how do i plot a linear function of f(x) = x in fl studio?

Good question — plotting a mathematical function like ( f(x) = x ) inside **FL Studio** is a little different from doing it in a math app. There’s no built-in “graphing calculator,” but you *can* visualize or recreate the shape of ( f(x) = x ) in a few ways depending on what you want to do:

---

### 🎛️ **1. Using the *Fruity Formula Controller***

This is the easiest and most direct way to plot ( f(x) = x ).

#### Steps:

1. **Add a Formula Controller:**

   * In the Channel Rack → Add → **Fruity Formula Controller**.

2. **Open its editor:**

   * Click the channel → a small window opens with a formula box.

3. **Enter the formula:**

   * In the formula box, type:

     ```
     x
     ```

     That’s literally the formula ( f(x) = x ).

4. **Preview the shape:**

   * The graph in the plugin will now show a straight diagonal line from bottom-left to top-right — that’s your ( y = x ).

5. *(Optional)* Use the output to control parameters:

   * You can link this controller to automate volume, filter cutoff, etc.
   * Right-click a knob → “Link to controller…” → choose the Formula Controller.

### 🧩 **2. Using an Automation Clip**

If you just want to *see* or *use* the linear ramp:

1. Create an automation clip (e.g., for volume or any parameter).
2. In the Playlist, right-click the envelope → choose **“Edit events”**.
3. Draw a straight line from bottom to top — that’s effectively ( f(x) = x ) over time.

You can make it exact by:

* Right-click → “Articulator” → “Init song with this position” → adjust to be linear.

---

### 🎚️ **3. Using an Envelope Controller**

You can also use **Fruity Envelope Controller**:

1. Add it from the Channel Rack.
2. In the envelope section, set two points:

   * Left point: bottom-left (0, 0)
   * Right point: top-right (1, 1)
3. This produces a linear curve — same as ( f(x) = x ).

### 🧠 Summary

| Goal                              | Best Tool                     | Formula                |
| --------------------------------- | ----------------------------- | ---------------------- |
| Visualize or generate math shapes | **Fruity Formula Controller** | `x`                    |
| Use as automation (ramp)          | **Automation Clip**           | Linear ramp            |
| Create mod envelope               | **Envelope Controller**       | Straight line from 0→1 |

Would you like me to show how to make a *custom function* (e.g., ( f(x) = x^2 ) or ( f(x) = \sin(x) )) in the Formula Controller next? I can show how to shape or modulate it visually.
