# Curve Sequencer

###

### Overview

The Curve modulator in Rift provides two independent Curve modulators that let you create custom modulation shapes using a variety of draw tools and precise editing features, or load existing ones from a substantial preset library. It is versatile enough for both sequencing and LFO-style tasks, capable of producing looping and one-shot LFOs, complex sequences, and rhythmic patterns. Use the shape tools to build patterns, generate random shapes, and save sub-presets for reuse.

### 1. Curve Presets

The **Curve** modulator supports sub-presets you can save and load from the top-right bar of the panel. Plenty of presets are included, and you can easily save and reuse your favorite modulation shapes.

Click **Shuffle** on the left side of the preset bar to load a random preset.

### 2. MIDI Retrigger&#x20;

Choose how the Curve react to incoming MIDI signal.

* **Off.** Standard Looping Curve with no retriggering.
* **Purple.** Incoming MIDI notes retrigger the looping Curve.
* **Orange.** Incoming MIDI notes retrigger the Curve as a one-shot envelope.

### 3. Curve Controls

**Rate.** Sets how the modulation speed is defined. Enable BPM sync to lock it to the project tempo. When disabled, the rate is measured in Hz.

### 4. Curve View and Draw Tools&#x20;

Click on the Open the Curve View Icon to open a secondary view with in-depth Curve editing and sequencing controls.

**1.- Rate.** Sets how the modulation speed is defined. Enable BPM sync to lock it to the project tempo. When disabled, the rate is measured in Hz.

**2.- Undo.** Undo the last change made in the Curve editor.

**3.-Horizontal Grid Division.** Choose how the editor is rhythmically divided.

* **Standard.** Divisions by two.
* **Triplet.** Triplet-based divisions.
* **Odd.** Non-standard divisions that are neither standard nor triplet.

**4.-Vertical Grid Division.** Controls how the modulation range is divided in the editor. This helps snap the Curve to precise values. Divisions are set in powers of two.

**5.-Clear Curve.** Click the **Eraser** icon to reset the current **Curve** shape.

**6.-Snap to Grid.** Click the **Magnet** icon to enable or disable snapping to the grid when dragging.

**7.-Randomize Curve.** Generate modulation shapes that fit into the current **Grid Division** settings.

{% hint style="info" %}
Right-click **Randomize** to select a specific type. Try changing grid sizes to influence the results.

* **Random Shape.** Picks from any of the types below.
* **Smooth.** Sine-like curves.
* **Linear.** Triangle-like ramps.
* **Chaos.** Complex, less grid-bound shapes.
* **Steps.** Step-sequencer patterns.
* **Segments.** Mixed steps and linear ramps.
* **Gates.** On/off sequences.
* **Ramp Down.** Downward stabs and sweeps.
* **Ramp Up.** Upward pumps and sweeps.
  {% endhint %}

8. **Draw Tools.** Use them to create custom modulation shapes. It allows manual drawing and editing; other tools create shapes based on the current grid settings.

With the **Mouse** tool selected, you can select one or more points and use these commands:

* **Move Off Grid.** Hold **Shift** while dragging a point.
* **Straighten Curve.** **Shift-click** a line or selection.
* **Move Segment.** **Command-drag** (macOS) or **Ctrl-drag** (Windows) on a line.
* **Delete Point.** **Double-click** a point.

**Slope.** Adjust the curvature of the selected draw tool.
