58 Using USB

Using USB
The Prophet-6’s USB 2.0 port enables bidirectional MIDI communica-
tion with a computer. A MIDI interface and MIDI cables are not neces-
sary, just a USB cable. The Prophet-6 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 Prophet-6 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 Prophet-6 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, “Prophet-6 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 Prophet-6 is connected via USB, the
“Found new hardware” alert appears and it is automatically installed as
“Prophet-6 Keyboard.”
In Windows, if you unplug the USB cable and plug it back in while a
program has the Prophet-6 port open, you may have to resync. That
usually means going to the Prophet-6 Keyboard Properties — in the
Windows Device Manager under “Sound, video, and game controllers”
— and clicking OK. If
Prophet-6 Keyboard
is no longer listed in the
Device Manager, power the Prophet-6 down and back up again while it
is connected via USB. It should be detected on power up.
