Tyros3
Owner's Manual

Troubleshooting

PROBLEM
When using a mobile phone, noise is produced.

POSSIBLE CAUSE/SOLUTION
Using a mobile phone in close proximity to the Tyros3 may produce interference. To prevent this, turn off the mobile phone or use it further away from the Tyros3.

PROBLEM
The Main display does not appear even when turning the power on.

POSSIBLE CAUSE/SOLUTION
This may occur if a hard disk or USB storage device has been installed to the Tyros3. Installation of some hard disk units/USB storage devices may result a long interval between turning the power on and appearance of the Main display.

PROBLEM
In the LCD display, there are some black points (unlit) or white points (always lit).

POSSIBLE CAUSE/SOLUTION
These are the result of defective pixels and occasionally occur in TFT-LCDs; they do not indicate a problem in operation.

PROBLEM
The overall volume is too low, or no sound is heard.

POSSIBLE CAUSE/SOLUTION
The master volume may be set too low. Set it to an appropriate level with the [MASTER VOLUME] dial.
If volume control is assigned to the foot controller or [ASSIGN] slider, set it to an appropriate level. 
All keyboard parts are set to off. Use the PART ON/OFF [RIGHT 1]/[RIGHT 2]/[RIGHT 3]/[LEFT] button to turn it on (page 38).
Make sure the desired channel is set to on in the CHANNEL display (pages 54, 63). 
The volume of individual parts may be set to low. Raise the volume in the BALANCE display (page 55).
Check whether the external speaker is connected properly (pages 88, 100).
Headphones are connected, disabling the speaker output. Unplug the headphones.
A plug is inserted in the LOOP SEND jacks. Unplug the LOOP SEND jacks.
Is the footswitch connected to the appropriate jack?
The [FADE IN/OUT] button is on, muting the sound. Press the [FADE IN/OUT] button to turn the function off.
Has a Voice been selected from the Expansion Voice Bank? The Expansion Voice Bank is a bank for saving Voices that you have created or obtained via Internet, etc., and is empty by default.

PROBLEM
The sound is distorted or noisy.

POSSIBLE CAUSE/SOLUTION
The volume may be turned up too high. Make sure all relevant volume settings are appropriate.
This may be caused by the effects. Try cancelling all unnecessary effects, especially distortion-type effects.
Some filter resonance settings in the Voice Set display can result in distorted sound. Adjust these settings if necessary.
Is the gain of the Low band set too high in the EQ Page of the Mixing Console display (page 78)?

PROBLEM
The keyboard volume is lower than the Style/Song playback volume.

POSSIBLE CAUSE/SOLUTION
The volume of the keyboard parts may be set too low. Raise the volume in the BALANCE display (page 55).
The [ASSIGN] slider may be set to a low level. (By default, keyboard volume is assigned to the [ASSIGN] slider.) Set it to an appropriate level.

PROBLEM
A strange "flanging" or "doubling" sound occurs.

POSSIBLE CAUSE/SOLUTION
Are the RIGHT 1 and RIGHT 2 parts set to "ON," and are both parts set to play the same Voice?
If you are routing the MIDI OUT on the Tyros3 to a sequencer and back to the MIDI IN, you may need to set Local Control setting to "off" in the SYSTEM Page of the MIDI display (page 110).

PROBLEM
The sound is slightly different each time the keys are played.

POSSIBLE CAUSE/SOLUTION
Are the RIGHT 1 and RIGHT 2 parts set to "ON," and are both parts set to play the same Voice?
If you are routing the MIDI OUT on the Tyros3 to a sequencer and back to the MIDI IN, you may need to set Local Control setting to "off" in the SYSTEM Page of the MIDI display (page 110).

PROBLEM
Not all simultaneously played notes sound.

POSSIBLE CAUSE/SOLUTION
You are probably exceeding the maximum polyphony of the Tyros3. The Tyros3 can play up to 128 notes at the same time-including RIGHT 1/RIGHT 2/RIGHT 3/LEFT Voices, Style, Song, and Multi Pad notes. When the maximum polyphony is exceeded, the least important notes (such as soft notes and notes currently decaying) will stop sounding first.

PROBLEM
Style playback seems to "skip" when the keyboard is played.

POSSIBLE CAUSE/SOLUTION
You are probably exceeding the maximum polyphony of the Tyros3. The Tyros3 can play up to 128 notes at the same time-including RIGHT 1/RIGHT 2/RIGHT 3/LEFT Voices, Style, Song, and Multi Pad notes. When the maximum polyphony is exceeded, the least important notes (such as soft notes and notes currently decaying) will stop sounding first.

PROBLEM
Some characters of the file/folder name are garbled.

POSSIBLE CAUSE/SOLUTION
The language settings have been changed. Set the appropriate language for the file/folder name (page 17).

PROBLEM
An existing file is not shown.

POSSIBLE CAUSE/SOLUTION
The file extension (.MID, etc.) may have been changed or deleted. Manually rename the file, adding the appropriate extension, on a computer.
Data files with names of more than 50 characters cannot be handled by the instrument. Rename the file, reducing the number of characters to 50 or less.

PROBLEM
When connecting the Tyros3 to a computer, the computer freezes.

POSSIBLE CAUSE/SOLUTION
An old USB-MIDI driver which is incompatible with the Tyros3 has been installed to the computer. Disconnect the Tyros3 from the computer and uninstall the old driver, then install the latest USB-MIDI driver. The latest driver can be downloaded from Yamaha website (http://music.yamaha.com/download).

PROBLEM
The Voice selected from the Voice Selection display does not sound.

