Playable Midi is a custom timeline/playables package that provides
functionality to control object properties based on sequence data contained
in a standard MIDI file (
.mid file). This allows you to create musically
synchronized animation using a DAW (digital audio workstation) that is easy
to manage accurately synchronized timings compared to other non-musical
timeline editors like Unity’s one. Playable Midi is an extension of the MIDI Animation Track.

Importing .mid files
You can import a
.mid file as an asset file. Simply drag and drop it to the
project view, or navigate to “Assets” - “Import New Asset…”.
An imported asset may contain multiple tracks that are shown as sub-assets under it.
To create a MIDI animation track, drag and drop one of these clip assets to a timeline.
You can animate object properties from a MIDI animation track using track controls. To create a new track control, select a MIDI animation track (not a clip) in the Timeline editor. Then track control editor will appear in the inspector.
A track control only can animate a single property. You can add multiple controls to animate multiple different properties.
At the moment, a track control only supports
Color properties. Please note that it requires a public property to
be animated; Just providing a public variable is not enough.
There are three modes in the track control: Note Envelope, Note Curve and CC.
Note Envelope mode
Note Envelope is a mode where a property is animated by a classic ADSR style envelope. This mode is useful when you want to make animation react to key-off events.
You can specify which Note/Octave the control reacts to. Please note that key velocity affects the envelope. It’s simply multiplied to the envelope output.
Note Curve mode
Note Curve is a mode where a property is animated by an animation curve. It starts playing animation on key-on events and keeps playing until it ends (key-off events will be ignored).
You can specify which Note/Octave the control reacts to. Please note that key velocity affects the animation curve. It’s simply multiplied to the curve value.
CC is a mode where a property is animated by CC (control change) events contained in a MIDI track.
You can specify which CC Number the control reacts to.
A MIDI animation track also supports sending Timeline Signals on key-on/off and some Meta events. To receive MIDI events from a track, you can use the MIDI Signal Receiver component.
- Add the MIDI Signal Receiver component to a game object that receives MIDI signals.
- Specify which Note/Octave the receiver reacts to.
- Register methods to Note On/Off Events.
- Set the receiver game object as the output destination of the track.
