After reading Mac's reply, I thought I'd give it a try around guitar solos.

This is just for fun. Just an example.

How I did this one.

Let the melodist create a song, I picked "No Form" as this is just an example. The "style" doesn't matter as you'll replace tracks with realstyles - well the midi from realstyles.

Add a realtrack guitar Solo, like a Brent Mason Ballad guitar solo.
1168:Guitar, Electric, Soloist RockBalladBrent Ev 065 (Bluesy)

These kind of tracks have midi. Then Edit -> Copy Track to another track.

I did this twice. Then I added VSTi instruments to those tracks that sounded ethnic to me. One said "Koto", the other some flute thing.

I slowed the tempo down to 30. This is as slow as I could get. Therefore why it ended up being so long.

It sounds interesting. smile

To fill in I added strings and bambo sticks.

The strings are the High-Q Sampletank ones that come with BIAB.

You can create a wave file with the same name as the Song and BIAB will play it. I added some ambient windy chime thing. And put this on the same track as the piano.

There is some distortion so in real life check the levels.
Have fun - this is all fun!
