Slur Smooth

Slur smoothing rounds voiced pitch transitions at note boundaries. It is most apparent when adjacent notes have different written pitches and the rendered transition sounds too abrupt. Despite its name, it applies to every qualifying note boundary, not only authored slurs. The controls appear in Pitch mode.

When a voiced note boundary contains a written pitch change, this parameter sets the strength of the rounded transition. At 0%, the processor is off. Higher values produce a more continuous transition; excessive values can make an intended step sound delayed or indistinct.

This parameter sets the duration over which smoothing is distributed around the note boundary. Lower values keep the change concentrated near the boundary. Higher values begin the transition earlier and finish it later. If neighboring notes are short, a large window can occupy a substantial part of both notes.

Increase Slur Smooth first when the transition remains abrupt. When the shape is strong enough but too narrow, increase Slur Window. If the pitch change loses rhythmic definition, reduce the window before reducing the strength.
