# Flex Chorus

***

### Overview

Flex chorus delivers lush stereo widening and an ensemble-like character through two distinct chorus algorithms. With up to 24 voices, integrated multi-band processing, and independent controls for delay time and modulation depth, you can shape everything from expansive unison effects to detailed stereo enhancement.

Both the plugin and the Current effect rack version come with presets ranging from essential stereo enhancement to dense, detuned spaces, and more.

For the preset bar, Settings menu and Global Tune, see [Preset Bar and Settings](/core-effects-manual/effects/preset-bar-and-settings.md).

### 1. Modes

**Voices**. Drag up or down on the number to choose the number of voices. In general, fewer voices will sound more defined but also more obviously detuned, while more voices create a denser, more diffused effect. Note that using additional voices will require more CPU.

**Chorus Mode.**

* **Smooth.** This mode is inspired by classic chorus effects, with a focus on creating a smooth and evenly detuned sound.
* **Glass.** This mode utilizes a clever multi-tap approach to produce a clean and modern chorus effect, with resonator-like feedback.

### 2. Chorus Controls

**Time.** Set the base delay time for the chorus. Higher values will result in larger, more diffused effects, while smaller values can produce a sound that is smaller and more metallic.

**Width.** Adjust the stereo width of the chorus effect. Disabled when the plugin's output is mono.

**Feedback.** Adjust the amount of feedback applied to the chorus. This can be used to create reverb-like tails and metallic resonator effects. Note that the **Smooth** and **Glass** modes have noticeably different feedback implementations.

### 3. Filter & Multi-Band

When active, filters are applied to the signal so that the chorus effect is only applied to a specific part of the frequency spectrum.

**Filter Mode.**

* **Filter.** This mode applies a simple highpass and lowpass filter to the chorus.
* **Multi-Band.** This mode utilizes two crossover filters to preserve the low and high end of the original sound.

**Highpass.** Set the frequency of the highpass filter or low crossover, depending on the current filter mode.

**Lowpass.** Set the frequency of the lowpass filter or high crossover, depending on the current filter mode.

### 4. Modulation

**Modulation Depth.** Adjust the depth of the internal modulation applied to the chorus. Setting this to 0% will enable manual control over the modulated parameters.

**Rate.** Adjust the LFO rate.

**Sync.** Enable BPM synchronization for the LFO rate.

**Randomize.** Adjust the amount of LFO randomization. Note that each waveform randomizes in a unique way.

***

### 5. Utility Controls

**Input Gain.** Adjusts the gain sent into the effect.

**Input Send Button.** When active, the input gain will only affect the signal being sent to the effect, leaving the dry signal unaffected. Try combining this with automation or modulation to send only specific parts of your input through the effect.

**Dry Wet.** Adjusts the balance between the processed (wet) signal and the unprocessed (dry) signal.

**Output Gain.** Adjusts the gain at the end of the effect's processing chain, useful for compensating gain changes or adding creative effects.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://manual.minimal.audio/core-effects-manual/effects/flex-chorus.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
