PRECAUTIONS

PLEASE READ CAREFULLY BEFORE PROCEEDING

* Please keep these precautions in a safe place for future reference.

WARNING

Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from electrical shock,
short-circuiting, damages, fire or other hazards. These precautions include, but are not limited to, the following:

• Do not open the instrument or attempt to disassemble the internal parts or modify
them in any way. The instrument contains no user-serviceable parts. If it should
appear to be malfunctioning, discontinue use immediately and have it inspected by
qualified Yamaha service personnel.

• Do not expose the instrument to rain, use it near water or in damp or wet conditions,
or place containers on it containing liquids which might spill into any openings.

• If the AC adaptor cord or plug becomes frayed or damaged, or if there is a sudden
loss of sound during use of the instrument, or if any unusual smells or smoke
should appear to be caused by it, immediately turn off the power switch, disconnect
the adaptor plug from the outlet, and have the instrument inspected by qualified
Yamaha service personnel.

CAUTION

Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage to the
instrument or other property. These precautions include, but are not limited to, the following:

• Do not place the AC adaptor cord near heat sources such as heaters or radiators,
and do not excessively bend or otherwise damage the cord, place heavy objects on
it, or place it in a position where anyone could walk on, trip over, or roll anything
over it.

• When removing the electric plug from the instrument or an outlet, always hold the
plug itself and not the cord.

• Do not connect the instrument to an electrical outlet using a multiple-connector.
Doing so can result in lower sound quality, or possibly cause overheating in the
outlet.

• Unplug the AC power adaptor when not using the instrument, or during electrical
storms.

• Always make sure all batteries are inserted in conformity with the +/- polarity
markings. Failure to do so might result in overheating, fire, or battery fluid leakage.

• Always replace all batteries at the same time. Do not use new batteries together
with old ones. Also, do not mix battery types, such as alkaline batteries with
manganese batteries, or batteries from different makers, or different types of batteries
from the same maker, since this can cause overheating, fire, or battery fluid leakage.

• Do not dispose of batteries in fire.

• Do not attempt to recharge batteries that are not intended to be charged.

• When the batteries run out, or if the instrument is not to be used for a long time,
remove the batteries from the instrument to prevent possible leakage of the battery
fluid.

• Keep batteries away from children.

• If the batteries do leak, avoid contact with the leaked fluid. If the battery fluid should
come in contact with your eyes, mouth, or skin, wash immediately with water and
consult a doctor. Battery fluid is corrosive and may possibly cause loss of sight or
chemical burns.

• Before connecting the instrument to other electronic components, turn off the power
for all components. Before turning the power on or off for all components, set all
volume levels to minimum. Also, be sure to set the volumes of all components at
their minimum levels and gradually raise the volume controls while playing the
instrument to set the desired listening level.

• Use the specified adaptor (PA-3B, PA-3, PA-4, PA-40 or an equivalent
recommended by Yamaha) only. Using the wrong adaptor can result in damage
to the instrument or overheating.

• Before cleaning the instrument, always remove the electric plug from the outlet.
Never insert or remove an electric plug with wet hands.

• Check the electric plug periodically and remove any dirt or dust which may
have accumulated on it.

• Do not expose the instrument to excessive dust or vibrations, or extreme cold or
heat (such as in direct sunlight, near a heater, or in a car during the day) to prevent
the possibility of panel disfiguration or damage to the internal components.

• Do not use the instrument near other electrical products such as televisions, radios,
or speakers, since this might cause interference which can affect proper operation
of the other products.

• Do not place the instrument in an unstable position where it might accidentally fall
over.

• Before moving the instrument, remove all connected adaptor and other cables.

• When cleaning the instrument, use a soft, dry cloth. Do not use paint thinners,
solvents, cleaning fluids, or chemical-impregnated wiping cloths. Also, do not
place vinyl, plastic or rubber objects on the instrument, since this might discolor
the panel or keyboard.

• Do not rest your weight on, or place heavy objects on the instrument, and do not
use excessive force on the buttons, switches or connectors.

