Which serial port should I use?

Most computers let you use up to four serial ports (COM1--COM4).
In the "COM Ports" field, select the serial port (COM port) that you will use to connect your sound
module.
Be aware of two points.
• You must use a serial port that is not being used by another device.
• You must use the serial port that corresponds to the serial connector to which your sound module
is connected.

To determine which serial port corresponds to the serial connector to which your sound module is
connected, refer to the owner's manual for your computer or contact the manufacturer of your
computer. Depending on the internal connections of your computer, the serial connector may not
be connected to any of the serial ports (COM1--COM4). In this case, refer to the owner's manual for
your computer, and change the settings.

How many MIDI OUT ports can I use?

If [Use multiple ports] is checked, you will be able to use the multiple ports of the SD-20 from your
computer via the Roland serial MIDI driver.
When you use multiple ports, you will be able to use two MIDI OUT devices and two MIDI IN
devices from your computer.
Select [SD-20] in the "Sound module" field. With this setting, you will be able to use two MIDI OUT
ports and two MIDI IN ports from your computer.

Using flow control

The SD-20 supports CTS/RTS Flow Control, a control function that temporarily pauses data
transmission/reception. By checking [Activate CTS/RTS Flow Control], you may be able to avoid
problems with transmitting performance data.
