# Signal Flow

<figure><img src="/files/Pyl0Ov1yx9V8VpcVvQFe" alt=""><figcaption></figcaption></figure>

Rift’s signal flow allows for some exciting and unconventional processing. This section is a short overview, and you will find more detail in each module’s respective section.

1. **Drive.** Rift’s processing begins with input gain controls. These are useful for driving the signal to produce more intense distortion or creating rhythmic effects when modulated.
2. **Distortion.** The distortion engine blends two parallel algorithms in Rift’s unique waveform processor. Here you can create custom effect combinations with precise control over how they are mixed. Easily choose the number of stages to take Rift from subtle to extreme.
3. **Feedback.** After the distortion, the signal is sent through a flexible feedback processor. The feedback’s frequency range can be set to notes, comb filtering, or longer delay times.
4. **Filter.** Rift’s filter can be routed pre distortion or post feedback. Choose from 24 custom filter types ranging from morphing, formant, notch, harmonic, and more.
5. **Output.** Here you can adjust the output gain, select an output limiter, and control the global dry/wet.
6. **Modulation.** In the center of Rift’s **Engine View,** you will find an envelope follower, a morphing LFO, two powerful Curve modulators, and two macro knobs. These can modulate any parameter, but they do not produce sound on their own.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://manual.minimal.audio/rift-manual/welcome-to-rift/signal-flow.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
