ParallelAggressor

ParallelAggressor is an AAX plugin component of Avid Pro Tools, not a standalone application. To update it, you need to update Pro Tools itself through Avid's official update mechanism. First, ensure Pro Tools is running version 2023.6 or newer — this is the minimum version with native Apple Silicon support. Launch Pro Tools, go to Help → Check for Updates, and install the latest version available. Once Pro Tools is on a current native build, the plugin will be included. If you are still on an older Intel-only version of Pro Tools, updating to 2023.6 or later will give you both the native Pro Tools application and any bundled or marketplace plugins in their native forms. For third-party Babyaudio plugins obtained outside of Pro Tools' plugin marketplace, visit babyaudio.net or use their installer if you have one — but the primary path is ensuring Pro Tools itself is current.
