EastWest frequently releases official "fixed" versions to resolve specific engine bugs. According to official update logs, recent fixes include:
: A known quirk when moving from Play to Opus is that you must manually select "Install Product" within the settings for each library (e.g., Goliath, Hollywood Orchestra) to activate it for the new engine. r2r play opus fixed
: If you recently updated, the Opus installer may fail to remove older VST files. Manually deleting old .vst3 files from your plugin folders ensures the DAW uses the latest Opus.dll or Opus.res . r2r play opus fixed
: Fixed an issue where notes cut off when switching mixer presets. r2r play opus fixed
: Resolved major performance issues and CPU spikes specifically for FL Studio on Windows.
