Reply To: UltraChannel AU Plugin not working in Garageband

Try downloading this version and see if it solves the issue. 3.4.0 wouldn't load in GarageBand, it was fixed in 3.5.0. The current version (3.7.3) should probably be fine on Big Sur: https://www.eventideaudio.com/support/downloads/quadravox-installer-mac-64-bit
