: CLA Vocals is an "all-in-one" processor that runs compression, EQ, reverb, delay, and pitch effects simultaneously. This heavy processing can cause your DAW to stutter if your buffer size is set too low. Increasing your buffer to 128 or 256 samples can often resolve this.

If the plugin isn't loading or causes your DAW to crash, follow these verified troubleshooting steps from the Waves Support documentation: Troubleshooting Audio Artifacts in SuperRack Performer
