Kawai X50-D Owner's Manual page 4

Some buttons do not light when you press them.
Problem: Check the following
Not every button is designed to light up. Please refer to the "Overall
Diagram and Explanation" on page B-4 of this manual to see which
buttons are supposed to light up when you press them.
The keyboard buttons light but the keys don't play.
Check the SYSTEM/MIDI functions to make sure that the LOCAL
mode is 'on'. If LOCAL mode gets turned "off" by mistake, the keys
will not play.
The Touch Response feature does not work.
Make sure that the TOUCH RESPONSE button is lit. If not, press it.
Most of the buttons do not work.
Only the SELECTOR and SOUND 1/2 buttons will be active in GMStd
mode. Select "Pro" MIDI mode to operate all buttons in normal fashion.
The front panel has a "cloudy" finish or has —
to "bubble" or "peel". This is not a defect.
There is a thin plastic film applied to the glossy panel (where the buttons
are located) for protection during shipping. You can remove this film
at any time. Use a fingernail to carefully lift up one of the edges, then
peel off the protective film.
You are using the SELECTOR buttons to select a
specific two-digit or three-digit number, but a
lower number appears in the display.
You may be taking too long to enter the second or third digits. Once
you enter the first digit, the keyboard waits for about one second to
see if a second or third digit will follow. If the second or third digit is
not entered within that one-second 'waiting period', the keyboard
assumes that you meant to enter a single-digit number only. Be sure
to enter all two-digit and three-digit numbers in rapid succession.
When using the ONE FINGER AD-LIB feature, the
sounds change by themselves.
The accompaniment will not start when you press
the START/STOP button.
When you try to record a song on the X50-D's
recorder, a previous song always play when you
start to record.
This is normal operation. When you first activate ONE FINGER
AD-LIB (OFA), specific sounds are pre-assigned to the OFA phrases.
If you select a sound and then turn OFA "on", the pre-assigned sounds
will appear. However, if you turn OFA on first and then select a sound,
your new sound will be assigned to all the OFA phrases.
The tempo may have been moved to SYNC mode, which deactivates
the START/STOP button. To escape SYNC mode, press the TEMPO
UP button until a number appears in the display. The accompaniment
should now begin when you press the START/STOP button.
Because the X50-D has overdubbing capability, the recorder will record
over any song currently in memory. Use the ERASE procedure (press
both the REC/END and PLAY/STOP buttons simultaneously twice)
to clear the existing song. Then try recording again.
The RECORDER suddenly stops or will not record.
The keyboard only plays drum sounds.
This usually happens when you have exceeded the RECORDER's
memory capacity. Use the ERASE procedure above to clear the memory.
Then, begin recording again.
The DRUM SET sound (#129) has probably been selected. Use the
Sound 1 and SELECTOR buttons to select a different sound (refer to
the 'Selecting Sounds" section of the manual).
The AUTO function is not working properly.
+
Check to see if someone has set your keyboard to operate in AUTO
2 or AUTO 3 modes. These alternative modes are different from the
normal AUTO 1 style of auto-accompaniment. (Please refer to the
"Advanced Use of Auto-Accompaniment" section of this manual.)
The ONE FINGER AD-LIB feature will not work. Check to see if someone has set your keyboard to operate in AUTO
2 of AUTO 3 modes. One Finger Ad-Lib will not operate when the
keyboard is in one of these two modes.
The keyboard is not sending complete accompani-
ment note information via MIDI.
See the MIDI section of this manual. The ACCOMPANIMENT MIDI
OUT function must be set to "on". Otherwise, the keyboard will only
send "note" information (notes that are actually played) via MIDI.
The Sustain function will not work.
The Variation button does not work.
Sustain will not work with percussive sounds such as sound number
114 AGOGO or sound number 116 WOODBLOCK.
The Variation Pattern does not work with Styles 99 and 100.
