I do use Jammer for creating drum and sometimes bass parts, but for style conversion korg provides a freeware tool that works well once you get used to using it. I sequence in XG works and cakewalk. I use XG works to asist in style to,style conversion because it plays all of the Yamaha styles ( and any style converted to Yamaha format ) from within by writing the pattern and chord in step time to a midifile. I can also use it along with the korg software to quickly accomplish Yamaha .sty to korg .sty style conversions. I am going to give EMC styleworks a tryout as well, but I'm not sure whether that will or won't make the process any easier ior faster.

The real challenge is in tweaking the styles so that they sound good once you get them on the PA80, but with all of the functions included in the Korg style sequencer, it is very doable. It probably takes me anywhere from about 10 mins to over 30 mins from start to finish to convert a style, and maybe a little longer to make a new one from existing parts of different styles ( that aren't on the PA80 already ) or from scratch, depending on what is involved with that particular style. That includes setting up 4 different voices for the STS settings ( single touch settings or in Yamaha speak One touch settings ). The Pa80 also has the style mix and match function so that any part(s) of an existing PA80 style can be mixed easily and quickly with another or several others. This includes taking one or more instrument parts from a single variation or all of the variations in a style if desired and mixing it with others.
