OTT is a free dynamic range compressor plugin from Xfer Records, available in VST, AU, and AAX formats for use in digital audio workstations like Avid Pro Tools, Logic Pro, Ableton Live, and others. It uses three-band multiband compression to control dynamics across frequency ranges and is widely used by music producers, sound designers, and mixing engineers for both creative and corrective compression tasks. A native Apple Silicon (Universal) build has been confirmed running on Macs in the Rosetta Check community.
AI Recommendation
1 suggestionOTT ships with native Apple Silicon support in its current builds. For the AAX version in Pro Tools, you need Pro Tools itself to be running a native Apple Silicon build (Pro Tools 2023.6 or later) — the plugin will then load natively. If you are still running Pro Tools under Rosetta, update Pro Tools first via Avid's Application Manager to the latest native version; once Pro Tools is native, re-download and install the latest OTT from xferrecords.com/freeware and the AAX plugin will load natively. If you have an older OTT version installed, the installer will replace it automatically — no manual uninstall is required. You can verify the native build is running by checking the plugin's architecture in Pro Tools or using Activity Monitor to confirm the process shows "Apple Silicon" architecture rather than "Intel".
