MIDI Fluid Vizualization

A fluid simulation that dances to your MIDI music. Play a MIDI file or a real MIDI instrument and the notes will become visible in the fluid simulation.

Supported MIDI messages: Note on, Note off, Sustain pedal ("Hold"), Sostenuto pedal, All notes off, All sounds off, all Controllers off, Reset

Options

Some options of the app can be configured via URL parameters:

• midiPortName (string; default: undefined): Name of the MIDI input port to grab the MIDI messages from. If not set, a MIDI file player will be made available.
• midiChannelMask (number; default: 1111111111111111): Use the MIDI channels marked with 1, ignore MIDI channels marked with 0. Channel 1 corresponds to the rightmost character, Channel 16 to the leftmost.
• midiVelocityFactor (number; default: 1.0): Factor to apply to the MIDI note velocity.
• midiVelocityOffset (number; default: 0.0): Offset to add to the MIDI note velocity.
• pauseParameterAnimation (boolean; default: false): Pause the built-in animation of the visualization parameters.
• idleTimeout (number; default: 60): Pause the animation after the given number of seconds without input to reduce system load.
• splatGroupSize (number; default: 64): Control how many notes are rendered together. For internal use, mostly.
