Troubleshooting
Tyros3 Owner’s Manual • 107
Not all simultaneously played notes
sound.
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.
Style playback seems to “skip” when
the keyboard is played.
Some characters of the file/folder
name are garbled.
The language settings have been changed. Set the appropriate language
for the file/folder name (page 17).
An existing file is not shown. • 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 charac-
ters to 50 or less.
When connecting the Tyros3 to a
computer, the computer freezes.
An old USB-MIDI driver which is incompatible with the Tyros3 has
been installed to the computer. Disconnect the Tyros3 from the com-
puter 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).
The Voice selected from the Voice
Selection display does not sound.
Check whether or not the selected part is turned on (page 38).
When a Voice is changed, the previ-
ously selected effect is changed.
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).
The Voice produces excessive noise. 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 set-
tings.
Some Voices jump an octave in
pitch when played in the upper or
lower registers.
Some Voices have a pitch limit which, when reached, causes this type of
pitch shift. This is normal.
The Style does not start even when
the [START/STOP] button is
pressed.
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.
The Style does not start, even when
Synchro Start is in standby condi-
tion and a key is pressed.
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.
Only the rhythm channel of Style
plays.
•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.
Auto accompaniment chords are
recognized regardless of the Split
Point or where chords are played on
the keyboard.
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.
Auto accompaniment chord does
not change even when a different
chord is played or the chord is not
recognized.
•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).
