Appendix Troubleshooting PROBLEM In the Hard Disk Recorder function, an error message appears and audio cannot be recorded to the installed hard disk drive. The Vocal Harmony effect sounds distorted or out-of-tune. When a voice is changed, the previously selected effect is changed. There is a slight difference in sound quality between notes played on the keyboard. 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. The style chord does not change even when a different chord is played or the chord is not recognized. The displayed disk free area value does not coincide with the actual value. Appropriate harmony notes are not produced by the Vocal Harmony feature. The voice produces excessive noise. The sound is distorted or noisy. A strange "flanging" or "doubling" sound occurs. The sound is slightly different each time the keys are played. The Main display does not appear even when turning the power on. The function assigned to the pedal does not operate correctly. POSSIBLE CAUSE/SOLUTION 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. 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 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. • 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). 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). This is normal and is a result of the Tyros2's sampling system. Some voices have a pitch limit which, when reached, causes this type of pitch shift. This is normal. • 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 value is an approximate value. Make sure you are using the appropriate method to specify the harmony notes for the current Vocal Harmony mode. See page 178. 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 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)? • 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 "feedback." 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 appearance of the Main display. 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 226 Tyros2 Owner's Manual
