Possible Cause and Solution
Transposition and Pitch control data, among others, cannot be memorized
(except as song data). (See page 62.)
The current settings keep the voice from sounding. Make sure that the
volume of the voice is set to a suitable level, and adjust the various
parameters in the Voice Edit display until the voice can be heard.
1) Problems in recording or playback may be caused by improper operation
of the M.D.R. Refer to the LED Display Messages chart on page 87.
2) The PLAY or RECORD section buttons for selecting parts may be
turned off. Turn on the appropriate PLAY or RECORD buttons.
If some song numbers contain a large amount of recorded data, the disk
may not have enough available memory left to record the normal maximum
of 40 songs.
The amount of recorded data on the disk is close to the maximum limit.
Either use another disk or delete the data of any unnecessary song number.
1) When recording, you forgot the following operation: press the RECORD
button, then hold down the SHIFT button while you press the UPPER
button (selecting Lead).
2) During playback, you forgot to set the LEAD PLAY button to on.
The M.D.R. is designed so that the rhythm cannot be started at the very
beginning of a recording. If you wish to use the rhythm, start it after the
available memory display appears on the M.D.R. display.
During playback, you removed the disk by pressing the EJECT button.
Whenever you wish to stop playback, always press the STOP button.
