Groups allow you to sort the articulations in order to prioritize and combine them.

The groups themselves are exclusive. Articulations that are in the same group cannot be used together. You can place articulations that cannot be combined, such as arco (bowed) and pizzicato (plucked) for violin in the same group.

Groups represent the musical importance, with group 1 having the highest priority. This is useful if an expression map does not find an exact match for your data and tries to identify the sound which matches most criteria. If two sounds are found which have the same articulation in group 1, the sound that also matches group 2 is preferred and so on.
