OA-Phosphor-1: Free Unstable Analog Synth for macOS by OA-Labs
OA-Phosphor-1 is a free virtual analog synthesizer plugin for macOS from OA-Labs. Its "controllable instability" controls add drift, sag, and wobble to a subtractive-synthesis signal path.
Features and Sound Design
Phosphor-1 combines oscillators, a filter, envelopes, and LFOs with instability controls that can move from subtle variation to detuned, evolving textures.
Formats and Compatibility
The current macOS release is available in AU and VST3 formats. OA-Labs says a Windows version is in testing and provides a waitlist on its website. The vendor does not publish an Apple Silicon-versus-Intel compatibility statement, so check the support page before installing.
Cost, Download, and License
Phosphor-1 is free. The OA-Labs download form requires an email address; submitting it starts the download and also consents to occasional product email.
