Press the [MAIN A] button.
COUNT INTRO MAIN/AUTO FILL INTRO SIMPLE ENDING ENDING
Press the [INTRO] button.
For this example, play a C major chord (as shown below). For information on how to enter chords, see Chord Fingerings on page 40.
The indicator of the destination section (MAIN A/ B/C/D) will flash while the corresponding fill-in is playing. During this time you can change the destination section by pressing the appropriate MAIN/AUTO FILL [A], [B], [C] or [D] button.
You can use the intro section even in the middle of the song by pressing the [INTRO] button during the song. If the MAIN/AUTO FILL A/B / C/D button is pressed after the final half beat (eighth note) of the measure, fill-in will begin from the next measure.
When the playback of the intro is finished, it automatically leads into main A section.
Press the [MAIN B] button.
If you press the INTRO/ COUNT INTRO button while the ending is playing, the intro section will begin playing after the ending is finished. If you press a MAIN/AUTO FILL button while the ending is playing, fill-in accompaniment will immediately start playing, continuing with the main section. If you press the [SYNC START] button while an accompaniment is playing, the accompaniment will stop and the PSR-740/640 will enter Synchronized Start standby status. You can begin the accompaniment by using the ending instead of the intro section.
A fill-in plays, automatically followed by the main B section.
Press the MAIN buttons as desired during your performance.
The main section corresponding to the pressed button plays following an automatic fill-in.
Press the [ENDING] button.
This switches to the ending section. When the ending is finished, the auto accompaniment automatically stops. You can have the ending gradually slow down (ritardando) by pressing the [ENDING] button again while the ending is playing back.

Tempo/Tap

Each style of the PSR-740/640 has been programmed with a default or standard tempo; however, this can be changed by using the [TEMPO/TAP] button. The following steps can be used even during playback.

* Set only when the accompaniment is not playing.
The Groove and Dynamics function on the PSR-740 lets you temporarily change the feel of the accompaniment. Specifically, it allows you to alter the timing, velocity and gate time of notes during playback of any of the accompaniment styles.
q Groove This lets you play the music with some swing or change the feel of the beat by making subtle shifts in the timing (clock) of the accompaniment style. Groove Type This determines the type of groove timing change. For example, the 16 to 8 setting converts all 16th notes to 8th-note timing. Groove Swing This determines how much swing feel is applied to the accompaniment. q Dynamics This changes the velocity (or accent) of certain notes in the accompaniment style to complement or enhance changes made to the Groove settings above. Dynamics Type This determines the type of dynamic change applied to the accompaniment. (Each type is a different template to which the timing of the velocity changes has been programmed.) Dynamics Depth This determines how strongly the selected dynamics type is applied to the accompaniment (expressed as a percentage). Higher values produce a stronger effect. Every time the [GROOVE] button is pressed, the values for the above Groove and Dynamics parameters are automatically set to best suit the selected style.
Applying Groove & Dynamics
Select a style and start the accompaniment (page 35). Press the [GROOVE ON/OFF] button.
The Groove & Dynamics effect will be applied to the accompaniment.
To cancel the groove effect, press the [GROOVE ON/OFF] button again. Stop the accompaniment (page 35).
Editing the Groove and Dynamics Effect
When you select a style and turn the [GROOVE ON/OFF] button on, the most suitable Groove and Dynamics settings for that style are automatically called up. In this way, simply turning the Groove function on lets you produce a variety of rhythm feels; however, you can also edit detailed parameters and change the Groove and Dynamic effect to your liking.

q The PSR-740/640 features special User style, User pad and Registration Memory functions. The data recorded with these functions can also be saved to disk individually or in any combination. Likewise, data (files) saved to disks can be loaded individually or in any combination to the PSR-740/640.

Using the Floppy Disk Drive (FDD) and Floppy Disks
Be sure to handle floppy disks and treat the disk drive with care. Follow the important precautions below.
s Cleaning the Disk Drive Read/Write Head
q Clean the read/write head regularly. This instrument employs a precision magnetic read/write head which, after an extended period of use, will pick up a layer of magnetic particles from the disks used that will eventually cause read and write errors. q To maintain the disk drive in optimum working order Yamaha recommends that you use a commerciallyavailable dry-type head cleaning disk to clean the head about once a month. Ask your Yamaha dealer about the availability of proper head-cleaning disks. q Never insert anything but floppy disks into the disk drive. Other objects may cause damage to the disk drive or floppy disks.

s Compatible Disk Type

3.5" 2DD and 2HD type floppy disks can be used.

After saving User style (161-163), User pad (banks 37-40), and Registration Memory (bank 01-32) data to a floppy disk, you can reload them into the PSR-740/640.

Press the [LOAD] button.

Select the file to be loaded.
Press the [NEXT] button to display the DATA TYPE selection screen. Select the data type to be loaded.
Data types that can be loaded All, Style, Pad, Regist Style+Reg. Style Multi Pad Regist

Please follow the steps as indicated in the chart above, since the actual operation differs depending on the selected data type.
Select the data to be loaded.
Use the data dial, the [+/YES] button or the [-/NO] button. When All is selected, go to step #10 skipping over steps #8 and #9.
Press the [NEXT] button to display the LOAD TO screen. Select the destination.
Press the [NEXT] button to display the Load operation screen.
When data is loaded from a floppy disk to the PSR740/640, the data already in the memory of the instrument will be replaced by the data on the disk. Save important data into a disk file before doing the Load operation.
Execute the Load operation.
Press the [+/YES] button to execute the Load operation. Press the [-/NO] button to abort the Load operation.
While data is loading, never eject the floppy disk or turn the power off.
The Load operation is completed.
An alert message may appear on the display, if a problem occurs that prevents the data from being loaded. (For example, the capacity of the PSR-740/640 [RAM] may be exceeded, something may be wrong with the floppy disk or the data from the disk may be corrupted, etc.).