• Use only the stand/rack specified for the instrument. When attaching the stand or
rack, use the provided screws only. Failure to do so could cause damage to the
internal components or result in the instrument falling over.

• Do not operate the instrument for a long period of time at a high or uncomfortable
volume level, since this can cause permanent hearing loss. If you experience any
hearing loss or ringing in the ears, consult a physician.

Yamaha cannot be held responsible for damage caused by improper use or modifications
to the instrument, or data that is lost or destroyed.

Always turn the power off when the instrument is not in use.
Make sure to discard used batteries according to local regulations.

Getting Started

Power Requirements

Although the PSR-74 will run either from an optional AC
adaptor or batteries, Yamaha recommends use of an AC
adaptor whenever possible. An AC adaptor is more
environmentally friendly than batteries and does not
deplete resources.

Using an AC Power Adaptor

To connect your PSR-74 to a wall socket, you will need the
optionally available Yamaha PA-3/3B/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. Connect
one end of the adaptor to the DC IN 10-12V jack on the
rear panel of your PSR-74, and the other end to a suitable
electrical outlet.

DC IN 10-12V

PHONES/
OUTPUT

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.

CAUTION

Never mix old and new batteries or different types of batteries

(e.g., alkaline and manganese).

CAUTION

To prevent possible damage from battery leakage, remove tg£

batteriT from the instrument if it is not to be used for a long time.

● Auto Power OFF

The PSR-74 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.

WARNING

Use ONLY the Yamaha PA-3/3B/4/40 AC Power Adaptor (or other

adaptor specifically recommended by Yamaha) to power your

instrument from the AC mains. The use of other adaptors may

result in irreparable damage to both the adaptor and the PSR-74.

CAUTION

Unplug the AC Power Adaptor when not using the PSR-74, or

during electrical storms.

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 PHONES/OUTPUT jack. Sound from the built-in
speaker system is automatically cut off when you insert a
headphone plug into this jack.

Turning on the Power

Press the STANDBY/ON button 1 to turn on the power of
the PortaTone. Whenever the power is turned on, Voice
01 (PIANO) is automatically selected.

Selecting a Mode

Your PortaTone has three different operating modes:
Voice, Style and Song — each selected from the
corresponding panel buttons. VOICE 2 lets you select
and play a Voice. STYLE 3 lets you select and play a
setting that includes a rhythm/accompaniment pattern.
SONG 4 lets you select and play either a Song or a Jam
Track pattern.

To select one of the modes:

Press the button corresponding to the desired mode. For
now, press SONG 4 to select the Song mode.

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 5 to enter the desired Song or Jam 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.)

beat of every measure, and the right dot flashes at the
other beats. (For more information on the MULTI
DISPLAY, see box at right.)

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 9. 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 simultaneously.
(For more information on the Tempo functions, see
box at right.)

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.

For Songs and Styles in 4/4 time, the dots flash like
this:

For Songs and Styles in 3/4 time, the dots flash like
this:

5. To stop the Song, press the START/STOP button 7

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.

7

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 13.)

Selecting a Voice

1. Press the VOICE button to select the Voice mode.

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, playin 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.

8

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 SYNC-START/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 ACCOMPANIMENT
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.

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
10 and 11 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 7.)

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 ACCOMPANIMENT SECTION.

NOTE

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
ACCOMPANIMENT 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 ACCOMPANIMENT 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.)

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 ACCOMPANIMENT SECTION is set

between the C1 key (the lowest key) and the C2 key.

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.

Fingered Chords

Using the key of C as an example, the chart below shows the types of chords that can be recognized in the Fingered
mode.

NOTE

• If the chord is inverted (i.e., C-E-G is played as G-C-E), the PortaTone will still recognize it as a C chord.

• Minor 6th chords are recognized only in root position, however; all other inversions are interpreted as minor 7th/flatted 5th.

• If augmented and diminished 7th chords are inverted, the lowest note will be recognized as the root.

