Possible Cause and Solution
This is normal and indicates that the PortaTone is receiving electrical
power.
The battery power is too low. Replace all batteries with new ones of
the same type. (See page 3.)
Too many keys are pressed at the same time. The PortaTone is
polyphonic up to a maximum of 28 notes. (See page 42.)
The Local Control setting could be off. Make sure Local Control is
turned on. (See page 40.)
Make sure that you’re playing in the Auto Accompaniment section of
the keyboard. (See page 22.)
Also, make sure that you’re using the proper Fingering mode and that
you’re playing “legal” chords that the PortaTone can recognize. For
example, when playing Single Finger chords, make sure that the Single
Finger mode is selected. (See page 26.)
Check that nothing is connected to the PHONES/AUX OUT jack on the
rear panel. When a set of headphones is plugged into this jack, no
sound is output.
Make sure that the following settings are appropriate: Main Voice
Volume (page 11), Dual Voice Volume (page 13), and Split Voice
Volume (page 15)
Make sure that the Accompaniment Volume or Song Volume is set to
an appropriate level. (See pages 23, 32.)
Split Point 2 (page 15) cannot be set lower than the Accompaniment
Split Point (page 26). Also, the Accompaniment Split Point cannot be
set higher than Split Point 2.
Connecting the footswitch after power is on reverses the footswitch
operation (polarity). For normal operation, turn off the power,
connect the footswitch, then turn the power back on (without pressing
the footswitch).
Make sure that an appropriate Yamaha Music Cartridge is properly
inserted into the Cartridge slot. Also, make sure that the electrical
contacts on the Cartridge are clean and free from foreign particles.
Insert and remove the Cartridge several times, and try the operation
again. If the problem persists, clean the contacts with a soft, dry cloth.
Make sure that the Harmony Volume is set to an appropriate level.
(See page 17.)
Harmony/Echo is not available when the Full Fingering mode (page
26) is on, and will automatically be turned off when the Full Fingering
mode is selected.
Whenever using a MIDI device to control the PortaTone, make sure
that the Receive Switch is set to “on” for the appropriate channel or
channels. (See page 40.)
When the Song or Easy Chord Memory mode is selected, MIDI data
cannot be transmitted or received, and none of the MIDI menu settings
have any effect. Select another mode (Voice or Style).
While a Song or Rhythm/Accompaniment are being played back, the
mode cannot be changed. Stop the Song or Rhythm/Accompanyment
and press the VOICE, STYLE, SONG, or EASY CHORD MEMORY
(REC/END) button.
