For those wishing to combine musical writing score of formalization and immediate listening results, GP6 meet their expectations. The handling is very intuitive and they quickly come to formalize small (or large) projects. A lot of work has been done on the sounds, effects and guitar amp relating thereto. GP is oriented guitar and I would have liked a bit more of his other instruments but I guess for the following versions it develops. In short, guitarists who are looking for software that will allow you to format your songs to listen to them with the quality, exchange and / or find on the net and all for about fifty, please !
