A strange “flanging” or “doubling” sound
occurs when using the PortaTone with a
sequencer. (This may also sound like a “dual”
layered sound of two voices, even when Dual
is turned off.)
• If you are routing the MIDI OUT on the PortaTone to a
sequencer and back to the MIDI IN, you may want to set Local
Control (page 97) to “off” to avoid MIDI “feedback.”
• When using the accompaniment with a sequencer, set MIDI
Echo (or the relevant control) to “off.” (Refer to the owner’s
manual of your particular device and/or software for details.)
The footswitch seems to produce the opposite
effect. For example, when using the footswitch
for sustain, pressing the footswitch cuts off the
sound and releasing it sustains the sounds.
The polarity of the footswitch is reversed. Make sure that the
footswitch plug is properly connected to the FOOT SWITCH jack
before turning on the power.
The AWM tone generation method uses multiple recordings
(samples) of an instrument across the range of the keyboard;
thus, the actual sound of the voice may be slightly different from
note to note.
The sound of the voice changes from note to
note.

DATA BACKUP & INITIALIZATION
Except for the data listed below, all PSR-270 panel settings are reset to their initial settings
whenever the power is turned on. The data listed below are backed up — i.e. retained in
memory — as long as an AC adaptor is connected or a set of batteries is installed.
• User Song Data
• Metronome Volume
• User One Touch Setting Data
• Touch On/Off
• One Touch Setting Bank Number
• Touch Sensitivity
• EZ Chord Data
• Split Point
• EZ Chord Bank Number Data
• Accompaniment Split Point
• Smart Chord Number
• Footswitch Assign Function

VOICE
STYLE
• All one touch setting
(user) and song memory
data, plus the other settings
listed above, will be erased
and/or changed when the
data initialization proce-
dure is carried out.
• Carrying out the data
initialization procedure will
usually restore normal
operation if the PSR-270
freezes or begins to act
erratically for any reason.
Data Initialization
All data can be initialized and restored to the factory preset condition by turning on the
power while holding the highest (rightmost) white key on the keyboard. “CLr Backup” will
appear briefly on the display.
