# Engine View
***
### Overview
The Engine View is where you'll find all of Current's core oscillators, filters and more.
It includes five sound engines, two filters, dedicated FM and mixer panels, a modulation control bar, and a keyboard section with two MIDI effects.
***
### 1. Sound Sources
Current features two wavetable oscillators, a granular engine, an additive sub oscillator, and a time-stretching sampler engine. These sound sources can be navigated by clicking on their respective tabs.
Each sound source tab includes one or two buttons with icons corresponding to tab's sound sources. Clicking this icon toggles the sound source on or off. Command-click (macOS) or Ctrl-click (Windows) on the tab icon to solo a sound source. Right-click the icon to access solo and direct out options.
Learn more about each sound source here:

2. [Granular Engine](/current-manual/sound-engine/granular-engine.md)
3. [Sub Oscillator](/current-manual/sound-engine/sub-oscillator.md)
4. [Sampler Engine](/current-manual/sound-engine/sampler-engine.md)

### 2. Filter, FM & Mixer
Current features two multi-mode filters, a flexible FM system, and an engine mixer panel. Click on a panel tab to open it for detailed editing.

2. [FM Panel](/current-manual/sound-engine/fm-panel.md)
3. [Mixer Panel](/current-manual/sound-engine/mixer-panel.md)

### 3. Modulation Control Bar
The modulation control bar, located at the center of the Engine View, lets you easily assign modulation via drag and drop, access the mod matrix for detailed editing, swap modulator types, and open individual modulator panels .
Learn more about the modulation system here:
1. [Modulation System](/current-manual/modulation.md)
2. [Mod Matrix](/current-manual/modulation/mod-matrix.md)
***
### 4. Keyboard Area
Current’s keyboard area features an arpeggiator and chord generator for quickly creating melodies and chord progressions.
On the right side of the keyboard, you'll find the key and scale selectors. Aligning these with your track ensures that the arp and chord modules will always play in key.

## 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/current-manual/overview-and-navigation/engine-view.md?ask=&goal=
```
`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.
