Vquestor, thanks for kind comments.
At the moment I still use Live - Styler as my first choice. It has an excellent user interface. You can tailor it to suit your needs, e.g., performance setups for styles and voices, etc. In addition, if I get a touch screen in future it is well suited for that approach (Refer Branda in Germany
www.branda.de ). OMB has its pluses too. It plays the PSR2000, Tyros, etc. styles better, i.e., without modification for such things as OTS.
Finally, you might be right that I missed an opportunity with M-Audio and RT Player Pro. Oh well!!!
