204 Controlling playback
Track-by-track playback
Using mono VST plug-ins on stereo tracks may cause out of sync audio
When using a mono VST plug-in on a stereo track (interleave set to Stereo), the left and right
channels will be out of sync. The left channel is processed by the mono effect, and delay
compensation is applied, while the right channel is not processed and does not have delay
compensation applied. The signal will look something like this:
• Left channel: Wet signal (delayed)
• Right channel: Dry signal (no delay)
A mono VST plug-in will work correctly if Enable Mono Processing is checked in the VST Plug-in
Properties dialog box and the track interleave is set to mono.
See:
“Changing track settings” on page 205
Note: Enable Mono Processing is enabled by default in SONAR. If you are playing back a
legacy project in SONAR and notice the project does not sound the same, try to disable Enable
Mono Processing for any mono plug-ins used in the project.
