Vocoder Sidechain Does Not Work Unless Low Latency Monitoring is Disabled
If you are working with a Vocoder, and you are using sidechain, you must disable Low Latency Monitoring. Low Latency Monitoring can be disabled under Studio One>Options (Preferences on Mac)>Audio Setup>Processing. It can also be disabled by clicking the icon of the green Z at the bottom of the fader in the Console or under "Instruments" in the Console.
