What is MIDI Velocity? In standard MIDI programming, velocity ranges from 1 to 127, indicating how hard a key is struck. Human players do not play with identical force—adding minor variations makes electronic loops sound organic instead of like a machine.
Methods for Humanizing MIDI Velocity
Generate velocity curves to humanize MIDI clips with live bar displays and exportable midi files.
MIDI patterns generated entirely on grids sound cold. Music humanizers introduce timing offsets or velocity deviations to emulate a real keyboardist or drummer:
- Gaussian Distribution (Box-Muller): Creates a classic bell curve where velocity shifts mostly stay near standard average levels, with occasional larger variations. Excellent for subtle hi-hat loops.
- Downbeat & Accent models: Automatically applies heavy weight to bar lines (such as beats 1 and 3) while randomizing ghost notes. Emulates natural human arm swinging and rhythmic breathing.
- Groove Accent offsets: Syncopates other steps (like offbeat hi-hat pulses) to add swing and swing shuffle character.
Frequently Asked Questions
What are velocity curves types?
Uniform (standard human variance), Gaussian (bell curve natural dynamic limits), Human (heavier accents on main grid boundaries), Groove (syncopated offset rhythms), and Accent.
