AT first listen that may be so BUT with a little work and lateral thinking you can write some amazing songs, in any style. Just do not expect to press a button and get a song styled like Radiohead, Lady Gaga or whoever. However I do not use RealTracks I use MIDI and MIDI means to me that anything is possible with a bit of editing, sometimes a lot of editing It just takes time to get what my ears want.

To me BIAB is what it says on the box, it is the best band a man/woman can ever have in his/her home studio and I say that without ANY reservation. After initially writing on guitar/piano all my songs are then developed in BIAB, with a bit of adjusting in another program J**mer, and finished in Cubase SX, or ACID, with a few VSTi's such as FL Studio.
Having just said this in defence of BIAB, which I have used for maybe 20 years, I now will have to put some of my songs on line as examples.

Some really great songs are already on line in the User Showcase, produced with Real Tracks/Instruments, but I won't name names in case I forget some. Take a listen.
