Working with Nodes

Nodes are the core building blocks of MNodes. This guide covers everything about adding, configuring, and managing nodes.

Adding Nodes

• Right-click on the canvas to open the Node Palette
• Search by name (e.g., "filter", "lfo", "delay")
• Click a result to place the node at the cursor position

Selecting Nodes

Action	Input
Single select	Click on a node
Multi-select	Ctrl/Cmd + click
Box select	Click and drag on empty canvas
Select all	Ctrl/Cmd + A
Deselect all	Click on empty canvas

Moving & Resizing

• Move: Click and drag selected nodes
• Resize: Drag the edges or corners of resizable nodes (some nodes like widgets are resizable)
• Arrow keys: Nudge selected nodes

Copy, Paste, Duplicate

Action	Shortcut
Copy	Ctrl/Cmd + C
Paste	Ctrl/Cmd + V
Cut	Ctrl/Cmd + X
Duplicate	Ctrl/Cmd + D
Delete	Delete or Backspace

Pasted nodes retain their parameter values and internal state. Connections between copied nodes are preserved.

Node Parameters

Select a node to view its parameters in the Inspector panel on the right.

Parameter Types

Type	Widget	Description
Continuous	Knob / Slider	Float values (frequency, gain, etc.)
Discrete	Dropdown	Choose from predefined options
Toggle	Button	On/off state
Trigger	Button	Fire a one-shot event
Text	Text field	String input
Color	Color picker	Choose a color
File	File browser	Select a file from disk

Parameter Features

• Lock: Protects a parameter from the section's randomize function. The parameter can still be changed manually, via presets, or via its own individual randomize button. Only visible in the Inspector
• Expose to DAW: Make a parameter available for DAW automation (see Automation)
• Min/Max/Default: Each parameter has defined ranges
• Step size: Some parameters snap to discrete steps

Node Presets

You can save and load the state of individual nodes:

1. Select a node
2. In the Inspector, use the Node Preset picker
3. Save the current state as a node preset (.mnnpreset)
4. Load previously saved node presets
5. Set a default preset for each node type

Node presets are stored in ~/Music/MManufacturer/MNodes/Library/NodePresets/ organized by node type.

Undo / Redo

All node operations support undo/redo:

• Undo: Ctrl/Cmd + Z
• Redo: Ctrl/Cmd + Y

This includes creation, deletion, movement, resizing, and parameter changes.
