Finkifized, I completely agree with you. To try to use a tutorial and then not find the file that tutorial is based on really looks stupid. I've jumped on certain people who some in here as new users and then really dump on the software but you're not one of them, you're just frustrated. I think you're making legitimate points. Every piece of music software I've ever used has issues for a new user and I've railed about how can they let this or that go by like that. Overall, this is one of the friendliest and most knowledgable forums around and PG Music is one of the best for customer service. Don't worry we'll get you up and running. Unfortunately I know nothing about your Line6 POD, in the other thread you were having a problem with their ASIO driver. Try using the freebie ASIO4ALL. Just Google it.
Also, everything Rharv and others have said about how RB can do what you want is true once you can get past the intital setup. Just think of this little trick: You've created a tune, recorded some guitar, used maybe 2 or 3 tracks from a midi file, created a few Real Tracks, maybe a few Real Drums using a regular kit along with a separate RD percussion track and you still want to add some piano comping. You can't seem to find a piano RT that works. You can select a style, right click on any empty track and tell it to create a Biab midi piano part using any one of the thousands of styles that have a piano part in them. Some of the Biab midi parts are really very good if you have a decent synth to play them through.
There is no other software that does what RB can do but like anything else, it's not perfect either. It does have some issues with certain things but I'll save that for later.
