Chorus RA-1
Chorus RA-1 brings a stereo richness that's genuinely rare to find in a plugin.
Built around the warm, slightly imperfect character of classic analog BBD chorus units, RA-1 keeps things simple: no walls of parameters, just the essentials for wide, warm sound. That beautiful stereo width and easy control layout is the whole point.
Two voices moving in opposite directions, driven by a skewed triangle-wave LFO, give RA-1 its signature sweep — a fast dip followed by a slow, developing recovery. RATE and DEPTH shape it, PHASE spreads it across the stereo field, and MIX brings it all together. Four knobs, instant results.
A go-to mixing essential
There's chorus, and then there's RA-1. This isn't just another stereo widener — it's the kind of tool that ends up on nearly everything, and once you hear what it does to a mix, you'll understand why.
Drop it on a Rhodes and a flat patch suddenly breathes. Run it across a guitar bus and things feel wider, deeper, without losing punch in the center. Even a plain synth pad picks up motion it didn't have before — subtle enough to sit quietly in a mix, but the moment you bypass it, you feel exactly what's missing.
