POSSIBLE CAUSE
¥ Is the amplifier/mixer power turned on?
¥ Is the amplifier/mixer volume set to an appropriate level?
¥ Are the W5/W7 outputs properly connected to the amplifier/mixer inputs?
¥ Are the connection cables shorted, open, or otherwise faulty? Try replacing cables.
¥ Is the W5/W7 connected to a high-sensitivity microphone or instrument input on your
amplifier or mixer? Try turning the W5/W7 output level down to avoid over loading the
amplifier/mixer inputs.
POSSIBLE CAUSE
¥ Is the pan setting on the mixer set to one side and the pan setting of the voice (Voice
Edit Mode) set to the opposite side? (See page 112.)
¥ Is the volume of the selected track set to an appropriate level? (See page 77.)
¥ Are the amp level parameters set high enough? (See page 113.)
¥ Are the voice note and velocity parameters set to appropriate values? (See page 113, 112.)
¥ If a foot volume pedal is connected or a controller is assigned to volume control, is the
controller set to produce a high enough volume level? (See page 147.)
¥ Is the highest note limit or lowest note limit set correctly? (See page 112.)
¥ Is the pitch envelope generator set properly? The pitch may be set below the audible
range. (See page 117.)
¥ Is the filter set in such a way that most of the sound is filtered out? (See page 116.)
¥ Is the total voice level set high enough? (See page 110.)
¥ Is the amplitude envelope generator attack time set to an excessively long value? (See
page 114.)
¥ Is an appropriate wave (element) assigned to the voice? (See page 112.)
¥ Is the velocity curve setting appropriate? (See page 145.)
¥ Are the volume levels of the multi Instruments set high enough? (See page 77.)
¥ Are the sequencer track transmit channels properly matched to the multi Instrument
channels? (See page 82.)
¥ Is the tuning set properly? (See page 78.)
¥ Is the note shift parameter set properly? (See page 78.)
¥ Is the keyboard local off mode selected? (See page 148.)
¥ If the multi used the Song voices before turning the power off, no sound is produced
from the keyboard when turning the power back on, since the Song voice data has been
lost. Change the voice bank or reload the Song voice data.
¥ Are the note shift parameters for each voice set to appropriate values? (See page 118.)
¥ Are the note shift parameters for each multi Instrument set properly? (See page 78.)
¥ Are the tune parameters for each multi Instrument set properly? (See page 78.)
¥ Is the master tune parameter set properly? (See page 78.)
¥ Is the random pitch parameter set properly? (See page 118.)
¥ Is the aftertouch EG bias parameter set properly? (See page 122.)
¥ Is the LFO pitch modulation parameter set to an excessively high value? (See page 121.)
¥ Is the pitch envelope generator set properly? (See page 118.)
¥ Does the sequence data exceed the playback maximum 32-note polyphony of the W5/W7?
¥ Song multi settings including the song name will be retained even when the power is
turned off; however, song sequence data (and Song voice data) will be lost.
