Troubleshooting
Even though you set a tone’s pan all the way to
one channel, sound is still heard from the
opposite channel
The SD-50’s built-in effects are stereo. This means that if
you’ve applied an internal effect, the effect sound will still be
heard from the opposite channel even if a tone is panned all
the way to one side.
The sound becomes strange when you play high
notes
Playing high notes on the SD-50 might produce an
unexpected result, including no sound at all, failure of the
sound to go higher in pitch, or noise that changes depending
on the key you play (warbling, chirping, beeping, buzzing,
etc.)
This is mainly caused by exceeding the limit of high notes
that the SD-50 is able to produce; this occurs for notes that
are not normally played, and does not indicate a malfunction.
Insufficient volume from a device connected to
the SD-50’s INPUT
Could you be using a connection cable that contains a built-
in resistor?
Use a connection cable that does not contain a resistor.
Effect not applied
Check the following points.
• Are the various effect settings appropriate? (p. 51)
• There will be no effect if the corresponding effect’s send level
is at 0. Check the settings.
• Even if the effect’s send level is above 0, there will be no
effect if the multi-effect output level, chorus level, or reverb
level are at 0. Check these settings.
The effect is difficult to notice even if you raise
the chorus or reverb send level of each part
The send level to the chorus and reverb effects can be
specified for each part, but these values specify the amount
that will be used of the patch’s own chorus and reverb send
levels.
This means that even if these are set to their maximum value
of 127, there will be no effect if the send level of the patch
you’re using has been lowered.
If you want to apply the effect more deeply, you’ll need to
edit the settings of the patch. The patch’s send levels to
chorus and reverb can be specified separately depending on
whether you’re using multi-effects.
Settings are different than those saved in the
studio set
Check the following points.
• The settings of the mastering effect may have changed.
(These settings are not included in the studio set.)
Playback on your external sequencer lags or is
interrupted
If the playback lags or is interrupted, it is likely that the
sequencer or sound module is experiencing a heavy
processing load.
Here are the main causes and what you can do about them.
• Could the polyphony be exceeding 128?
Try reducing the number of notes that are played
simultaneously.
• Could a large amount of data be concentrated at the
beginning of a beat in the sequence data?
Try staggering the timing by one or two clocks so that data
does not occur at the same timing.
It’s easy for song data to be concentrated at the beginning of
a beat if you use step recording to create song data, or if you
apply quantization after real-time recording from a keyboard.
This may cause a large amount of data to be transmitted to
the SD-50 at the same time, causing playback to lag.
• Could there be program changes at the locations where the
playback lags?
Try changing the location of the program change data.
If you insert program changes in your song, processing time
may be required in order to switch tones, causing the
playback to lag.
