[. . . ] 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. 2. 3. 5. 10 11 Hooking up your USB Audio Quattro The Quattro provides four line inputs and four line outputs, and will accept a +4dB balanced signal on 1/4" TRS plugs (tip-ring-sleeve), or a -10dB unbalanced signal on 1/4" TS plugs (tip-sleeve). Each 1/4" jack will accept either TRS or TS 1/4" plugs. You may connect the output of a line level instrument such as an electronic keyboard or instrument preamp, the output of a microphone preamp (a mic preamp is required for use with a microphone), or the output of a CD player or similar line-level device. Check your device's documentation for information on its operating line level (+4 balanced or -10 unbalanced), and see the section, "Using the Input Level and Output Level Switches" in this manual. You may connect the four outputs of the USB Audio Quattro to a mixing console, or use two of the outputs for a stereo send to a monitoring system (power amp and speakers, or a home stereo), powered speakers, or a headphone amplifier. Again, check your device's documentation for information on its operating line level, and see the section, "Using the Input and Output Level Switches. " The diagrams below illustrate those scenarios. Typical Setup #1 shows the USB Audio Quattro with a mic/instrument preamp plugged into Inputs 1/2 (we suggest the DMP3 Preamp by M-Audio), and a MIDI sound module's audio outputs plugged into Inputs 3/4. The four outputs of the Quattro are plugged into a mixing board. Typical Setup #2 shows a CD player plugged into Inputs 1/2, and Outputs 1/2 plugged into a monitoring system. MIDI Operation The Quattro provides one (1) MIDI input and one (1) MIDI output. MIDI operation on the Quattro is independent of the audio operation, and therefore must be configured separately. When you install the drivers for the Quattro, the MIDI drivers will also install automatically, and will enable them for use in Windows, ready for MIDI setup within your music program. On the Mac, the OMS MIDI Manager from Opcode is required, and must be installed prior to installation of the Quattro drivers. Please refer to the Macintosh installation procedure earlier in the manual for information on configuring the Quattro MIDI driver in OMS. Your music software has a MIDI device setup page. Open that page, and click on the USB Audio Quattro "MIDI In" and "MIDI Out" devices to select and enable them. On the Macintosh, if OMS is configured properly, you will be able to select OMS for MIDI input and output. As stated, the Quattro can be your only MIDI device, or it can be used in conjunction with as many other MIDI devices in your system as your music program allows. [. . . ] Possible Cause1: On the PC, if you are using the ASIO drivers, and ASIO is selected in the USB Audio Configuration Manager, then you will not be able to hear you system sounds (using the MME drivers) if they are being directed to the Quattro. If you have another sound device in your system, you can go to Control Panel | Multimedia and select this other device. Then you will hear system sounds, provided you are monitoring the alternate sound device in some fashion. Possible Cause2: On the Mac, you must restart once after installing the USB Audio Quattro drivers. [. . . ]
