Scalar

• PChanged: Outputs a 1 if the value of the input pattern has changed,
• PDiff: Outputs the difference between the current and previous values of an input pattern
• PSkipIf: If skip is false, returns input; otherwise, returns None.
• PNormalise: Adaptively normalise input to [0..1] over a linear scale.
• PMap: Apply an arbitrary function to an input pattern.
• PMapEnumerated: Apply arbitrary function to input, passing a counter.
• PScaleLinLin: Map input from linear range [a,b] to linear range [c,d].
• PScaleLinExp: Map input from linear range [a,b] to exponential range [c,d].
• PRound: Round input to N decimal places.
• PScalar: Reduce tuples and lists into single scalar values,
• PWrap: Wrap input note values within , .
• PIndexOf: Find index of items from pattern in
