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
