OSL Multi Chorus is a digital effect inspired by the topology of four iconic modulation units.

In addition to capturing the sound of the original OSL Chorus, this plugin includes three new modes, each with a distinctive sonic character. Each mode is fully editable, making it possible to create effects ranging from subtle to extreme.

Explore the factory presets or dial in your own chorus to instantly add thickness and width to any source, including guitars, drums, bass, vocals, and synths.


Sixty: The original OSL chorus effect, modelled after the onboard chorus of the Juno-60 synthesiser. It produces rich, wide choruses that are perfect for bringing dry synthesizers to life, but sounds equally good on guitar, bass, and other instruments.

Studio: Inspired by a legendary rack mounted chorus unit that was a staple in recording studios during the 1980s. Subtle modulation and filtered delay lines result in shimmering textures that pair well with guitars and vocals.

Ensemble: A lush chorus created from three delay lines that are phase rotated relative to one another. This topology is found in a number of classic synthesisers, and is perfect for thickening up strings and pads.

Quad: A versatile chorus architecture comprising four delay lines. This mode produces lush, swirling ensembles inspired by a late 1970s string synthesiser.
