MIDI Humanize

Loosens mechanically precise MIDI playback by adding subtle timing and velocity variation. Timing jitter is applied around a delayed center so it stays causal, and velocity is nudged within a configured amount to break up uniform dynamics. The result feels more like a human performance without drifting out of time.

Parameters

Timing Spread (late)

• ID: timingMs
• Type: float
• Control: slider
• Range or Options: 0 to 50 ms, step 0.1
• Default: 0
• Description: Maximum random delay added to each note. Causal: live notes are pushed later only, never earlier.

Velocity Jitter

• ID: velocityJitter
• Type: int
• Control: slider
• Range or Options: 0 to 32 midiVelocity, step 1
• Default: 0
• Description: Random note-on velocity offset applied within the configured jitter range.

Probability

• ID: probability01
• Type: float
• Control: slider
• Range or Options: 0 to 1 phase01, step 0.01
• Default: 1
• Description: Chance that an incoming note event is humanized instead of passing through unchanged.

Seed

• ID: seed
• Type: int
• Control: numberInput
• Range or Options: 0 to 65535 count, step 1
• Default: 0
• Description: Deterministic random seed for repeatable timing and velocity variation.
