Troubleshooting

Possible causes
Is the volume sufficiently raised on the QY100
and/or external sound equipment?
Are the headphones or speakers properly con-
nected?
Is the Master Volume and/or each track vol-
umes raised sufficiently?
If the REVERB, CHORUS, VARI, and DRY set-
tings 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?
Is the GAIN control set properly?
Is an appropriate amp simulator setup
selected?
Is the [AMP SIMULATOR] button indicator
out?
If it is, the Amp Simulator is bypassed and
you'll need to press the [AMP SIMULATOR]
button so that its indicator lights.
Does the number of currently sounding notes
exceed the QY100's maximum polyphony of
32?
