Casio CTK-2090 User Manual page 39

Symptom
Some notes are cut off while they are playing.
The volume or tone setting I made has changed.
In certain keyboard ranges, the volume and tone
quality sound are slightly different from those in other
keyboard ranges.
With some tones, octaves do not change at the far
ends of the keyboard.
The pitch of the notes does not match other
accompanying instruments or sounds strange when
played long with other instruments.
The reverb of notes seems to change suddenly.
Sounds I sampled were deleted.
Even though I didn't input anything with the built-in
microphone, the message "Sampled!" appears on
the display when I release the SAMPLING button.
Rhythms played in the VOICE PERCUSSION Mode
sound strange and unnatural.
Operation
When I perform a skip forward or skip back
operation, the skip operation moves multiple song
measures instead of only a single measure.
Computer Connection
I can't exchange data between the Digital Keyboard
and a computer.
Action
Notes are cut off whenever the number of notes being sounded
exceeds the maximum polyphony value of 48 (24 for some tones).
This does not indicate malfunction.
• Adjust the main volume setting (page EN-6).
• Turn power off and then back on to initialize all Digital Keyboard
settings (page EN-6).
• Replace the batteries with new ones or switch over to AC adaptor
power (page EN-5).
This is due to system limitations. It does not indicate malfunction.

• Check and adjust the transpose (page EN-10) and tuning settings
(page EN-10).
• Turn power off and then back on to initialize all Digital Keyboard
settings (page EN-6).
• Check and adjust the reverb setting (page EN-9).
• Turn power off and then back on to initialize all Digital Keyboard
settings (page EN-6).
Be sure to press the power button to turn off power. Unplugging or
disconnecting the AC adaptor without first pressing the power button
to turn off power will cause sampled sounds to be deleted.
• Perform the sampling operation where it is quiet.
• You may be making noise, which is picked up as sampled sound,
when releasing the SAMPLING button release operation. If this is
the case, release the SAMPLING button carefully to avoid making
noise.
• Use the procedure under "Starting a Sampling Operation Manually"
(page EN-15) to turn off SampAuto, and then try manual sampling.
In order to assure proper balance for the rhythm, be sure to record all
five short samples. Playing a rhythm in the VOICE PERCUSSION
Mode while there is no short sample will cause a preset sample to
sound. If there is even a single short sample recorded, rhythm
instruments will sound only for the recorded short sample.
While song playback is stopped or a Step Up Lesson is in progress,
skip forward and skip back operations are performed in phrase units
(page EN-18).
• Check to make sure that the USB cable is connected to the Digital
Keyboard and computer, and that the device is selected correctly
with your computer's music software settings (page EN-32).
• Turn off the Digital Keyboard and then exit the music software on
your computer. Next, turn the Digital Keyboard back on and then
restart the music software on your computer.
