Congratulations on your purchase of the Yamaha PortaTone
You now own a portable keyboard that packs advanced functions and great sound in a highly compact
size. Its outstanding features also make it an exceptionally expressive and versatile instrument.
Read this Owner’s Manual carefully while playing your new PortaTone in order to take full advantage of its
various features.
Main Features
The PortaTone is a sophisticated musical instrument with the following features and functions:
● Exceptionally realistic sounds with 100 AWM (Advanced Wave Memory) Voices, utilizing digital recordings
of actual instruments.
● Dynamic, versatile rhythms and accompaniment with 100 music Styles.
● 20 Songs, for listening enjoyment or for playing along with when using the Minus One function.
● 20 Jam Track patterns, providing specially programmed rhythms and chord progressions for playing along
with.
● One Touch Setting, for automatically calling up an appropriate Voice for playing with the Style, Song or Jam
Track you select.
● High-quality amplifier/speaker system.
Precautions — Taking Care of Your PortaTone
Your new PortaTone is a fine musical instrument — and should be treated as such. Handle it with care and
common sense, and it will give you years of enjoyment.
Location
● Avoid exposure to direct sunlight or other sources
of heat. Never leave it inside a car where it can get
very hot. Also avoid highly humid or dusty places.
Interference From Electromagnetic Fields
● Do not use your PortaTone close to television sets,
radios or similar equipment since this may cause
interference noise in the other appliance.
Handling
● Protect your PortaTone from strong impact. Be
careful not to drop it or place heavy objects on it.
Avoid applying excessive force to the controls and
keys.
Cleaning
● Clean the exterior with a soft, dry cloth. To
remove stubborn stains, use a slightly moistened
cloth.
● Never use alcohol, thinner, or other chemical
solvents, since they will damage the finish. Also,
do not leave vinyl chloride material on the PortaTone
for a long time, since it may adhere to the exterior.
NOTE
Yamaha is not responsible for damage caused by improper
usage.
When Not Using the Porta T one
● After use, always turn off the POWER switch. When
not using your PortaTone for long periods, be sure
to remove the batteries to avoid damage through
battery leakage.

Getting Started
Power Requirements
Your PortaTone can run either on batteries (sold separately) or on normal household current by using the
optional Yamaha PA-3/4/40 Power Adaptor.
Using an AC Power Adaptor
To connect your PortaTone to a wall socket, you will
need the optionally available Yamaha PA-3/4/40 Power
Adaptor. Use of other AC adaptors could result in
damage to the instrument, so be sure to ask for the
right kind. Plug the adaptor into a convenient wall
outlet and its connector into the DC 10-12V IN jack on
the back of your PortaTone.
Using Batteries
Inserting Batteries
Turn the instrument upside-down and remove the
battery compartment lid. Insert six 1.5-volt size “D”
batteries as shown in the illustration, making sure that
the positive and negative terminals are properly aligned.
Replace the lid.
Accessory Jacks
Using Headphones
For private practicing and playing without disturbing
others, connect a set of stereo headphones to the rear
panel HEADPHONES/AUX OUT jack. Sound from the
built-in speaker system is automatically cut off when
you insert a headphone plug into this jack.
HEADPHONES/
AUX OUT
Connecting a Keyboard Amplifier
or Stereo System
After making sure the PortaTone and any external
devices are turned off, connect one end of a stereo
audio cable to the LINE IN or AUX. IN jack(s) of the other
device and the other end to the HEADPHONES/AUX OUT
jack of the PortaTone.
DC IN 10-12V
When the Batteries Run Down
When the batteries run low and the battery voltage
drops below a certain level, the PortaTone may not
sound or function properly. As soon as this happens,
replace them with a complete set of six new batteries.
Never mix old and new or different types of batteries
(e.g., alkaline and manganese).
Auto Power OFF
The PSR-73 features an Auto Power OFF function that
automatically turns the power OFF if the instrument is
not used for approximately 30 minutes. This functions
whether batteries or the AC power adaptor is used.
The Music Stand
Insert the bottom edge of the music stand into the slot
located at the top rear of the PSR-73 control panel.

Playing a Song
in the Song Mode
A variety of Songs and special Jam Tracks have been
recorded to your PortaTone to give you a taste of what
you can do with the instrument, and to provide music
and patterns for you to play along with.
To select and play one of the Songs:
1. With the Song mode selected, use the Numeric
Keypad
Track number. Be sure to enter a two-digit
number, as is printed next to each song on the
panel. For example, to select Song 09, first
press “0” on the Numeric Keypad, then “9.”
You can also use the +/– buttons on the Numeric
Keypad to step up or down through the preset
numbers; holding down the appropriate button
continuously changes the number. Note that the
+/– buttons have a “wrap around” feature. For
example, pressing the + button from the last
number returns to Song 01. (Song 01 is also
automatically selected when you turn the power
on.)

