Anybody using Pro Tracks Plus? I have a Digitech GNX4 and it came with ProTracks Plus. I have started to try and use it but I am having a hard time finding a good comprehensive book or website that has tutorials or written information. Also would anybody recomend a different version of recording software that will work with My GNX4. I want to be able to record small bits of a song and then put them all together with drums etc.
