Does anybody know where I could find (download) drivers for connect my PSR-630 with HOST-cable to PC (serial port)

Please let me know!!!

Hello........Go to the Yamaha link below and click on PSR630 under the older PSR keyboards section. On the next page you will find the link for the reqired CBX driver. Instructions come with the download. Good luck.
