Yamaha 9000Pro Owner's Manual - Page 188

Troubleshooting PROBLEM • When using a mobile phone, noise is produced. • No sound results. • Not all simultaneously-played notes sound. • Auto Accompaniment seems to "skip" when the keyboard is played. • The accompaniment or song does not play back even when pressing the [START/STOP] button. • The Multi Pads do not play back, even when one of the MULTI PAD buttons is pressed. • The auto accompaniment does not start, even when Synchro Start is in standby condition and a key is pressed. • Certain notes sound at the wrong pitch. • Auto accompaniment chords are recognized regardless of the split point or where chords are played on the keyboard. • The Harmony function does not operate. POSSIBLE CAUSE/SOLUTION Using a mobile phone in close proximity to the 9000Pro may produce interference. To prevent this, turn off the mobile phone or use it further away from the 9000Pro. • The R1/R2/R3/L voice volume (Main Mixer) settings could be set too low. Make sure the voice volumes are set at appropriate levels (page 25). • The Local Control function could be turned off. Make sure Local Control is turned on (page 175). • The [MASTER VOLUME] controls or foot volume are turned all the way down. Set the [MASTER VOLUME] controls and foot volume to a reasonable listening level. • Are the desired parts turned on? ([PART ON/OFF] button - page 57) • A pair of headphones is plugged into the PHONES jack. Unplug the headphones. • A plug is inserted in the LOOP SEND jacks. Unplug the LOOP SEND jacks. • Is the Footswitch connected to the FOOT VOLUME connector? • The [FADE IN/OUT] button is on and has reached the end of its duration, muting the sound. Press the [FADE IN/OUT] button so that its indicator goes out. • Check whether the external speaker is connected properly. You are probably exceeding the maximum polyphony of the 9000Pro. The 9000Pro can play up to 126 notes at the same time - including voice R2, voice R3, voice L, auto accompaniment, song, and multi pad notes. When the maximum polyphony is exceeded, the earliest played notes will stop sounding, letting the latest played notes sound. This is referred to as "lastnote priority." The MIDI Clock may be set to "EXTERNAL." Make sure it is set to "INTERNAL" (page 175). You may be trying to start accompaniment by playing a key in the righthand range of the keyboard. To start the accompaniment with Synchro Start, make sure to play a key in the left-hand (accompaniment) range of the keyboard. Make sure that the scale tuning value for those notes is set to "0" (page 158). Check whether the fingering mode is set to "Full Keyboard" or not. If the Full Keyboard fingering mode is selected, chords are recognized over the entire range of the keyboard, irrespective of the split point setting. • Harmony cannot be turned on when the Full Keyboard fingering mode is selected. Select an appropriate fingering mode. 188 Reference 186
