OA-Labs Phosphor-1 v1.1 Adds CLAP, Windows Support, New Arpeggiator
OA-Labs has released Phosphor-1 v1.1, a major update to its free virtual analog synthesizer built around controllable instability. The instrument now runs on Windows via VST3 and adds CLAP support alongside the existing macOS AU version, making it fully cross-platform.
What Changed in v1.1
The headline addition is native Windows support (VST3) and the CLAP plugin format, closing the platform gap from the initial macOS-only release. The arpeggiator has been completely reworked with three new creative tools: a Trig Phase parameter for Elektron-style cycle/phase control, per-step octave motion, and a per-step glitch effect that introduces jump and stutter variations. OA-Labs also added 20 new factory presets, preset import/export for sharing patches, and assorted stability fixes.

- Formats: VST3, AU, CLAP
- Platforms: Windows 10+ (64-bit), macOS 11+ (Apple Silicon & Intel)

Who It's For
Phosphor-1 targets producers who want analog-style drift and character without paying for commercial VA synths. The instability engine lets you dial in oscillator drift, filter variance, and envelope jitter per voice — useful for lo-fi textures, evolving pads, and gritty basslines. The new arpeggiator features push it further into live performance and generative territory.
