Node Editor
Visual programming environment for creating effects
Node Editor
The Node Editor is where you create effects using visual programming. Connect nodes to build anything from simple color washes to complex generative patterns.
Interface
Canvas
The main area where nodes live. You can:
- Pan by scrolling (scroll wheel or trackpad)
- Zoom with pinch gesture or Cmd + scroll
- Select nodes by clicking them
- Drag on the background to create a selection box
Effect Selector
The toolbar includes an effect selector dropdown that lets you switch between effects, create new effects, or import effects from the library. Open it by clicking the dropdown or pressing Cmd + P.
Toolbar
- Clean Up - Auto-arrange node layout
- Copy - Duplicate the current effect
- Rename - Rename the current effect
- Delete - Delete the current effect (disabled if in use)
- Export - Export the effect to a file
- Category - Set the effect category
Node Browser
Access by pressing Shift + A or right-clicking the canvas.
Working with Nodes
Adding Nodes
- Right-click on the canvas
- Browse categories or search
- Click a node to add it
- The node appears at your cursor position
Selecting Nodes
- Click a node to select it
- Shift + Click to add to selection
- Drag a box to select multiple
- Cmd + A to select all
Moving Nodes
Drag selected nodes to move them.
Deleting Nodes
Select nodes and press Delete or Backspace.
Connections
Making Connections
- Click an output port (right side of node)
- Drag to an input port (left side of another node)
- Release to connect
Or drag from input to output—direction doesn't matter.
Connection Types
Connections are color-coded by data type:
- Gray - Number
- Purple - Vector
- Blue - Color
- Green - Boolean
Breaking Connections
- Click a connection and press Delete
- Drag from a connected input to disconnect
- Right-click a connection and select Delete
Connection Validation
You can only connect compatible types. Invalid connections show a warning.
Node Types
Input Nodes
Provide values to your effect:
- Number - Constant numeric value
- Color - Constant color
- Time - Animated time value
- Fixture Index - Per-fixture index
- Pixel Position - Position map coordinates
Processing Nodes
Transform values:
- Math - Arithmetic operations
- Color - Color manipulation
- Wave - Oscillators and generators
- Comparison - Logic operations
Output Nodes
Send data to fixtures:
- Output - Sets the final color output for the effect
Parameters
When a node is selected, its parameters appear in the Parameters panel:
- Adjust values with sliders or number inputs
- Some parameters can be connected to other nodes
- Default values are used when no connection exists

Tips
Organization
- Use comments to document complex sections
- Align nodes for readability
- Group related nodes together
Performance
- Fewer nodes = faster effects
- Avoid redundant calculations
- Use the simplest node that works
Debugging
- Check connection types
- Verify parameter values
- Use preview to see intermediate values
