II. UPDATING THE OS FROM WINDOWS USING MIDI-OX

Before starting, close all other audio or MIDI or DAW software, and disconnect all other MIDI devices. If necessary, download and install MIDI-OX.

To prepare the TRIGON-6 to receive system exclusive messages:

1. Press the Globals button once to enter the top row of the Global menu.
2. Press program button #8, which is labeled “MIDI SysEx.”
3. Using the Bank/Tens Inc/Dec buttons, change the MIDI SysEx cable to select either MIDI DIN or USB. If you’re using USB to update the OS, choose “USB.” If you’re using a MIDI interface, choose “nid”, meaning MIDI.
4. Press the Globals button twice to exit.

Connect your computer to the Trigon-6 using either a USB cable or a MIDI interface.

If using USB, the Trigon-6 is a Class Compliant USB device. That means it does not require any additional drivers to be installed to communicate with your computer. It will appear in MIDI-OX and other MIDI applications as a MIDI port named “Trigon-6.” (Under Windows XP, it will appear as “USB Audio Device.”)

If using a MIDI interface, connect the computer’s MIDI out to the MIDI in of the Trigon-6. Depending on the type of interface, you may also need a MIDI cable.

Most MIDI interfaces or sound cards with built-in MIDI interfaces will work. However, we have received reports that Digidesign/Avid interfaces and Native Instruments Maschine may not transmit SysEx correctly for updates. The M-Audio Uno is an inexpensive, reliable, and widely available MIDI interface for use when updating our instruments.

To load and update the OS:

1. Run MIDI-OX.
2. From the Options menu, choose “Configure Buffers.”
3. Set the Low Level Output Buffers “Num” and “Size” to 1024.
4. Click OK to close the window and save the settings.
5. From the Options menu, choose “MIDI Devices.”
6. In the lower left quadrant of the window, select the MIDI port to which the instrument is connected. If connected via USB, choose “Trigon-6” (or “USB Audio Device” under Windows XP). If connected via MIDI, choose the MIDI interface. The selected MIDI port appears in the Port Mappings window.
7. Click OK to close the window and save the settings.
8. From the View menu, choose “SysEx.”
9. From the Command Window menu, choose “Load File.” Browse to and open the Trigon-6 OS update file.
10. From the Command Window menu, choose “Send SysEx.” The Trigon-6 displays a countdown indicating the progress of the SysEx file’s transfer. When the file transfer completes, a second, shorter countdown will start as the OS is written to memory. DO NOT power down. The unit will restart when the second countdown has completed.
11. The unit restarts itself after a successful update. The OS version is shown on the main display upon startup, after a “6” is displayed.

IMPORTANT NOTE

When the OS update is sent to the Trigon-6, do not shut down the Trigon-6. The Trigon-6 will automatically restart itself when the OS update is complete. During the update, two numeric countdowns occur on the main Trigon-6 display. The first begins at 999 and takes approximately 6-7 minutes to complete. This is the “loading phase.” After that, a second, shorter countdown occurs which begins at 8 and takes approximately 60 seconds. This is the “writing” phase of the update. DO NOT power down during this phase. The Trigon-6 will restart itself upon successful completion of the OS update. However, in some cases, the OS update may hang on “1” after the second countdown. If the Trigon-6 does not reboot automatically after the second countdown, wait 60 seconds and then power cycle.

Troubleshooting

• If the countdown stops before the file transfer is complete, turn the Trigon-6 off, then on, and try again. If this continues to happen, double the Low Level Output Buffers “Num” and “Size” values and re-send the SysEx file. If the countdown gets closer to zero, then you know your settings are moving in the right direction. If the countdown goes further from zero try reducing the “Num” and “Size” settings. You can also try doubling or quadrupling the “Size” setting. You may have to adjust the Low Level Output Buffers settings several times before finding the right combination.
• If “Status Byte Received In Data” is displayed, turn the Trigon-6 off, then on. This error means some other MIDI message the Trigon-6 was not expecting was sent through your MIDI interface. Make sure all other audio or MIDI or DAW software is closed, and no other MIDI devices are connected. If you continue to receive this message try restarting your computer and open MIDI-OX as your only application.
