Subgraphs
Subgraphs let you encapsulate groups of nodes into a single reusable module. Think of them as custom nodes that you design yourself.
What is a Subgraph?
A subgraph is a container node that holds its own internal graph. From the outside, it looks like a single node with input and output ports. Inside, it contains a full node graph.
Creating a Subgraph
- Select the nodes you want to encapsulate
- Right-click → Wrap in Subgraph
- The selected nodes are moved inside a new subgraph node
- Input/output ports are automatically created based on existing connections
Or create an empty subgraph and build from scratch:
- Add a Subgraph node from the Node Palette
- Double-click to enter the subgraph
- Build your internal graph
Subgraph I/O Ports
Use these special nodes inside a subgraph to define its external pins:
| Node | Purpose |
|---|---|
| Subgraph In (Audio) | Audio input port |
| Subgraph Out (Audio) | Audio output port |
| Subgraph In (MIDI) | MIDI input port |
| Subgraph Out (MIDI) | MIDI output port |
| Subgraph In (Data) | Data input port |
| Subgraph Out (Data) | Data output port |
Each port node you add inside the subgraph creates a corresponding pin on the outside.
Editing a Subgraph
- Double-click the subgraph node to enter it
- Breadcrumb navigation shows your current depth
- Click the parent breadcrumb to go back up
Saving Subgraphs
Save subgraphs as .mnsubgraph files for reuse:
- Right-click the subgraph → Save as Subgraph Preset
- Load saved subgraphs from the Node Palette or Explorer
Subgraphs are stored in ~/Music/MManufacturer/MNodes/Library/Subgraphs/.
Use Cases
- Custom instruments:Wrap an oscillator + filter + envelope into a "Synth Voice" subgraph
- Effect chains:Package a reverb + delay + compression chain as a single module
- Reusable modules:Build utility blocks you use across different patches
- Organization:Keep complex patches clean by grouping related nodes
Random Patch Generator
MNodes includes a random patch generator that can create patches automatically:
- Tags: Tone, Drive, Motion, Transform, Space, Dynamics, Weird
- Recipe types: FX Chain or Instrument
- Complexity slider: Control the density of the generated patch
- Options: Create new patch, replace subgraph, or wrap in subgraph
