I own a Yamaha CS2x, and decided to utilize the TO HOST port. Connect the cable to the synth, and the other end to your COM1 port.

After this I downloaded from Yamaha's page the CBX driver, which installed very easy. The error you get is unknown to me, since the install package was only one file.

Leave the COM port settings alone, you only have to select in the CONFIG SCREEN at the option MULTIMEDIA or SOUND CONFIG that you wish to use the CBX driver for MIDI.

Don't forget to set this driver in your music programs as well !

Set the switch on the back of the synth to PC-2 or PC-1 and let's play !!
