Troubleshooting
If you encounter problems such as no sound output or abnormal behavior, verify the connections before
checking the following.

Sound does not change when using the knobs or sliders.

• Is “ONLINE” indicated on the Editor window?
• Is the lamp at left of “ONLINE” indicator turned on?
If it is turned off, the settings related to communication between the S90 XS/S70 XS and a
computer may be wrong. Check the MIDI Port setting on the S90 XS/S70 XS Editor and Studio
Manager, the MIDI IN/OUT parameter setting in the MIDI display of the Utility mode on the S90
XS/S70 XS instrument, or the cable connection between the S90 XS/S70 XS and the computer.
• Check the MIDI Port setting and Device No. setting. (page 39)

Bulk data is not transmitted/received successfully.

• Check the same points as above such as “ONLINE” indication and MIDI Port settings.

The appropriate Port is not shown in the Setup window.

• The MIDI Port in the Setup window can be selected from the Ports specified in the host
application. Check the MIDI Port settings in the host application.
• When “!” is shown at left of the Port name (e.g., “! Yamaha USB IN 0-1”), this indicates that the
previously used Port cannot be found or some Ports are not set properly. Check the MIDI Port
settings in the host application.
