Tyros2 Owner’s Manual
In the Hard Disk Recorder function, an
error message appears and audio cannot be
recorded to the installed hard disk drive.
The data on the hard disk drive is fragmented and cannot be used as is. Since there is
no Defrag 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 67), 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.
The Vocal Harmony effect sounds distorted
or out-of-tune.
Your vocal microphone may be picking up extraneous sounds, such as the style sound
from the Tyros2. In particular, bass sounds can cause mistracking of the Vocal Har-
mony. 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.
• Separate the microphone from the external speakers as much as possible.
• Cut the Low band via the 3 Band EQ function in the MIC SETUP display (page
177).
When a voice is changed, the previously
selected effect is changed.
This is normal, each voice has its own suitable preset values which are automatically
recalled when the corresponding Voice Set parameters are turned on (page 188).
There is a slight difference in sound quality
between notes played on the keyboard.
This is normal and is a result of the Tyros2’s sampling system.
Some voices have a looping sound.
Some noise or vibrato is noticeable at higher
pitches, depending upon the voice.
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 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 (page 153).
The displayed disk free area value does not
coincide with the actual value.
The displayed value is an approximate value.
Appropriate harmony notes are not pro-
duced by the Vocal Harmony feature.
Make sure you are using the appropriate method to specify the harmony notes for the
current Vocal Harmony mode. See page 178.
The voice produces excessive noise.
Certain voices may produce noise, depending on the Filter (Harmonic Content/
Brightness) or EQ settings of the Mixing Console Filter. This is unavoidable due to
the sound generation and processing system of the Tyros2. To avoid noise, change the
above mentioned settings.
The sound is distorted or noisy.
• The MASTER VOLUME control may be turned up too high.
• 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.
• Is the gain of the Low band set too high in the Master EQ display (Mixing Con-
sole—page 184)?
A strange “flanging” or “doubling” sound
occurs.
• Are the RIGHT 1 and RIGHT 2 parts set to “ON”, for example, and both parts set
to play the same voice?
• If you are routing the MIDI OUT on the Tyros2 to a sequencer and back to the MIDI
IN, you may want to set Local Control (page 215) to “off” to avoid MIDI “feed-
back.”
The sound is slightly different each time the
keys are played.
The Main display does not appear even
when turning the power on.
This may occur if a hard disk has been installed to the Tyros2. Installation of some
hard disk units may result a long interval between turning the power on and appear-
ance of the Main display.
The function assigned to the pedal does
not operate correctly.
You can assign some functions to the pedal—punch in/out of Song/Hard Disk
Recorder (pages 122, 143), Registration Sequence (page 173) and many functions
from the Function display (page 189). If you assign multiple functions to the pedal,
the priority is:
Punch in/out of Song or Hard Disk Recorder > Registration Sequence > Functions
