10. Troubleshooting
Q: The PC-300 cannot be switched on or
doesn’t work at all.
A: Check if you are using the correct AC
adapter. (Use only the specified adapter).
A: Check the setting of the POWER switch:
set it to “ON (DC IN)” if you are using
the supplied adapter, and to “ON (USB)”
when powering the PC-300 via the USB
connector. Do not forget to establish a
USB connection with your computer.
Q: The sound module does not respond to the
movements of the DATA ENTRY slider.
A: Check whether the correct function is
assigned to the DATA ENTRY slider.
Also, note that the module will some-
times not respond if the slider is moved
only slightly. If you are unsure, pull the
slider all the way down first and then set
it to the desired position.
A: Check the PC-300’s MIDI transmit
channel (see page 11) and set it so that it
corresponds to the Part’s or module’s
receive channel.
Q: The sound you have requested cannot be
selected.
A: Some GS modules, such as those in the
Sound Canvas series, have a switch
which allows you to turn on or off the
reception of Program Change messages
and/or Bank Select messages. Be sure this
switch is turned ON.
A: Could the sound module have received a
GM System On message (the message
that tells a module to function as a
General MIDI sound module) before
you sent Bank Select messages? Since
Bank Selects are not recognized by the
General MIDI System Level 1 specifica-
tions, the module will ignore them if it is
currently behaving as a General MIDI
device. To correct this situation, send a
GS Reset message (which retrieves the
GS default settings), or simply switch the
module off, then on again.
Note: The PC-300 cannot transmit GS Reset
messages.
A: Did you transmit the complete sequence
of values (“H”, “L” and Program
Number)? The PC-300 always transmits
CC00/CC32/PC clusters, even if only the
