Troubleshooting

Does your computer meet the USB specifications?

If you are using a computer that does not fulfill the electrical requirements of the USB specifications, operation may be unstable. In this case, you may be able to solve the problem by connecting a USB hub.

If the above actions do not solve the problem, it is possible that the GI-20 has been incorrectly detected by the computer.

As described in “<Deleting incorrect device information>,” delete the incorrect device information, then re-install the

driver.

→ ”Installing & Setting Up the Driver (Windows)“ (p. 46)

“Found unknown device” appears even though you installed the driver

If your computer or USB hub has two or more USB connectors, and you connect the GI-20 to a USB connector to which the GI- 20 has never been connected before, the “Unknown device” dialog box may appear even on a computer onto which you have already installed the driver.

Refer to “Installing & Setting Up the Driver (Windows)”(p. 46), and install the driver once again. This is not a malfunction.

If the “Found unknown device” dialog box appears even though the GI-20 is connected to the same USB connector as before, it is possible that the computer has detected the GI-20 incorrectly.

As described in “<Deleting incorrect device information>,” delete the incorrect device information, then re-install the driver.

<Deleting incorrect device information>

1.Turn off the power of your computer, and start up Windows with all USB cables disconnected (except for keyboard and mouse).

2.After Windows restarts, use a USB cable to connect the GI- 20 to your computer.

3.Turn on the power of GI-20.

4.Click the Windows [Start] button, and from the menu that appears, choose “Settings Control Panel.”

5.Double-click the “System” icon.

The “System Properties” dialog box will appear.

6.In Windows XP/2000, select the System Properties Hardware tab, and click Device Manager.

In Windows 98, Click the “Device Manager” tab.

7.Check whether “Roland GI-20” with an “!” or “?” symbol is displayed below “Other Devices,” “Sound, Video, and Game Controllers,” or “Universal Serial Bus Controller.” If you find any such indication, select it and click [Delete].

8.A dialog box will ask you to confirm deletion of the device. Verify the contents of the dialog box, and then click [OK]. In the same way, delete all occurrences of “Roland GI-20” that have an “!” or “?” symbol.

9.Check whether “Composite USB Device,” “USB Device,” or “USB Composite Device” with an “!” or “?” symbol is displayed below “Other Devices,” “Sound, Video, and Game Controllers,” or “Universal Serial Bus Controller.” If you find any such indication, you need to determine whether it has appeared because the GI-20 has been detected incorrectly, or because there is a problem with some other device. To determine this, switch off the power of the GI-20.

If the “Composite USB Device” (or other) indication disappears when you turn off the power of the GI-20, then it is the GI-20 that has been incorrectly detected.

GI-20 specifications

The Roland GI-20 is a groundbreaking MIDI guitar converter that allows electric guitarists to explore the vast world of MIDI technology. Designed to bridge the gap between traditional guitar playing and digital music production, the GI-20 transforms standard guitar signals into MIDI data, giving players access to a wide array of synthesized sounds and virtual instruments.

One of the main features of the GI-20 is its ability to track the guitar’s pitch with high accuracy. Utilizing Roland’s advanced technology, the device boasts rapid response times and minimal latency, ensuring that every note plucked or strummed is translated into MIDI in real-time. This precision is crucial for guitarists who wish to maintain their playing style while experimenting with synthesizers and sampled instruments.

In terms of connectivity, the Roland GI-20 is equipped with a 13-pin connector, allowing it to interface seamlessly with compatible Roland synths, sound modules, and other MIDI devices. Additionally, standard MIDI outputs enable connection to MIDI controllers and computers, providing an expansive toolkit for music creation.

Guitarists can also customize their performance by altering the sensitivity levels, enabling them to fine-tune how the device responds to their playing style.

The GI-20 offers an array of built-in sounds that mirror the capabilities of traditional synthesizers. These sounds can be layered or split into different tones based on the player’s preferences, offering a variety of sonic textures to enhance compositions. Furthermore, the ability to save and recall user settings allows for quick access to preferred configurations during live performances.

Another significant characteristic of the GI-20 is its compatibility with a wide range of guitars, including both electric and bass guitars. As long as the instrument is equipped with the appropriate pickup system, the GI-20 can effectively convert its output into MIDI signals.

In summary, the Roland GI-20 is a versatile and innovative tool for guitarists seeking to expand their creative horizons. With its accurate tracking, extensive connectivity, user-friendly interface, and a wealth of sounds, it unlocks the potential for guitarists to dive into the realms of electronic music and MIDI composition.
