Cannot install the driver correctly
❏ Is the CD-ROM correctly inserted into your CD-ROM
drive?
Installation is not possible unless the CD-ROM included with
the GI-20 is inserted in your CD-ROM drive. Make sure that the
CD-ROM is correctly inserted into your CD-ROM drive.
❏ Is the CD-ROM or the lens of the CD-ROM dirty?
If the CD-ROM or the lens of the CD-ROM drive is dirty, the
installer may not work correctly. Clean the disc and/or lens
using a commercially-available CD cleaner or lens cleaner.
❏ Are you installing the software from a networked CD-
ROM drive?
The software cannot be installed from a networked CD-ROM
drive.
❏ Is there sufficient free space on your hard disk?
Delete unneeded files to increase the amount of free space.
After deleting the unneeded files, empty the recycling bin.
❏ Is the GI-20 connected correctly?
Make sure that the USB connector of your computer is
connected to the GI-20 by a USB cable. Check this, and if you
are using Windows, close the Sound and Multimedia Properties
dialog box (Sounds and Audio Devices Properties in Windows
XP, and Multimedia Properties in Windows 98), re-open the
same dialog box once again, and specify the audio and MIDI
input/output destinations.
→ “MIDI input and output destinations”(p. 57).
❏ Is the power of the GI-20 turned on?

❏ Using the procedure for “Deleting the driver”(p. 67),
delete the USB audio device driver installed in your
computer, and then re-install the GI-20 driver as
described in “Installing & setting Up the Driver
(Windows)”(p. 46).
Also check whether there is any “Other devices” in “Device
Manager” or “Unknown device” in “Universal Serial Bus
Controllers”. If you find any, delete them.

❏ Is OMS or FreeMIDI installed?
The GI-20 driver cannot be installed unless OMS or FreeMIDI
are installed. Please install OMS or FreeMIDI.

GI-20 is not detected when making
OMS or FreeMIDI settings
❏ Is the GI-20 detected?
Turn the power of the GI-20 off, then on again.
Reconnect the USB cable.
If other USB devices are connected, connect only the GI-20.
It is possible that the Macintosh did not correctly detect and
initialize the GI-20. Leave the GI-20’s USB cable connected, and
restart your Macintosh. If it is still not detected, shut down your
Macintosh, and then restart it.
The GI-20 will not be detected if it is connected to the USB
connector on the Macintosh keyboard.
Please connect the GI-20 to a USB connector on the Macintosh
itself.
❏ Are you using only OMS?
OMS will not work properly if FreeMIDI is installed in the same
system. Delete FreeMIDI-related files from the Extensions
folder.

❏ Is the USB cable connected correctly?
Make sure that the GI-20 and your computer are correctly
connected via a USB cable.
❏ Is USB enabled on your computer?
Refer to the operation manual for your computer, and make
sure that USB is enabled.
