Using USB
Mopho’s USB 2.0 port enables bidirectional MIDI communication with a
computer. A MIDI interface and MIDI cables are not necessary, just a USB
cable. Mopho is a Class Compliant USB device. That means it does not require
any additional drivers to be installed to communicate with a Mac or Windows
computer.
Mopho transmits and receives MIDI data via USB, but does not transmit audio.
Note: MIDI In and USB should not be used at the same time, as
overlapping messages from different sources may cause Mopho to
respond unpredictably. MIDI Out and USB can be used at the same time
and transmit the same data. Poly Chain Out is an independent MIDI bus
and can be used regardless of the “normal” MIDI connection.
USB Notes
Under Mac OS X, Mopho will appear as a MIDI port when connected via USB
and can be configured using the Mac’s Audio MIDI Setup application (typically
found in Applications/Utilities).
Under Windows XP, the first time Mopho is connected via USB, the “Found
new hardware” alert appears and Mopho is automatically installed—somewhat
misleadingly—as “USB Audio Device.” If there is already another Class
Compliant USB device installed, Mopho will show up as “USB Audio
Device(2)” (or 3 or 4 or...).
To determine which USB Audio Device is Mopho:
1. Open the System Control Panel
2. Click the Hardware tab.
3. Click Device Manager.
4. Expand “Sound, video, and game controllers.”
5. Right-click any “USB Audio Device” and choose Properties from the
pop-up menu.
The General tab of the USB Audio Device Properties window displays the
Device Type, Manufacturer, and Location. For Mopho, the Location should read
“Location n (DSI Mopho).”
