Troubleshooting

If you experience problems such as “no sound,” “incorrect sound,” or “sequencer

does not operate,” please check the following points before deciding that the unit is

malfunctioning. In many cases, checking these points will help you solve the problem.

If this does not solve the problem, contact your nearest Yamaha dealer or the autho-

rized distributor for your country.

Problem

No sound

Possible causes

Is the volume sufficiently raised on the QY70

and/or external sound equipment?

Are the headphones or speakers properly

connected?

Is the Master Volume and/or each track

volumes raised sufficiently?

If the REVERB, CHORUS, VARI, and DRY

settings are all set to 0, the sound for that

track will not be produced.

Is the Fingered Chord function turned ON? If

you play a note within the Fingered Zone, no

sound will be produced.

Is the MUTE setting turned ON?

Is the MIDI IN jack or TO HOST jack properly

connected?

Is the HOST SELECT switch properly set?

Is MIDI local set to OFF?

Have unneeded effects been set?

Does the number of currently sounding notes

exceed the QY70’s maximum polyphony of

32?

Does the selected song/pattern contain data?

Is the MIDI Sync set to external?

Is Style Number 129 (End Pattern) selected in

the Song Mode’s display?

The length of a pattern (number of measures)

cannot be changed, if it includes recorded

user phrases.

Refer to page
