A Chorus is a modulation effect which alters an original signal by creating a slightly delayed and pitch-shifted copy (or copies) of it, to create a subtle difference between the two signals.
Then, the amount of pitch-shift and delay is modulated with an LFO: these gradual changes will impact the pitch of the copied signal.
Finally, the copy is mixed back with the original signal to create the Chorus effect.
The pitch is modulated using an LFO and both depth and rate are used to create varying colors or texture to the effect.
The versatility of the Chorus allows you to thicken and widen a sound, by making it rich and shimmering while it can also push it to the background.
In the music production history, the chorus has been heavily used on guitars, basses and keyboards but many other creative uses are possible, on every kind of audio signal.

1. Mode Switch
Stereo and Mono.When in Stereo, we have full stereo processing. When in Mono, the source signal is "monoized" (Left and Right inputs are summed before processing).
2. Dimension Mode
Changes the original behavior of the compressor/expander stages of the unit, basically changing their time constants.We have four positions. The highest position has lower attack and release values, whereas the lowest position has smoother attack and release values.
Note: This control may sometimes not have a very audible effect on the output, depending on the input material. Although this is a very subtle parameter, it is at the core of the original vintage and "warm" sound.
3. LED VUmeter
Allows you to choose between the 4 recreations of the original modes.When “0 ” is pressed, no modulation will be applied, but only circuitry effect on the dry signal.
Mode 4 is a special button. It doesn't work alone, but in combination with each of the first three. It injects more wet signal in the output.
Therefore, it is basically a gain button applied to the wet signal.
4. Power Button
Turns off the plug-in.In practice, it works as a bypass button, and has the exact same effect as clicking "bypass" in the lower toolbar.

5. Oscillator Shapes
This section presents a row of buttons that allows to select alternative waveforms for the modulation LFO. The default (original) is Triangle - we’ve added Sine, Ramp, Sample & Hold, and Sample & Hold Smooth.Tips: Random waveforms in a chorus unit may seem counterintuitive at first sight, but they can produce interesting results, although somewhat "out of the box".
6. Dynamic Color
Changes the original behavior of the compressor/expander stages of the unit, basically changing their time constants.We have four positions. The highest position has lower attack and release values, whereas the lowest position has smoother attack and release values.
Note: This control may sometimes not have a very audible effect on the output, depending on the input material. Although this is a very subtle parameter, it is at the core of the original vintage and "warm" sound.
7. Width
Controls the wideness of the stereo field of the processed signal.Fully to the right, the processed signal stereo field is wider than the original, while fully to the left the stereo image becomes "monoized".
There is a position labeled "Stereo" which corresponds to the original unit width balance.
Note: The Width control appears only in stereo channels, or when the plug-in is instantiated as Mono-to-Stereo.
When the plug-in is instantiated in mono channels, this control will not be present.
8. Mix
Another control added by Arturia to give extra flexibility to the user: unlike the original unit, you can now mix your dry and wet signals as you wish.If you have any further questions, feel free to contact us.
