Hi Andy,
The best way to connect the SX700 to the PC is via USB-MIDI:
First (!) you connect the SX700's USB-to-Host terminal to a USB socket of the PC (using a USB type "AB" cable and power on the SX700 if you haven't already.
Then (!) install the
Yamaha USB-MIDI Driver V3.1.4 on your PC (for current Windows systems you need the 64-bit version).

https://uk.yamaha.com/en/products/musical_instruments/keyboards/arranger_workstations/psr-sx700/downloads.htmlOn the SX700 go to "Menu > MIDI" and select the preset MIDI template "
KBD & STYLE". This will send the RIGHT keyboard section (to the right of the Left Splitpoint) on MIDI Channel 1 ("Upper"), and the LEFT section will be sent on Channel 2 ("Lower").
In the DAW on the PC, select the "
Digital Workstation" entry of the Yamaha USB MIDI Driver as the
MIDI Input device.
By the way, to control the SX700's
Song parts
from your PC (MIDI Port 1 / Receive), use "
Digital Workstation 1" as the
MIDI Output device in your DAW (recommended). However, to directly control the SX700's
Keyboard parts (MIDI Port 2 / Receive), you use "
Digital Workstation 2" as a
MIDI Output device in the DAW (required less often).
Hope this helps!
Best regards,
Chris
