Problem Points to check Action
Acoustic feedback
(a whine or howl) is
heard
Howling could be produced depending on the
location of mics relative to speakers.
This can be remedied by:
1. Changing the orientation of the mic(s).
2. Relocating mic(s) at a greater distance from speakers.
3. Lowering volume levels.
Can’t sample
Is it possible that your SD card doesn’t have any more
free space?
If there is insucient memory, the display will indicate “
FUL” (Memory Full) when you
attempt to sample. Delete unneeded samples to increase the amount of free memory
(p. 21).
Is the SD card inserted correctly? Make sure that the SD card is inserted correctly (p. 10).
Is the SD card formatted correctly? Format the SD card using the SP-404SX (p. 35).
Are samples assigned to all pads?
You can’t sample if there are no vacant pads. Delete unwanted samples to free up some
pads (p. 21).
Could [PATTERN SELECT] button be lit?
If the [PATTERN SELECT] button is lit, you’re recording patterns, and will not be able to
sample.
Press the [PATTERN SELECT] button so its light is turned o.
Could [DEL] button be lit or blinking?
If the [DEL] button is lit or blinking, you are deleting samples, and will not be able to
sample. Press the [CANCEL] button (p. 21).
Excessive noise or
distortion in the
sampled sound
Is the input level appropriate?
The sampled sound will be distorted if the input level is too high, and if the level is too
low there will be excessive noise. Adjust the volume of the connected device so that the
PEAK indicator lights occasionally (p. 19).
Are the eect settings appropriate?
Some types of eect will make the level higher than the original sample, or may distort
the sound itself. Some eects also emphasize the noise. Try turning the eect o, and
check whether the noise or distortion is present in the original sample itself. Then adjust
the eect settings appropriately.
Could you be playing more than one sample
simultaneously?
Even if the level of each sample is appropriate, playing multiple samples simultaneously
will raise the overall level excessively, possibly causing distortion. Lower the level of each
sample to avoid distortion.
If the sound won’t
stop!
Press the [CANCEL] button four times in rapid succession. All of the SP-404SX’s sounds
will stop.
Displayed BPM value
is wrong
If the sampled time is multiple measures or less than
one measure, the BPM indication may be double
or half.
Press the [TIME/BPM] button so the button is lit, then turn the [CTRL 2] (BPM) knob to set
the desired value. Refer to “Changing a Sample’s BPM” (p. 30).
In some cases, such as if the length of the region is three beats, it may not be possible to calculate or adjust the BPM value correctly.
An inserted SD card
is not recognized, or
its data cannot be
selected
Is the SD card inserted correctly? Check the SD card.
Is the SD card an appropriate type? Use an SD card or an SDHC card. Other types of cards cannot be used.
Is the SD card formatted correctly?
SD cards formatted by a device other than the SP-404SX cannot be used. Please format
the SD card (p. 35).
Data is not saved
correctly in the SD
card
It is possible that the power was turned o while data
was being written into the SD card (i.e., while the dot
was blinking in the display). The lost data cannot be
recovered.
In this case, it is possible that all data in the SD card has been destroyed. Additional
malfunctions may occur if you attempt to continue using the card. Please format the SD
card (p. 35).
When you format the SD card, all data in the card will be lost.
Pattern sequencer
does not synchronize
to an external MIDI
device
Have you made the correct settings so that the
pattern sequencer can synchronize?
Check the settings (p. 47).
Is the external MIDI device set to transmit MIDI clock
messages?
Some devices have a setting that turns MIDI clock transmission on/o. Also, some
external devices, such as sequencers, transmit MIDI clock only during playback.
Does the tempo of the external MIDI device exceed
the tempo range to which the SP-404SX is able to
synchronize?
The SP-404SX can synchronize to a tempo in the 40–200 range. It may be unable to
synchronize to a tempo that is outside this range.
