I love guitar sounds, some friends of mine play guitar and they are always searching for applications to improve their songs. So, recently they have found the Tuxguitar!
If you are a guitar lover, probably you have heard talking about the Guitar Pro, but there is a free alternative to it, the Tuxguitar and is a multitrack guitar tablature editor and written in Java language. So, this free tool will go to help those that like to compose music in an easy and faster way.
