i'm fairly new to the whole home recording environment, so please bear with me here. i'd like to start recording my own songs using my guitar and some type of drum machine software for starters. i have an m-audio jamlab USB device for playing my guitar through my computer using the inTone Express Guitar software, which i've been using for casual jamming and basic recording of my guitar. i also have access to Digidesign Pro Tools M-Powered 7 and SONAR Home Studio 7 software- neither of which i have any real experience in using yet. so here's what i want to do: i'd like to start by recording a basic guitar track, then be able to play the track while recording a new guitar track over top of it, recording both together as one track. i'd also like to be able to add in a drum track, hopefully with the ability to create and edit my own drums tracks to be added to the compositions. i'm hoping someone can point me in the right direction in terms of which software is best to use (with what i have available noted above) and possibly provide me with some general guidance on how to go about this process.
