Hi,
I have created the odd biab based style for my korg pa_x's.
You possibly will find a couple of problems creating them for yamaha arrangers. BIAB styles use the Sustain controller , Yamaha styles don't. So piano tracks for instance , will sound choppy. One way around it would be to lengthen notes. Extra work.
Also I found another problem, even if you put in a chord CMaj 7, which works for both yamaha and korg styles, biab tends to add notes that aren't part of the cmaj7th chord, it's possibly adding extensions?, but it makes it tricky to create settings. Also it might limit the style phrases biab picks. Even if one uses Cmaj chord, it sometimes adds extra notes
I ended up editing BIAB styles and removing or muting style parts that probably wouldn't work.
Just an ongoing project I go back to once in a while.
Currently using it to create the odd intro/ending.
Haven’t tried it with midi to style, maybe you might have a bit more luck.
Currently having problems accessing this site with my iPad, so may not be able to get back in.
