Installation
Bellweather plugins support a dual install path - use whichever method fits your workflow. Weather Station is a free app that handles downloads, updates, and licensing in one place. Or use a standard macOS package installer for each plugin. No lock-in either way.

DAW Plugin Scanning
Format note: Logic Pro uses AU only. Pro Tools uses AAX only. Most other DAWs use VST3 (also support AU). All three formats are installed - your DAW will find the right one.
Logic Pro (AU only)
Logic scans automatically on launch. If the plugin does not appear, go to Logic Pro, then Settings, then Plug-in Manager, then Reset & Rescan. If Logic shows a validation error, open Terminal and run auval -v aufx BWxx BWst to check. Contact support with the output.
Ableton Live (VST3 or AU)
Go to Preferences, then Plug-Ins, then enable VST3 or AU. Click Rescan.
Pro Tools (AAX only)
Restart Pro Tools. It scans for new AAX plugins on launch. For issues, verify the plugin exists in /Library/Application Support/Avid/Audio/Plug-Ins/.
Cubase / Nuendo (VST3)
Go to Studio, then Studio Setup, then VST Plug-in Manager, then click Rescan All.
Reaper (VST3, AU, or CLAP)
Go to Options, then Preferences, then Plug-Ins, then VST, then click Re-scan. Reaper also discovers CLAP plugins from the standard CLAP directory automatically.
FL Studio (VST3)
Go to Options, then Manage plugins, then click Start scan.

Go to Studio One, then Options, then Locations, then VST Plug-Ins. Click Reset Blacklist, then Rescan.
