• Is the serial port selected correctly?
It is possible that the serial port (COM port) you selected in the Roland Serial MIDI Driver Settings
dialog box is being used by another device, or has not been detected by the system.
Connect the SD-20 to a different serial port, and change the settings appropriately. ->"Settings and
checking" (p. 39)
• Are the track outputs set correctly?
MIDI tracks to which no MIDI playback device is assigned will not be heard. If you want to play
back a MIDI track, you must make sure that the MIDI device you want to use is displayed in your
software as the MIDI output port. For details, refer to the owner's manual for your software.
• Is it possible that you have the Computer switch set to MIDI, even though the SD-20 is
connected via USB?
If you intend to use a USB connection, set the Computer switch to USB.
You must not use a USB cable to connect the SD-20 to your computer if the Computer switch
remains set at MIDI.
