file. To render ReWire channels to audio tracks in Cubase, 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 Cubase. 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. Go to Cubase's Project window and set the left and right locator to encompass the whole song (or a section, if that's what you want).
Make sure the Cycle (loop) function is turned off.
4. From the File menu, select Export -> Audio Mixdown. You will be presented with a number of options.
5. Activate the "Import to Pool" and "Import to Track" options and fill in the rest of the dialog as desired. You can select file format, file name, as well as bit depth and sample rate, etc.
6. Press the Export button (see image).
The ReWire channel is now rendered to a new audio file on disk. A clip referring to the file will appear in the Pool, and an audio event playing this clip will be created and placed on a new audio track, starting at the left locator.
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.
To convert all your ReWire channels this way, simply proceed as above, but solo other ReWire channels in the Cubase’s Mixer.
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!
