MidiControl Plugin Documentation

Introduction

The MidiControl plugin enables you to connect a MIDI device to Blender and control the values of objects (e.g., location, rotation, scale) or any other numeric input — including geometry nodes, brush settings, and more — via your MIDI controller’s inputs.

Functionalities

1. Property Mapping

The plugin supports two distinct mapping methods:

Method 1 – Object Property Mapping

Used for mapping properties shared by multiple objects in Blender.

Steps:

1. Move the MIDI control you wish to assign on your MIDI device.
2. Adjust the value of the desired property in Blender.
3. The plugin automatically detects the last property you changed. Click the Map button.
4. Set the mapping name, along with the minimum and maximum values.
5. The property is now linked to your MIDI control.

Note: Changes apply only to the currently selected object(s) in the viewport. You may select one or multiple objects to affect.
This method cannot be used for brush properties or other specialized values like geometry nodes. Use Method 2 for such cases.

Method 2 – Direct “Full Data Path” Mapping

Ideal for mapping a specific property of a single object, independent of which object is selected.

Steps:

1. Move the MIDI control you wish to assign on your MIDI device.
2. In Blender, right‑click the property you want to map and select Copy Full Data Path.
3. The plugin detects the copied data path. Click the Map button.
4. Set the mapping name, along with the minimum and maximum values.
5. The property is now linked to your MIDI control.

Tip: This method also works for brush settings, geometry nodes, and other changeable Blender properties.

2. Selection Groups

Create groups of objects that can be selected instantly via a mapped MIDI control button. This allows rapid switching between object sets during a workflow.

3. Resolution Control

Adjust the granularity of property value changes.
You can map two MIDI controls to act as Fine and Coarse resolution factors, which are multiplied by the main MIDI input to refine control sensitivity.

4. Keyframe Insertion

Bind a MIDI button to insert a keyframe for all mapped properties of the currently selected object.

5. Frame Control

Use a MIDI control to navigate the timeline by adjusting the current frame position.