Song Copy

This operation allows you to make backup copies of your important data. Primarily, this will come in handy when you are recording and editing song data. For example, if you are quantizing the track of a song (page 100) which makes permanent changes to the track making a backup copy of the song allows you to restore the original song data in case youre not satisfied with the results of the quantization. Having a dedicated backup disk for every song you work on is a good idea. In this way, you can save a new copy of the song each time you make an important edit to it.
Copying song data from one floppy disk to another
Prepare a backup disk by formatting it. One file can be copied at a time. As shown in the illustration below, first copy the desired file on the disk to internal memory, then copy it to the destination disk.

Whats MIDI?

No doubt you have heard the terms acoustic instrument and digital instrument. In the world today, these are the two main categories of instruments. Lets consider an acoustic piano and a classical guitar as representative acoustic instruments. They are easy to understand. With the piano, you strike a key, and a hammer inside hits some strings and plays a note. With the guitar, you directly pluck a string and the note sounds. But how does a digital instrument go about playing a note?
q Acoustic guitar note production q Digital instrument note production

Sampling Note

Tone Generator (Electric circuit)

Playing the keyboard

Pluck a string and the body resonates the sound.
Based on playing information from the keyboard, a sampling note stored in the tone generator is played through the speakers.
As shown in the illustration above, in an electronic instrument the sampling note (previously recorded note) stored in the tone generator section (electronic circuit) is played based on information received from the keyboard. So then what is the information from the keyboard that becomes the basis for note production? For example, lets say you play a C quarter note using the grand piano sound on the PSR-740/640 keyboard. Unlike an acoustic instrument that puts out a resonated note, the electronic instrument puts out information from the keyboard such as with what voice, with which key, about how strong, when was it pressed and when was it released. Then each piece of information is changed into a number value and sent to the tone generator. Using these numbers as a basis, the tone generator plays the stored sampling note.
q Example of Keyboard Information Voice number (with what voice) Note number (with which key) Note on (when was it pressed) and note off (when was it released) Velocity (about how strong) 01 (grand piano) 60 (C3) Timing expressed numerically (quarter note) 120 (strong)

q Press one of the [TRACK1]-[TRACK16] buttons to select a MIDI channel.
When a track is assigned to more than one MIDI channel, the data from that track is transmitted via the lowestnumbered channel. MIDI transmit track settings will be retained even after turning the power off. See page 159 for details. The initial default channel/ track settings are: ch. 1 = RIGHT1 ch. 2 = RIGHT2 ch. 3 = LEFT ch. 4 = OFF ch. 5 = OFF ch. 6 = OFF ch. 7 = OFF ch. 8 = OFF ch. 9 = RHYTHM SUB ch. 10 = RHYTHM MAIN ch. 11 = BASS ch. 12 = CHORD1 ch. 13 = CHORD2 ch. 14 = PAD ch. 15 = PHRASE1 ch. 16 = PHRASE2 To avoid MIDI loops which can cause operational errors, check the PSR-740/640 Local Control setting (page 132) and the MIDI THRU settings of any external MIDI devices.

* Right-hand keyboard playing and Left-hand keyboard playing indicate the performance played on the right side and left side of the keyboard from the split point, respectively. ** Outputs MIDI note data according to the respective octave settings for the voices R1, R2 and L.

MIDI Receive Setting

The PSR-740/640 can simultaneously receive data on all 16 MIDI channels, allowing it to function as a 16-channel multi-timbral tone generator. The Receive Channel and Receive Mode functions determine how each channel will respond to received MIDI data.

The default Local Control setting (factory setting) is ON.
Press the [NEXT] button to display the MIDI screen. Select Local Control.
Press the [NEXT] button to display the Local Control screen. Turn the Local Control on or off.
Reception of an external MIDI clock signal can be enabled or disabled as required. When disabled (INTERNAL), all of the time-based functions (Auto Accompaniment, SONG recording and playback, etc.) are controlled by its own internal clock. When MIDI clock reception is enabled (EXTERNAL), however, all timing is controlled by an external MIDI clock signal received via the MIDI IN terminal (in this case the PSR740/640 TEMPO setting has no effect). The default setting is INTERNAL.
Press the [NEXT] button to display the MIDI screen. Select Clock.
The default Clock setting (factory setting) is INTERNAL. When the Clock setting is EXTERNAL, AUTO ACCOMPANIMENT playback cannot be started via the panel [START/STOP] button, or started via the synchro start function. Also, the MULTI PAD playback cannot be initiated by pressing the MULT PADs. When the Clock setting is EXTERNAL, EC will appear on the TEMPO display, and tempo cannot be changed with the panel button.
Press the [NEXT] button to display the CLOCK screen. Set the Clock to INTERNAL or EXTERNAL.

Initial Setup Send

Transmits all current panel settings to a second PSR-740/640 or a MIDI data storage device. If you want to have the song play back with the panel settings used for recording, execute the Initial Data Send function before recording the performance on the PSR740/640 to an external sequencer.
Press the [NEXT] button to display the MIDI screen. Select Initial Setup Send.
Press the [NEXT] button to display the Initial Setup Send screen. Execute the Initial Setup Send operation.
Press the [+/YES] button to execute the INITIAL SEND operation. To abort the operation, press the [-/NO] button.

The Metronome cannot be turned on when free-tempo song data is selected in the Song mode. The tempo setting of some commercially available songs is fixed. These songs are called free-tempo software. When playing back freetempo song data on the PSR-740/640, the Tempo display shows - - - and the beat display does not flash. Also, the measure number in the display does not match the actual measure number of playback, and only gives you an indication of how much of the song has played back.
