About:

This utility is particularly useful for testing MIDI setups or for users without access to a physical MIDI keyboard.

  • Virtual onscreen keyboard interface
  • Support for MIDI note input and control changes
  • Selectable MIDI output ports for routing
  • Customizable velocity and octave settings
Use Cases:

  • Virtual MIDI Piano Keyboard (Linux) – A similar tool for Linux environments, often requiring specific MIDI backend configuration.
