What’s Wrong
Power switch not on.
Power supply not connected.
Bad power supply.
Improper supply.
Software values are out of range (unit has “crashed”). As
with all computing devices, crashes can be caused by any
loss of power while the unit is NOT sitting idle. Machine is
in idle when in either the Pattern or Song select pages
(i.e., not playing or recording). Crashes can also be
caused by errors during tape loads or corrupted MIDI sys
ex loads. It is recommended that data be saved and
verified frequently to prevent losses of large amounts of
data.
