Velocity — Expert Mode

First match the velocity curve and range to your playing. The additional controls below help address differences between keys or refine the detection of an attack.

Per-key sensitivity

Press Learn, play the key you want to adjust, then use + / − to change its sensitivity between 50 and 200%. This lets you compensate for a key that consistently plays softer or louder than its neighbours.

Manual overrides lists the individual adjustments. Reset all overrides returns every per-sensor sensitivity to 100% after confirmation.

Detection

Onset filter

Control	Effect
Onset LP Alpha	Smooths the sensor signal before the press is timed. Lower values smooth more but follow movement more slowly; higher values respond more directly.
Onset Hysteresis (%)	Adds a margin around the detection thresholds to reduce repeated crossings caused by small signal fluctuations.
Median	Filters isolated outliers using the last three samples.
Direction Gate	Ignores sample movement against the press direction to stabilise trigger detection.

Strike analysis

Control	Effect
Velocity Character	Blends from an average press-speed response at 0 towards a peak-speed response at 1. Higher values give short, sharp attacks more influence on velocity.
Peak/Avg Slope Cap	Limits how much a brief speed peak can exceed the average speed. It matters when Velocity Character uses the peak; the counter shows how often the limit was reached in the last 100 notes.
Bounce reject	Excludes movement below the progress threshold from the measured press time; 0 disables it. Too high a value can also exclude genuine slow movement and make a soft press louder.

Velocity Character and Peak/Avg Slope Cap do not affect velocity when the Hammer model is active, because that model uses the virtual hammer's speed.

Hammer model: Advanced

These controls appear in Hammer model → Advanced when the Hammer model is enabled. The regular Hammer model controls describe the choice of trigger method and its playing response.

Control	Effect
Hammer inertia	Controls how quickly hammer speed follows key movement. More inertia reduces the effect of very short jolts and can reduce the maximum velocity reached.
Contact tolerance	Changes when a stroke is reported as a hammer throw in the analysis. It does not change note timing or output velocity.
Velocity window	Sets the time window used to estimate key speed. Shorter windows react more quickly to changes; longer windows smooth them more.
