MidiInput for Unity

MidiInput is a native code plug-in for Unity. It allows Unity to communicate with external MIDI controllers.

Demo

You can find two demo projects in the [test branch] (https://github.com/keijiro/unity-midi-input/tree/test).

Note

The first demo "Note" shows how to get key presses and releases from MidiInput. The size of the cubes are relative to velocity of a key press.

CC

The second demo "CC" shows how to get CC (control change) data from MidiInput.

Function reference

static float GetKey ( noteNumber )

Filters for CC input

You can specify one of the three filter types below when retrieving a CC value with the GetKnob function.

  • Filter.Realtime - no filter. It returns the last received value.
  • Filter.Fast - light low-pass filter. It suits fast-moving objects.
  • Filter.Slow - heavy low-pass filter. Very smooth but not responsive.

You can adjust the sensibility of each filter in the inspector.
