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.

http://www.midiox.com/

To prepare the Pro 3 to receive system exclusive messages:

1. Press Global.
2. From the Global menu, select “MIDI Sysex Enable” and set it to “On.”
3. Next, select “MIDI Sysex Cable.”
4. If you’re using USB to update the OS, choose “USB.” If you’re using a MIDI interface, choose “MIDI.”
5. Press Global again to exit the Global menu.

Connect your computer to the Pro 3 using either a USB cable or a MIDI interface.

If using USB, the Pro 3 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 “Pro 3.” (Under Windows XP, it will appear as “USB Audio Device.”)

If using a MIDI interface, connect the computer’s MIDI OUT to the Pro 3’s MIDI IN. 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.

IMPORTANT

There are two parts to the OS 1.2 update — the Main OS and the Panel OS. Do not attempt to send both of these at the same time or you may “brick” (disable) your Pro 3. Instead, send the Main OS first, then, once it completes writing to the synth, restart the Pro 3. Then send the Panel OS, and once it completes writing, restart again.

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 “Pro 3” (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 Pro 3 OS update file.
10. From the Command Window menu, choose “Send SysEx.” The Pro 3 shows a numeric progress display indicating the progress of the SysEx file’s transfer. Follow any directions listed on the Pro 3’w screen before/after the numeric indicator completes. When the file transfer completes, “Do not Turn Off!” is displayed as the OS is written to memory. DO NOT power down while Pro 3 display shows this message.
11. When the installation completes, turn the Pro 3 off, then back on again. You can verify the installation by pressing Global. The installed OS version appears at the bottom right of the screen.

IMPORTANT NOTE

If the display goes dark when the update is sent to the Pro 3, do not shut down the Pro 3. The Pro 3 will automatically power off then back on when the OS update is complete. The update will take longer than the SysEx transmission displayed in MIDI-OX.

TROUBLESHOOTING

• If the numeric progress indicator stops before the file transfer is complete, turn the Pro 3 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 numeric progress continues, 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 Pro 3 off, then on. This error means some other MIDI message the Pro 3 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.

RESETTING THE GLOBAL PARAMETERS

You must reset the Global parameters of the Pro 3 after you update the OS.

• Press the Global button.
• Press Soft Button 4 to choose the Commands tab
• Use Soft Knob 1 to select Reset Globals, then press the Write button.
• Press Soft Button 1 to confirm.
• When finished, press the Global button again to exit the Global menu

CALIBRATING THE OSCILLATORS AND FILTERS

Please calibrate the oscillators and filters of the Pro 3 after you update the OS.

• Press the Global button.
• Press Soft Button 4 to choose the Commands tab
• Use Soft Knob 1 to select Calibrate VCOs & Filters, then press the Write button.
• The synthesizer performs its auto-calibration procedure. Don’t turn off the power while it’s doing this.
• When finished, the front panel controls return to normal and you can play the Pro 3 again.
• Press the Global button again to exit the Global menu
