Thanks for your answers and all the helpful advices. It seems indeed not quite easy to get a solo with fits the style and the character of a song. And unfortunately it seems to be impossible at the moment that the solos have something to do with the melody because the musicians, who did the solo, didn't know anything about the melody. But I wonder , if this is definitly impossible . Perhaps there could be a kind of inbuild AI in Biab, which analyzes the melody ( like the chords were analyzed) and this knowledge has an influence on the solo. Sorry, just a dream of mine. 🤔
