Chapter 1 Try Playing Some Sounds
Connecting to a Computer
This section explains how to connect the GI-20 to your
computer with a USB cable and use it as a tool to input data
to sequencers and other devices.
No USB cable is included with the GI-20. You will need to
purchase a third-party USB cable separately.
Do not press [SELECT] or connect (or disconnect) any device
or cable to (or from) the USB connector during performances
or while operating sequencers or other devices with the
computer. This may cause malfunctioning of the computer or
MIDI sound module.
* First, follow the instructions in “Installing & Setup the
Driver” (p. 45) to install the GI-20 driver on your computer.
Setting the MIDI Port
This setting determines which MIDI data from the GI-20 is
used by the applications on your computer.
In the application’s MIDI device selection screen, select
“Roland GI-20 MIDI IN” as the input device and “Roland GI-
20 MIDI OUT” as the output device.
* For instructions on selecting the input device, refer to the
owner’s manual for the application you are using.

Roland GI-20 MIDI IN
This is the port used for inputting performance data to the
GI-20 from your computer.
Input here is performance data from guitars and basses
equipped with GK connectors.
Roland GI-20 MIDI OUT
This is the port used for outputting performance data to your
computer from the GI-20.
When MIDI PLAYBACK is set to ON, the performance data
the GI-20 receives from the computer is output as is from the
GI-20’s MIDI OUT connector (refer to “Setting the MIDI Data
Path (MIDI PLAYBACK)” p. 17).
Setting the MIDI Data Path
(MIDI PLAYBACK)
You can switch the MIDI messages that are output from
MIDI OUT. Set MIDI PLAYBACK to “Off” when you want to
output performance data input from the GK input directly
from the MIDI OUT connector. When you want to output
your computer’s MIDI performance data from the GI-20’s
MIDI OUT connector, for example, if you want to play the
computer’s MIDI data through an external MIDI sound
module, set this to “On.”
1. Turn the PARAMETER knob to “PLAY MODE.”

2. Press [SELECT] to set MIDI PLAYBACK to “On” or “Off.”
[SELECT] is lit when this is set to “On”; when set to
“Off,” [SELECT] is unlit.
* MIDI PLAYBACK cannot be set to “On” unless the computer
and the GI-20 are connected with a USB cable.
