72 Using USB Dave Smith Instruments
Using USB
The Pro 2’s USB 2.0 port enables bidirectional MIDI communication
with a computer. A MIDI interface and MIDI cables are not neces-
sary, just a USB cable. The Pro 2 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. The Pro 2 transmits and
receives MIDI data via USB, but does not transmit audio.
MIDI In and USB should not be used at the same time, as overlapping
messages from different sources may cause the Pro 2 to respond unpredictably. MIDI
Out and USB can be used at the same time and transmit the same data.
USB Notes
Under Mac OS X, “Pro 2 Keyboard” will appear as a MIDI port when
connected via USB and can be configured using the Mac’s Audio MIDI
Setup utility (typically found in Applications/Utilities).
Under Windows, the first time the Pro 2 is connected via USB, the
“Found new hardware” alert appears and it is automatically installed as
“Pro 2 Keyboard.”
In Windows, if you unplug the USB cable and plug it back in while a
program has the Pro 2 port open, you may have to resync. That usually
means going to the Pro 2 Keyboard Properties—in the Windows Device
Manager under “Sound, video, and game controllers”—and clicking OK.
If Pro 2 Keyboard is no longer listed in the Device Manager, power the
Pro 2 down and back up again while it is connected via USB. It should
be detected on power up.
