Tyros4 Owner's Manual
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.
The file format may not be compatible with the instrument. The compatible formats are:
MP3 and WAV. The DRM protected files cannot be played back.
The audio playback volume has been changed. Setting the volume value to 90 plays
back the file as the same volume when it was recorded (page 80).
The audio song file name (which contains the file path, internally) in the internal HDD
may be too long. Shorten the song name or copy/paste the file to a higher folder level.
The data on the hard disk drive is fragmented and cannot be used as is. Since there is
no defragmentation function in the Audio Recorder/Player, the drive can only be defrag-
mented by formatting it. To do this, first back up the data to a computer by using the
USB storage mode (page 103), 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.
When changing the rhythm/percussion Voices (drum kits, etc.) of the Style and Song
from the VOICE parameter, the detailed settings related to the drum voice are reset,
and in some cases you may be unable to restore the original sound. In the case of
Song playback, you can restore the original sound by returning to the beginning of the
Song and playing back from that point. In the case of Style play, you can restore the
original sound by selecting the same Style again.
The microphone input signal cannot be recorded by Song recording. Use the Audio
Recorder/Player function (page 76).
Vocal Harmony is set to on. Turn Vocal Harmony off (page 83).
Your vocal microphone may be picking up extraneous sounds, such as the Style sound
from the instrument. 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 (pages 16, 53).
• Separate the microphone from the external speakers as much as possible.
Turn the instrument's power off, then turn on again without pressing the footswitch.
The output volume of the external device connected to this instrument is too low.
Increase the output volume of the external device. The volume level reproduced via this
instrument can be adjusted by using the [MASTER VOLUME] control.
An old USB-MIDI driver which is incompatible with the instrument has been installed to
the computer. Disconnect the instrument 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-tyros.com/).
