With so many chorus effect plugins on the market, finding one capable of delivering a truly authentic analog sound is easier said than done.

With that in mind, D16 Group set out to create the ultimate analog chorus emulation, inspired by the revered effects found in classic synthesizers such as the Solina String Ensemble, Elka Synthex, and Roland Juno-106. The result is Syntorus 2, the latest addition to the Silver Line plugin series.

Syntorus 2's unique analog sound enriches any routed instrument, bringing bass and synth leads to life and adding depth and richness to guitars and other electric/acoustic instruments.

Download the demo and try Syntorus 2 for yourself. No matter what kind of music you make, this is the analog chorus plugin you've been looking for!

Now for the science...

Chorus with a real analog feel

The classic chorus effect is created by mixing an audio signal with one or more delayed and modulated copies of itself. It follows that the delay line module is the most important part of any chorus unit. For Syntorus 2, D16 Group built an extremely accurate model of a high-quality analog BBD (bucket brigade device) delay line in the digital domain: the resulting emulation has an incredibly warm musical sound without unwanted digital artifacts.

Three BBD delay lines

Most chorus effect units use a single delay, but Syntorus 2 deploys three analog delay lines to evoke a richer, fuller, and deeper chorus sound. It also gives you the option of choosing between two BBD delay line models: by default, the chorus effect is exceptionally clean and pristine, but enabling the analog BBD emulation adds even more warmth and analog character to the signal. And needless to say, it gives you full control over every delay line parameter, providing absolute freedom to sculpt your sound.

Configurable Modulation

Syntorus 2's three LFO generators serve as flexible modulation sources, routed to the delay lines in a series of switchable topologies. Timeline-locked host sync and independent left/right phase offset adjustment further expand the spectrum of creative possibilities.

Filter and tremolo

Each delay line has a built-in multimode filter and tremolo effect, both controlled by the same modulation sources as the delay time. The filter is ideal for producing convincing Leslie sounds, especially when delay modulation is used to simulate the directional characteristic and Doppler effect of a rotating speaker. The tremolo can be used on its own or added to the modulated delay line to create even more dynamic sounds; it is particularly effective on keyboards and guitars.

Full sync

Each LFO can be independently synced to the host DAW, allowing you to set the rate to musical note values at the project tempo. That in itself will not be a surprise, of course, but with Syntorus 2, the phase is also perfectly synced with the playhead position within your project, ensuring that your chorus always sounds exactly as it should at any point on the timeline.
