I purchased the Technics PR 903 last September and like you, very satisfied with the Digital Ensemble. However, I have a passion for collecting extra styles and JazzApprentice if you go to "http://www.ca-software.de"
you will find many free styles for Technics
keyboards including KN6000 which will play
on your PR603 very well.

Incidentally, I have been reading this forum
for a long time, way back to the old forum days. I feel I know many of the regular contributors quite well by now. Thanks
fellas for many enjoyable hours and also
the information so freely given.
