I've heard there is a version 4.0 OS for the Kurzweil PC2, PC2X, and PC2R but cannot find it on the Kurzweil website. Where can I obtain this?
You can either obtain the OS v4.0 from a CDRom included in many of the ROM upgrades or from the Kurzweil FTP site,
ftp.youngchang.com or by following the link at
www.kurzweilmusicsystems.com click downloads, and 'click here to go directly to the FTP site'.
