guitar pro 5 is great for creating music. it isn't free but if you are familiar with guitar tablature, this is a great tool for creating complete songs and also supports percussion instruments. i use it to create my drum beats for my songs, then i simply press play and record the beats in audacity using the "what you hear" speaker output as my recording method.
