Data is not saved correctly in the
CompactFlash card
It is possible that the power was turned off while data
was being written into the CompactFlash 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 CompactFlash
card has been destroyed. Additional malfunctions may occur
if you attempt to continue using the card. Please format the
CompactFlash card. (p. 45).
* When you format the CompactFlash 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. 69)
Is the external MIDI device set to transmit MIDI clock
messages?
Some devices have a setting that turns MIDI clock
transmission on/off. 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-555 is able to synchronize?
The SP-555 can synchronize to a tempo in the 40–200
range. It may be unable to synchronize to a tempo that is
outside this range.