• 7th flatted 5th chords may be played with the lowest note as the root or the 7th.

• 9th chords are recognized only in root position; all other inversions are interpreted as suspended 4th.

• Augmented 7th and diminished 7th chords are interpreted as simple augmented and diminished.

• The PortaTone also has a Chord Cancel function to stop the chord accompaniment but allow the rhythm pattern to continue playing.

To use Chord Cancel, simultaneously press any three consecutive notes in the AUTO ACCOMPANIMENT SECTION; for example, C, C and D.

One Touch Setting in the Style Mode

The One Touch Setting function automatically selects
an appropriate Voice for playing with the Style you
select. In other words, when One Touch Setting is on,
the Voice automatically changes when you change the
Style.

To turn on the One Touch Setting function, press the
ONE TOUCH SETTING button. (The LED next to the
button lights.)
To turn the function off, press the button again.

NOTE

When the One Touch Setting is on, selecting another Style will

automatically reset the tempo to the default of the selected Style.

11

Song Mode

The Song mode features special Songs and Jam
Track patterns that have been created using the rich
sounds and sophisticated accompaniment functions
of the PortaTone.

The Songs are generally for your listening
enjoyment; however, you can also play along with
them on the keyboard. Also, by using the Minus One
function, you can “mute” the original melody and play
it manually on the keyboard yourself. The Jam Track
patterns in this mode let you “jam” or play along with
a variety of dynamic rhythm styles and chord
changes.

Selecting and Playing a Song
or Jam Track Pattern

1. Press the SONG button to select the Song mode.

2. Use the Numeric Keypad to select the desired Song

or Jam Track number.

If playback is not stopped, all Songs play back
repeatedly in succession, indefinitely. (However, if
Minus One is on, only the selected Song repeatedly
plays back.) If a Jam Track pattern is selected, only
the selected pattern repeats indefinitely.

About the Minus One Function

Minus One, as its name implies, takes away the
melody part of the Song, allowing you to play that part
yourself. You can turn Minus One on before starting a
Song, or do it even while a Song is playing. To help
you play the “missing” melody, scores for all
Songs have been provided; see pages 16-25.

To use the Minus One function with the selected Song,
press the MINUS ONE button (either before starting
the Song or while it is playing). (The LED next to the
button lights.)

One Touch Setting in the Song Mode

The One Touch Setting function works with the Minus
One function and automatically selects an appropriate
Voice for playing the melody along with the Song you
select. Though the Minus One function is not used
with the Jam Track patterns, One Touch Setting works
the same way with Jam Track, automatically selecting
an appropriate Voice.

3. Start the selected Song or Jam Track by pressing the

START/STOP button.

You can also start the selected Song or Jam Track
pattern with the Synchro Start function (as in the Style
mode) by simply pressing any key of the keyboard.

4. If you want to change to another Song or Jam

Track pattern, repeat step 2 above.

5. To stop the Song or pattern, press the START/

STOP button again.

To turn on the One Touch Setting function, press the
ONE TOUCH SETTING button. (The LED next to the
button lights.)

To turn the function off, press the button again.

NOTE

Keep in mind that even with the One Touch Setting function on,

there are some Songs and Jam Track patterns which change the

selected Voice in the middle of the Song or pattern.

Troubleshooting

Problem

When the PortaTone is turned on or off, a buzzing sound
is temporarily produced.

The sound of the voices or rhythms seems unusual or
strange.

Not all notes are heard when playing a number of notes
simultaneously.

The sound of the Voice changes from note to note.

The power cannot be turned on.

Possible Cause and Solution

This is normal and indicates that power is flowing into
the PortaTone.

The battery power is too low. Replace the batteries.

Too many keys are pressed at the same time. The
PortaTone is polyphonic up to a maximum of 12 notes.
(See the note on page 8.)

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.

Quick, successive pressing of the STANDBY/ON button
may fail to turn the power on. When using the
STANDBY/ON button, wait a short time between
successive presses.
