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. 4  Getting Started Power Requirements ● 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. 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. CAUTION Never mix old and new batteries or different types of batteries Using an AC Power Adaptor (e.g., alkaline and manganese). 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. 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. DC IN 10-12V PHONES/ OUTPUT DC IN 10-12V 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. 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 PHONES/ OUTPUT DC IN 10-12V 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. Connecting a Keyboard Amplifier or Stereo System Using Batteries ● Inserting Batteries 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 PHONES/OUTPUT jack of the PortaTone. 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.

Whenever the power is turned on, Voice 01 (PIANO) is automatically selected. 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. 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 and play one of the Songs: 1. To select one of the modes: 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 Press the button corresponding to the desired mode. For now, press SONG 4 to select the Song mode. +/– 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.) 6  2. To play the selected Song, press the START/STOP button 7. About the MULTI DISPLAY Note that the dots in the MULTI DISPLAY ! flash in time with the music. The left dot flashes at the first beat of every measure, and the right dot flashes at the other beats. (For more information on the MULTI DISPLAY, see box at right.) 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: 3. Adjust the volume of the Song by using the VOLUME control @. 1st beat 2nd beat 3rd beat 4th beat MULTI DISPLAY MULTI DISPLAY MULTI DISPLAY MULTI DISPLAY 4. Although the Song is automatically set to play at a BEAT 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.) BEAT BEAT BEAT For Songs and Styles in 3/4 time, the dots flash like this: If you want to set the tempo back to its original default setting, press both TEMPO buttons simultaneously.

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.) 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 Default Tempos cancelled. Entry of a first digit is also automatically cancelled if 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. 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. 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.) 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 Selecting a Voice 1. The PortaTone is polyphonic up to a maximum of 12 notes. (Depending on the Voice selected, fewer notes may be available.) Press the VOICE button to select the Voice mode. 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 4. With the rhythm running, you’re ready to try out the 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. 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 Selecting a Style 1. The Fill In pattern may not play precisely when you press the SYNC-START/FILL IN button, but instead starts on the beat Press the STYLE button to select the Style mode. 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. 7. To stop the rhythm, press the START/STOP button 2. Use the Numeric Keypad to select the desired Style again. number. 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. 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.) 9  Using the Auto Accompaniment Function/Multi Fingering 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.) 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. C Press the root note of the chord. C7 NOTE Chords played in the AUTO ACCOMPANIMENT SECTION of the Press the root note together with any white key to the left of it. keyboard are also detected and played when the accompaniment is stopped (Stopped Accompaniment function). In this condition, Cm the Voices used for the bass and chords are automatically selected. NOTE Press the root note together with any black key to the left of it. 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 Cm7 cancels all chord accompaniment, leaving only the bass and basic rhythm of the Style. Setting Auto Accompaniment to Single Finger or Fingered Press the root note together with any white and black key to the left of it (three keys altogether). 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. 10  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. Fingered Chords in the Key of C C C7sus4 Cm Caug(7) C7 Cdim(7) Cm7 C7
5 CM7 CmM7 Cm7
5 Cm6 Csus4 C9 Notes enclosed in parentheses are optional; the chords will be recognized without them. 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 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. 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. 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. Selecting and Playing a Song or Jam Track Pattern 1. 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.) Press the SONG button to select the Song mode. 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. 2. Use the Numeric Keypad to select the desired Song or Jam Track number. To turn on the One Touch Setting function, press the ONE TOUCH SETTING button. (The LED next to the button lights.) 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. To turn the function off, press the button again. 4. If you want to change to another Song or Jam NOTE Track pattern, repeat step 2 above. Keep in mind that even with the One Touch Setting function on, there are some Songs and Jam Track patterns which change the 5. To stop the Song or pattern, press the START/ selected Voice in the middle of the Song or pattern. STOP button again. 12  Troubleshooting Problem Possible Cause and Solution When the PortaTone is turned on or off, a buzzing sound is temporarily produced. This is normal and indicates that power is flowing into the PortaTone. The sound of the voices or rhythms seems unusual or strange. The battery power is too low. Replace the batteries. Not all notes are heard when playing a number of notes simultaneously. 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 sound of the Voice changes from note to note. 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 power cannot be turned on. 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. s as as B B s D ru Sn D m 1 ar ru Sn e D m 2 ar ru e m D 2 To rum m 3 To Bas m s To Low m Sp To M id m l Sy as nt h Hig Sy h Cy h nt Ba mb h ss a Sy Sn Dr l nt are um h Sy To Dru nt m m h Sy To Bas nt m s Sp Syn h T Lo la th om w sh T M C om id ym H ba ig lM h ut e Sn ar e D R im rum Sh 1 ot H i-h a H t Pe i-h da a l H tC i-h lo s at e O pe C n ra sh C Sy ym nt b h R al im C Sh ra sh ot Sy C nt ym b h Sy Hi al nt -ha Mu h t H tC e i-h lo at se O pe n Percussion Assign List (Voices 40 and 00) 13  Jam Track Chord Progression List 21 DANCE Am7 Em7 C7 Dm7 Am7 F7 =116 22 RAP Dm7 Am7 =92 F7 C7 =104 C7 A7 Dm7 G7 =192 C7 G 7 G7 Am G7 C7 Dm7 =128 33 FUSION G7 Gaug Dm7 =144 25 MINOR BLUES Em7 Dm Am E Am E 7 =120 =112 =124 E7 =136 Am 37 SKA C =160 Am C G =144 28 ROCK'N'ROLL F F7 Am7 C C F C C =88 F F G7 G7 C =116 G7 C =84 40 NEW AGE C7 30 SLOW ROCK C C =136 G7 =120 39 MARCH G 29 R&B F7 Dm 38 COUNTRY C Am D 7 36 TANGO C 27 BOOGIE WOOGIE F Dm7 CFG B F =160 35 SAMBA 26 HEAVY METAL C G7 34 BOSSA NOVA Am C G7 A7 F7 C C7 C7 C7 F7 24 SOUL BALLAD C C7 C7 23 FUNK G F7 32 JAZZ WALTZ Am7 C7 =160 31 JAZZ BLUES =120 G7 14 C C  One Touch Setting List Turning on the One Touch Setting function, the following voice and tempo is automatically selected.
