Post Description

There are many different chorus effect plugins available on the market today. However, finding one which gives the classic analog chorus sound is easier said than done. Even on expensive units with advanced parameter controls, getting that vintage chorus timbre can be a challenge.

With this in mind, D16 set out to create a plugin which would have a rich analog chorus similar to the effect found on classic synthesisers like the Solina, Synthex or Juno. This new effect is called Syntorus and is the latest addition to the Silver Line of plugins.

Syntorus has a unique sound which will add richness to any instrument it is used on. Synthetic basses and leads will come to life. It will also add extra depth and lushness to acoustic instruments.

Now for the science... To create a chorus effect, an audio signal is mixed with one or more delayed, pitch modulated copies of itself.

Analog Delay Line
The delay line module is the most important part of any chorus unit. To give Syntorus its unique and special sound, we implemented a very precise model of a high quality analog delay line and projected this into the digital domain. This means that Syntorus has a very musical and warm sounding delay line with no unwanted digital artifacts.

Syntorus also has an emulation of a Bucket-Brigade Device (BBD) analog delay line included within its architecture. Turning this on, will add extra analog warmth and character to the audio signal. With BBD off, Syntorus functions as an exceptional high quality chorus effect unit where the spectrum of the sound is clean and pristine.

Double Delay Line
In most ordinary chorus effect units, a single delay line is used to create the sound.

As Syntorus is no ordinary plugin, we decided to implement TWO high quality analog delay lines to give a richer, fuller and deeper chorus sound. These can be set to operate separately or configured to run in a master/slave mode. Full control is provided over all parameters in the signal path allowing for absolute freedom when sculpting the sound.

Tremolo
Both delay lines have an additional tremolo effect included which is controlled by a LFO - very useful for playing Rhodes keyboards or guitar sounds.

The Tremelo effect can be used on its own or added to the delay line signal to create even more dynamic and moving sounds.

Complete Synchronization of LFO with Hosting Application
Each LFO can be synchronized with the host application. In this mode the period of the LFO depends on the host tempo and is set as a musical measure. This feature is standard on most plugins. However in Syntorus, the phase is also perfectly synchronized with song position within a project. This guarantees that Syntorus will always play exactly the same way wherever we are in the timeline of a song or project.

Characteristics
Comparison of two different chorus units (one of them is Syntorus). Take a closer look at the comb filter (more regular and accurate), which is the result of the convolution of two spectrums: input signal and phase shifted signal.
