This paper presents the recent developments dealing with our metrical score representation format and how it can be used to produce and manipulate musical scores in PWGL. The base of these ideas is a special score format, called ENP-score-notation, that allows to describe in textual form various score elements like beats, measures, voices and parts. This basic format can be extended using keywords to represent other score attributes such as pitch, enharmonics, expressions, and so on, resulting in complete scores. A novel PWGL library, KSQuant, uses a similar format: instead of the tree-based representation of the metric structure, KSQuant uses a flat onset-time representation. This format is ideal for many types of score manipulation operations where it is essential to preserve all score attributes.