POSSIBLE CAUSE/SOLUTION
Check whether or not the selected part is turned on (page 38).

PROBLEM
When a Voice is changed, the previously selected effect is changed.

POSSIBLE CAUSE/SOLUTION
Each Voice has its own suitable preset settings, which are automatically recalled when a Voice is selected. To avoid this, turn the Voice Set parameter off in the VOICE SET Page of the REGIST SEQUENCE/FREEZE/VOICE SET display (page 110).

PROBLEM
The Voice produces excessive noise.

POSSIBLE CAUSE/SOLUTION
Certain Voices may produce noise, depending on the Filter (Harmonic Content/Brightness) or EQ settings of the Mixing Console display. This is unavoidable due to the sound generation and processing system of the Tyros3. To avoid noise, try changing the above mentioned settings.

PROBLEM
Some Voices jump an octave in pitch when played in the upper or lower registers.

POSSIBLE CAUSE/SOLUTION
Some Voices have a pitch limit which, when reached, causes this type of pitch shift. This is normal.

PROBLEM
The Style does not start even when the [START/STOP] button is pressed. 

POSSIBLE CAUSE/SOLUTION
The Rhythm part of the selected Style may not contain any data. Turn the [ACMP] button on and play the left-hand section on the keyboard to sound the accompaniment part of the Style.

PROBLEM
The Style does not start, even when Synchro Start is in standby condition and a key is pressed.

POSSIBLE CAUSE/SOLUTION
You may be trying to start a Style by playing a key in the right-hand range of the keyboard. When the [ACMP] button is on, you need to play a key in the left-hand (chord) range of the keyboard to start the Style with Synchro Start.

PROBLEM
Only the rhythm channel of Style plays.

POSSIBLE CAUSE/SOLUTION
Make sure that the [ACMP] button is turned on.
You may be playing keys in the right hand range of the keyboard. Make sure to play keys in the chord range of the keyboard.

PROBLEM
Auto accompaniment chords are recognized regardless of the Split Point or where chords are played on the keyboard.

POSSIBLE CAUSE/SOLUTION
This is normal if the fingering mode is set to "Full Keyboard" or "AI Full Keyboard" in the CHORD FINGERING display (page 110). If either of these is selected, chords are recognized over the entire range of the keyboard, irrespective of the split point setting.

PROBLEM
Auto accompaniment chord does not change even when a different chord is played or the chord is not recognized.

POSSIBLE CAUSE/SOLUTION
Are you sure you're playing on the left-hand section of the keyboard?
You may be using single-finger type fingering. Change the fingering mode in the CHORD FINGERING display (page 110).

PROBLEM
Song playback does not start.

POSSIBLE CAUSE/SOLUTION
If the Song is write-protected ("Prot. 2 Edit" is shown at the upper left of the Song name): 
The original file may not be in the same folder. It cannot be played back unless the original file (showing "Prot.2 Orig" at the upper left of the Song name) is in the same folder.
The original file name may have been changed. Rename the file with the original file name (so that "Prot.2 Orig" is shown at the upper left of the Song name).
The file icon may have been changed. Songs to which write-protect has been applied cannot be played back when the file icon of the original has been changed.

PROBLEM
The vibrato effect applied when a Song is recorded sounds different when it is played back.

POSSIBLE CAUSE/SOLUTION
This may occur when you use SA2 Voices which have their own default vibrato value. Depending on the Modulation wheel position, the default vibrato value may be recorded or the modulation wheel value may be recorded, regardless of the actual vibrato sound you have played. To remedy this:
Select a Voice AFTER you set the Modulation wheel to minimum (down) position.
If you want to cancel the vibrato effect, set the Modulation wheel to minimum position AFTER Song recording starts.

PROBLEM
An audio song cannot be copied or cut.

POSSIBLE CAUSE/SOLUTION
The audio song file name (which contains the file path, internally) may be too long. Shorten the song name or copy/paste the file to a higher folder level.

PROBLEM
In the Hard Disk Recorder function, an error message appears and audio cannot be recorded to the installed hard disk drive.

POSSIBLE CAUSE/SOLUTION
The data on the hard disk drive is fragmented and cannot be used as is. Since there is no defragmentation function in the Hard Disk Recorder, the drive can only be defragmented by formatting it. To do this, first back up the data to a computer by using the USB storage mode (page 97), then format the drive, and finally copy the data back to the drive (using the USB storage mode again). Performing this copy/restore operation effectively defragments the drive, allowing you to use it again.

PROBLEM
The Vocal Harmony effect sounds distorted or out-of-tune.

POSSIBLE CAUSE/SOLUTION
Your vocal microphone may be picking up extraneous sounds, such as the Style sound from the Tyros3. In particular, bass sounds can cause mistracking of the Vocal Harmony. To remedy this:
Sing as closely to the microphone as possible.
Use a directional microphone.
Turn down the Master volume, Style volume, or Song volume control (pages 16, 55).
Separate the microphone from the external speakers as much as possible.
Cut the Low band via the 3 Band EQ function in the MICROPHONE SETTING display (page 109).
Raise the microphone input level (TH) via the Compressor function in the MICROPHONE SETTING display (page 109).

PROBLEM
Appropriate harmony notes are not produced by the Vocal Harmony feature.

POSSIBLE CAUSE/SOLUTION
Try to change the Vocal Harmony Control setting in the OVERALL SETTING Page of the Microphone Setting display (page 109). Also make sure to use the appropriate method to specify the harmony notes for the selected Vocal Harmony mode. Refer to the Reference Manual.
