Further i don't understand how to determine in the composerscreen what is a unique copy or a shared copy ?
This text is in the docummentation but helps me not further i don't get it:
The composer draws the parts with a subtle 3D effect: when a part is drawn 'down', then it's a unique part i.e. it's the only part using that sequence. When a part is drawn 'up', then it's a shared part i.e. there are more parts (may also be in other compositions in this session) playing that sequence.
Further about merging parts : what are the conditions for this in relation to copied or shared parts
Unique part copies seems to me possible to merge..what about the shared parts?
