Musescore Review
I just downloaded Musescore yesterday. It is really good! You can do lots of things with it, even stuff I didn't know you do on a piano! It has every thing from Glissandos to Tremolos, from Triplets to Nontuplets! It is awesome compared to the stuff that costs £700 like Sibelius or Finale. I am working on a song called Ice Kingdom. It is going along very quickly. Some times it crashes (like when you try to do lots of quick notes), but it doesn't lose much data. I definitely recomend that you would buy it.
