When you decide to buy Band In A Box.... buy as far up the version chain as you can buy. Ultra plus pack as a minimum or the Everything Pack..... Stop short of the Audiophile version. You really don't need that version unless you absolutely have the money and want it. The Everything pack is exactly what it says.... it's everything. Could be considered a bit pricy BUT..... pay for a good session with some Nashville pickers and you could have bought the Everything pack and had those guys on call for all your music. Real tracks are recordings of the best of the best studio and working musicians recorded in such a way that the program takes those recordings and somehow.... don't ask me how it does it, shapes that playing into the song YOU are asking it to play..... in the key you chose, at the tempo you selected, and in the style you like.
The further up you go, the more stuff you get and that includes ALL of the real tracks. I use Real Tracks and the Real Drum Tracks exclusively in my musical compositions. 100% audio files. The real tracks are simply amazing. Compose it in Band in a Box and then render the real tracks in Real Band. RB is a DAW of sorts but I never use it for that. I simply use it to generate the real track waves. When done right, the result is breathtaking.
If you have not done so..... go to my music site below and listen to some of the songs on the first page. Everything there is either 100% BB/RB with the Real Tracks or a combination of RT's and my live guitar playing combined. I mix, produce, edit, and export the finals from SONAR. Look for a song called The Best Christmas..... this one is a great example of Real Tracks playing a hot country solo. Nothing in that song was played live. It's 100% BB/RB.
They are starting to add dance music and electronic genres and styles to the RT's so there may be some things in there to get you going in that style/genre. Euro-tech, Enya, etc....
