Hi,
another option for kn owners that don't own psr's but do own pc's would be software called One Man Band (or Busker would probably even work.)
Both of these programs load PSR styles.
Simple case of doing a drop n drag of the psr style parts , intro's endings etc
( works a bit like Band in a Box ) Type in your C Chord. Save as midifile.
Then continue on as Frank explained.
You do get the occasional incorrect drum playing because PSR is drum mapped to xg wheras Technics isn't, just need to be edited in the composer.

There is also the option of just changing psr ".sty" extension to " . mid" you end up with a midifile of the style, problem is psr styles are based on a maj7th chord not neccesarily a cmaj7 either. Could be a bit fiddly editing it to get a good midifile .

best wishes
Rikki
