GOOD NEWS!
I just received in the mail today, the latest version (version 1.6 (v.2.64) of the arranger keyboard Style Converter software program "EMC Styleworks Universal" and was elated to find that the program now (finally) includes support for General Music models: WK2, WK3, WK4, WK6, and WK8 keyboards. The one dissapointing piece of news is that the Technics KN6000 is not currently supported. I assume that the KN6000, Roland VA7 and Korg PA80 will be added in the future.