About the MULTI DISPLAY
As mentioned above, the dots in the MULTI DISPLAY
flash in time with the rhythm, and the indication is
used when a Song or Style plays back. This flashing
provides a visual indication of both the tempo and
the time signature of the rhythm.
3.Adjust the volume of the Song by using the
VOLUME control
.
4.Although the Song is automatically set to play at a
default tempo, you can change the speed of the
Song by using the TEMPO buttons
. Press TEMPO
+ to increase the speed and TEMPO – to decrease it;
holding down the appropriate button continuously
increases/decreases the speed. (Note that the
tempo value is briefly shown in the MULTI DISPLAY.)
If you want to set the tempo back to its original
default setting, press both TEMPO buttons simulta-
neously. (For more information on the Tempo
functions, see box at right.)
5.To stop the Song, press the START/STOP button
again.
NOTE
You should enter numbers on the Numeric Keypad relatively
quickly. If you do not enter the second digit of a number
within about ten seconds after entering the first digit, the first
digit will be cancelled. Entry of a first digit is also automatically
cancelled if any other button on the panel (except for those
on the Numeric Keypad) is pressed before entering the second
digit. Also, keep in mind that entry of numbers higher than 40
in the Song mode are ignored.

About the Tempo Functions
Tempo Values
As mentioned above, the tempo value is shown
briefly in the MULTI DISPLAY when one of the TEMPO
buttons is pressed. The displayed tempo range is
from 10 to 60; in actual tempo values, the range is
from 40 to 240 beats per minute. (Each step in the
tempo adjustment corresponds to 4 beats per
minute.)
Default Tempos
Each Song and Style has been given a default or
standard tempo. If you change the tempo, you can
set it back to the original default setting, by pressing
both TEMPO buttons simultaneously. Also, the
tempo of a Song or Style returns to the default
setting when selecting a different Song or Style. (The
set tempo remains, however, when switching Styles
during playback.) When you turn on the power of
the PortaTone, the tempo is automatically set to the
default setting of Style 01.

Voice Mode
The Voice mode features 100 authentic Voices.
Many of these Voices have special preset characteristics or embellishments. The Voices are divided
into various categories depending on their characteristics or the effects used.
Dual Voices (#41 - #56) feature two Voices mixed
together in a layer for rich ensemble sounds. Split
Voices (#57 - #67) also have two Voices, but rather
than being layered, each is played from a different
range of the keyboard. Sustain Voices (#68 - #72)
extend the sound by adding a natural, slow release. Harmony Voices (#73 - #85) have an additional one-, two- or three-note harmony added to
the original monophonic Voice. Finally, Echo
Voices (#86 - #00) have an echo effect that adds
delayed repeats to the original Voice.
Included in the Voices are special PERCUSSION
Voices (#40 and #00) that lets you play various
drum and percussion sounds from the keyboard.
(Refer to the Percussion Assign List page 10.)
Selecting a Voice
1. Press the VOICE button to select the Voice mode.
VOICE
About the Harmony Voices
Since Harmony Voices are designed to automatically
play two or more notes with the notes you play on
the keyboard, only one note can be played on the
keyboard at a time. If several notes are played
together, only the last note or highest note played
will be heard.
The type of harmony used depends on the Voice
that is selected. When a Style or Song/Jam Track is
not being played back, the basic key for the harmony
is always C. When a Style is played or the Stopped
Accompaniment function is active, the harmony
changes according to the chord played with the left
hand. When a Song is played back, the harmony
changes according to the chord progression of the
Song or Jam Track.
NOTE
The PortaTone is polyphonic up to a maximum of 12 notes.
(Depending on the Voice selected, fewer notes may be
available.) This includes not only the Voices played from the
keyboard, but also the notes in a Style pattern, and so on.
Thus, if you play too many notes at one time, some may not
sound and/or others may be cancelled.
2.Use the Numeric Keypad to select the desired
Voice number.
Each Voice is automatically called up with the
most suitable octave range setting. Thus, playing
middle C with one Voice may sound higher or
lower than another Voice at the same key.

3.Play the newly selected Voice. To change to
another Voice, repeat step 2 above.
You can also play rhythm Styles in the Voice mode
by simply pressing the START/STOP button. The
Style last selected from the Style mode will be
played.

