In the Getting Started book, the three most common Quantizing Types are described: Over Quantize, Iterative Quantize and Groove Quantize. There are two other types available on the Functions menu:
Note On QuantizeThis function quantizes the start positions of the notes just like Over Quantize, but doesn’t move the end positions. In effect, this means that the note lengths are adjusted.
Analytic QuantizeThis is a special Quantizing method, intended for rhythmically complex material. You may for example use this on music that consists mainly of straight notes, but also contains some triplets, trills or glissandos. Analytic Quantize uses the Quantize value, but doesn’t touch notes that are considered “too far” from the Quantize value.
