Thanks for leading me in the right direction, fellas.
Al, cleaning up the UI - I will try to do so. Still, the design looks cheapo and unfriendly to my eyes.
Bluesplayer, thanks for pointing out that BIAB and yamaha use different stylestructures even if the ending sounds the same. I am quite unhappy about this bcause I feel that BIAB styles sound a little simple to me. I hoped to use yammie dance and R&B styles to make up for that, but tweaking those styles seems quite timeconsuming then.
I did not understand though what you meant by subvariations - can they be compared to varaitions C, D and Breaks of the real keyboards qualitywise?
Has anybody here trie to combine steinbergs groove agent or virtual bassist with OMB or BIAB?
Or does Jammer pro a better job than BIAB for contemporary music? I understand it takes a lot of work to set up songs with it...
Sorry for so many questions, I am still at the beginning of the software route. Might be I am leaving it as stam pointed out.

Best regards

Heinrich