Style Mode
The Style mode provides dynamic rhythm/
accompaniment patterns — as well as Voice settings appropriate for each pattern — for various
popular music styles, as listed on the panel. A total
of 100 different Styles are available, and are
divided into ten different categories. Each rhythm
pattern also has a specially created companion Fill In
pattern, which can be played by using the SYNCSTART/FILL IN button.
Auto Accompaniment features built into the
rhythms add the excitement of instrumental
backing to your performance, letting you control
the accompaniment by the chords you play. Auto
Accompaniment effectively splits the keyboard
into two sections: The upper is used for playing a
melody line, and the lower (labeled “AUTO ACCOMP.
SECTION” on the keyboard, including keys C1
through F2) is for the Auto Accompaniment
function.
Selecting a Style
1. Press the STYLE button to select the Style mode.
STYLE
4. With the rhythm running, you’re ready to try out
the Auto Accompaniment feature. Try playing a
few single notes with your left hand, and notice
how the bass and chord accompaniment change
with each key you play. (Refer to the boxed
sections on pages 7 and 8 for more information on
how to use Auto Accompaniment.)
5.Use the TEMPO buttons to change the tempo of the
Style as it’s playing. (For more information on
the Tempo functions, see page 4.)
6.While the Style is playing, you can add variation
to the rhythm by playing special Fill In patterns.
To play a Fill In pattern, press the SYNC-START/
FILL IN button.
NOTE
The Fill In pattern may not play precisely when you press the
SYNC-START/FILL IN button, but instead starts on the beat
immediately following your press of the button. Also, depending on when you press the button, only a portion of the
Fill In might be played. Both of these situations are normal
and are done to ensure that the Fill In pattern complements
the basic rhythm, rather than disrupting it.
2.Use the Numeric Keypad to select the desired
Style number.

3.You can start the selected rhythm by pressing the
START/STOP button.
The PortaTone also has a Synchro Start function
that allows you to start the rhythm by simply
pressing a key on the keyboard. To use Synchro
Start, first press the SYNC-START/FILL IN
button, then press one of the keys in the AUTO
NOTE
ACCOMP. SECTION.
Synchro Start is automatically set to stand-by when you select
the Style mode. (The dots in the MULTI DISPLAY flash to
indicate stand-by status.)
7.To stop the rhythm, press the START/STOP
button again.
Pressing the START/STOP button while the
rhythm is playing produces a simple ending
phrase. This also applies to playing Jam Track
patterns in the Song mode.

Using the Auto Accompaniment Function/Multi Fingering
The Auto Accompaniment function automatically generates bass and chord accompaniment for you to play along
with, by using Multi Fingering operation. You can change
the chords of the accompaniment by playing keys in the
AUTO ACCOMP. SECTION of the keyboard using either the
“Single Finger” or “Fingered” method. With Single Finger
you can simply play a one-, two- or three-finger chord
indication (see Single Finger Chords below). The Fingered
technique is that of conventionally playing all the notes of
the chord. Whichever method you use, the PortaTone
“understands” what chord you indicate and then automatically generates the accompaniment.
NOTE
Chords played in the AUTO ACCOMP. SECTION of the keyboard
are also detected and played when the accompaniment is
stopped (Stopped Accompaniment function). In this
condition, the Voices used for the bass and chords are
automatically selected.
Single Finger Chords
Chords that can be produced in Single Finger operation are major, minor, seventh and minor seventh.
The illustration below shows how to produce the
four chord types. (The key of C is used here as an
example; other keys follow the same rules. For
example, B
♭
7 is played as B♭ and A.)
C
Press the root note of the chord.
C7
Press the root note together with
any white key to the left of it.
Cm
NOTE
To use the Minus One function with one of the Styles, press
the MINUS ONE button. (The LED next to the button lights.)
Minus One cancels all chord accompaniment, leaving only the
bass and basic rhythm of the Style.
Setting Auto Accompaniment to Single
Finger or Fingered
Though detection of the Single Finger and Fingered
methods is automatic, you can set Auto Accompaniment to function exclusively in either the Single
Finger or Fingered mode.
To set Auto Accompaniment to Single Finger, turn
the power off, then hold down the “–” button on the
Numeric Keypad and simultaneously turn the power
on. “SF” (Single Finger) briefly appears in the MULTI
DISPLAY.
NOTE
In Single Finger, the AUTO ACCOMP. SECTION is set between
the C1 key (the lowest key) and the C♯2 key.
Press the root note together with
any black key to the left of it.
Cm7
Press the root note together with
any white and black key to the
left of it (three keys altogether).
To set Auto Accompaniment to Fingered, follow the
same steps, holding down the “+” button instead.
“F” (Fingered) briefly appears in the MULTI DISPLAY.
To switch back to Multi Fingering operation, simply
turn the power off and on again.
