How do I configure the OMS for my Quattro?

Go to the Control Panel or Chooser under the Apple Menu, and make sure AppleTalk
is turned off (this is recommended, although OMS will sense that it is on and prompt
you to turn it off). If you are installing your QUATTRO driver and configuring OMS
for the first time, follow these instructions to configure OMS.
First Time OMS Configuration Instructions:

1. In the Opcode folder, which you will find on your hard drive, locate the OMS
Applications folder, then OMS Setup. Double-click on OMS Setup.

2. OMS will inform you that it has not yet been configured. Click OK.

3. The “Create A New Studio Setup” dialog box now appears. Click OK.

4. The “OMS Driver Search” box asks you to choose the port on which you’ve
attached the QUATTRO (either Modem or Printer). DO NOT choose a port,
just click “Search.” OMS begins Searching. IMPORTANT: If the USB cable is
not correctly hooked up to the QUATTRO, setup will fail.

5. “OMS Driver Setup” shows the QUATTRO in a list when OMS successfully
finds the driver. Click OK. OMS will now define (shows “Identifying”) the
QUATTRO output port.

6. The “OMS MIDI Device Setup” dialog box will appear showing the
QUATTRO’s available output port with an open check box to the left of the
port. You will have to check this open box at this time to enable the output
port. Now click on OK.

7. Next, the “My Studio Setup” appears with a file save dialog box over it. You
will now need to name and save your new Studio Setup (or use the default
name) before you can assign various instruments to the QUATTRO’s output
and input. Assign your instrument (optional) and you are done.

8. Your QUATTRO is ready for use with MIDI.

You can run the OMS ‘Test Studio’ utility by going to the ‘Studio’ menu and
releasing the mouse on “Test Studio”. Playing a note on your keyboard will give
you an audio message from your computer, “MIDI received,” while the arrow
pointing to the keyboard icon flashes. Clicking on a keyboard icon with the
mouse pointer will send a tone cluster to the QUATTRO MIDI output port. The
LED will light, and your sound module should play the chord.
You may now exit OMS Setup by quitting the application. The rest is up to
configuration within your music software. Generally, this means selecting “OMS
Compatibility,” or “Open Music System” for your MIDI system setup.
