As far as making modern sounding music with BIAB I believe that it will be possible when I purchase the full version. I may have to add in some MIDI and VST instruments to get the drums and synths needed to make a modern pop hit but I believe that all the basics needed can be found here in BIAB. I look forward to challenging myself to use the program to it's fullest extent and seeing what I can come up with.
Exactly, if you just spend some time in the styles section and look at the techno, eletronica, and dubstep sections you can find 80% of this in sample loops that will play themselves.
Then go find a mandolin and the right acoustic.
Next find a Real drum track and layer it in, and use a lot of EQ and reverb so it will thump.
Lastly, fill in missing percussion or synth parts with Sample Tank 3 or something similar. Done.
20 minutes.
It's not that hard.
