hint request: custom selection
I need a plugin that selects all the altered notes in a score, whether the alterations are in the key or around the score
In the end I need to be able to select all the notes named C#, D#, E#, F#, G#, A#, B# at he same time or, separately, all the flatted, and double flatted, and double sharpened, instead of selecting each one and extending the selection...
Do you have any hint?
Is there any plugin already available that I can try to modify?
