I understand about audio sound samples - but it's the way they are used and some things just don't work and thus there is a need for a different method. You can sample an instrument up and down the range but it doesn't mean that it sounds natural when used, e.g. rhythm guitar. Most of the time I think they sound poor for obvious reasons. My understanding is that Real Tracks works a little differently in that it takes little phrases and pieces them together smartly so things sound much more natural than the "endless loop" style that you hear with most sample rhythm guitars you get. In this way you'll get phrases you'd expect to hear, differences in the play that breaks up that "repeat loop" sound and feel. Now I understand that I can use those guitars and then take the MIDI that is created for the other instruments and assign them to whatever digital instrument I want. I think a wish list is that the RT data is also recorded as "MIDI" or accessible in the same way that other tracks are. After all, if you can see the notes in the window, it would help to have the data, even if the actual RT track can't be manipulated. For example, I could take those notes and double the notes using some other instrument and triggered via MIDI.

RB is a DAW and it's easy to confuse RB with RT and then not be sure what is what. They probably should change the name of RB to something else, IMHO.

I went with the 30 day for the megaultrapak or whatever it is called. I'm using it now and it is darn confusing. I see that I'll need to learn more and figure out how to also make changes I want in certain parts of the song, e.g. where I want a different fill than was provided. I guess the utility of BIAB is that you can just pop in chords and style and generate all those tracks that sound good ASAP. I don't know of any other software that does this well. Hence, this is a useful tool.

As far as Reaper, Cubase, Reason and Presonus come in, I guess I was looking at something that had more to offer than what RB seems to provide. Perhaps its the ancient looking interface that seems awkward to manipulate. In addition, the other DAWs seem to have offered a good amount of additional tools and plugins that would make it worthwhile, although you guys may be right. I'll have to see what works.
