Thanks. Much appreciated. By "wave" you mean from the audiofile upgrade?
I was hoping not to have to learn a new DAW.
What's the downside to doing it all in Real Band.
No, not the audiophile .... your normal BB will export the files in WAV format.
Real Band is a DAW and you are free to use it in that manner. It can generate more tracks than BB will do, and tracks outside of the style you selected in BB. For example, if you want to use LA Hard Rock style, you get guitars, bass, and drums. But in RB you can add things like fiddle, steel, etc to the style. I have a number of songs where that exact thing was done.
Doing it on the computer..... yeah, you might not be a techie but there is a certain amount of knowing the computer and how to work with it that is required to get to the "pro" levels with your music.
