Phenomenon
Storage is not possible.
Setting the time signature and number of measures is
not possible.
The playback timing of the rhythm pattern is different
from the timing with which it was recorded.
The Disk Drive produces a noise during recording or
playback.
When the procedure to load from a disk is performed,
the contents of the keyboard memory are erased.
Data cannot be exchanged through MIDI terminals.
The sound quavers or is distorted.
Noise from a radio or TV can be heard.
The cabinet becomes warm during use.
• The remaining memory capacity of the COMPOSER is 0.
• The time signature and number of measures cannot be changed
for a pattern which is currently recorded in the COMPOSER. If
you wish to change the time signature and/or measure data,
first follow the procedure to clear the memory.
• The QUANTIZE function was on when the pattern was recorded
and the timing was automatically corrected. Set the quantize
level to a smaller note unit or to OFF when recording.
• This occurs when the Disk Drive is reading a disk. It does not
indicate a problem.
• When performing the load operation from a disk, this
instrument's memory changes to that of the data loaded from
the disk. If you wish to preserve a song which is stored in this
instrument's memory, save it on a disk before performing the
load procedure.
• The switch for the COMPUTER terminal is not set to MIDI. Turn
off the power to this instrument and set the switch to MIDI.
• Match the channels on the transmitting side and the receiving
side.
• When the COMPUTER terminal or both the MIDI IN and OUT
terminals are connected to a computer, depending on the
computer software the received data may be sent back to the
instrument just as it is. Because of this the sound generated
from the keys and the sound generated from the returned data
are both produced, causing undesirable effects, such as the
sounds canceling each other out, for example. In this case,
either change the software settings to prevent received data
from being returned, or set the MIDI LOCAL CONTROL to off.
• This sometimes occurs when electrical equipment such as a
radio or TV is used near the instrument. Try moving such
electrical equipment further away from the instrument.
• The sound may be coming from a nearby broadcast station or
amateur radio station. If the sound is bothersome, consult your
dealer or service center.
• This instrument has a built-in power source that heats the
cabinet to some degree. This is not an indication of trouble.
