**CorOS Version:** 4.1.0

**Describe your issue:**  
When im using Factory presets of the Arquetype petrucci on QuadCortex, using any scene thats labeled as SOLO, makes a lot of noise, its almost impossible to bring down with Plugin Gate utility.

I expected to be as clean as Neural DSPs video.

Pulling the I/O Settings, Ground lift is where its supposed to be.

what am i doing wrong?
