Update: added harp/celeste and modified Arco for strings.

I added both the harp and the celeste in the same file because their first 3 techniques are the same.

Symbols used:
- The damped sign (bass muffle) is supposed to be a cross within a circle like a coda but smaller. Notion doesn't seem to have it in any shape or form so I replaced it on the circle sign for strings harmonics.
- The plus sign is an actual symbol for harps indicating a damped played note. It was added as it is. Being less stronger than a muffle, it's mapped on the damped medium.
- The bisbi-gliando trem was put on the tremolo sign.
- And finally the gliss FX is on the 'doit' sign available through a Shift + U shortcut.


I wasn't satisfied with the Arco. Being a symbol only used by strings and indicating it should be bowed (played with the bow), I gave it the same behaviour as the main/normale.

Please find the newest files along with this post.

The percussion should come early next week.

After that, I will take a round to adjust different volumes by checking some players videos. For instance, I am not sure if the flute marcato is supposed to be that quiet compared to a normal long note.

Then I will get on the experimental stuff, starting with the left hand pizzicato. I will probably mix two techniques for this one, a shorten pizz. + short harmonics.

Great to see more work on the Rules I started, will test. I don't use BBCSO much at all these days except for percussion and harp.
