OSL Multi Chorus, four vintage-inspired chorus effects in one plugin

OSL Multi Chorus is a new effects processor for macOS and Windows that features four vintage-inspired chorus timbres in one plugin.

Chorus effects are among the most popular FX, alongside delays and reverb. Add them to a synth sound, and you have a fatter, juicer sound in seconds. Many chorus types originated from vintage devices, such as the legendary Juno 60/106. 

Oblivion Sound LAB (OSL), the developers of the excellent Hex Drum Simmons SDS drum synth plugin, have today published an effects plugin that takes you on a journey through different chorus types. 

OSL Multi Chorus

Multi Chorus is a new chorus effects plugin for macOS and Windows inspired by four iconic modulation units.

Sixty is modeled after the onboard chorus of the legendary Roland Juno-60 Synthesizer. This is also available in the free OSL Chorus plugin. It produces rich, wide chorus that fits perfectly with synths, guitar, bass, and other instruments.

Then, Studio is inspired by a legendary rack-mount chorus unit, a staple in recording studios during the 1980s. I’m not sure, but it could be one of the famous Boss rack units like the CE-300/RCE-10 or the Roland Chorus Echo  –> (edit) Almost, it’s the Roland Dimension D.  It combines subtle modulation and filtered delays, resulting in shimmering textures. 

The ensemble is another lush chorus created from three delay lines that are phase-rotated relative to one another. This is not an emulation of a vintage unit, but you can find this topology in many classic synths. It works great for thickening up strings and pads.

Quad, on the other side, is a versatile chorus architecture with four delay lines. This mode produces lush, swirling ensembles inspired by a late 1970s string Synthesizer.

Multi-Chorus offers a wide range of parameters for each algorithm. You get rate, depth, and delay for the chorus, vibrato with rate and amount control, mixer with high and lowpass filters, and a spread function on the output. There are also left/right output meters and a phase meter.

Further, it comes with 77 factory presets and of course, you can also save your own patches. Oblivion Sound Lab promises the plugin is low on CPU.

First Impression

A nice sounding, easy-to-use chorus effect plugin. I’m a big fan of their Simmons emulation, so I’m excited to see how I like the new Multi-Chorus plugin. 

OSL Multi-Chorus is available now for an introductory price of $35 instead of $49. It runs as a VST3, and AU plugin on macOS (native Apple Silicon + Intel) and Windows.
