How do you make crescendo/decrescendos actually DO what they'res upposed to do? I used the cresc and decresc. markings and I don't think they help. However the sample files show a decrescendo thingy. How do you do that?
You need to anchor them by specifying what dynamic you are crescendoing or decrescendoing from and to - e.g. pp cresc ff or mf decresc p etc. If you don't want these to show, then just make them invisible.
Hope this helps :)
