Using USB

Resetting the Global Parameters

If you’re trying to track down a problem, it’s sometimes a good idea to

reset the Global parameters to their defaults. This is a quick way to make

sure that the Prophet Rev2 returns to its factory settings.

To reset all Global parameters to their default settings:

1. Press the

global

button.

2. Use the

parameter

knob to select

reset

globals

, then press

write

Using USB

The Prophet Rev2’s USB 2.0 port enables bidirectional MIDI commu-

nication with a computer. A MIDI interface and MIDI cables are not

necessary, just a USB cable. The Prophet Rev2 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

Rev2 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 Rev2 to respond unpredict-

ably. MIDI Out and USB can be used at the same time and transmit the same data.

USB Notes

Under Mac OS X, “Prophet Rev2 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 Rev2 is connected via USB,

the “Found new hardware” alert appears and it is automatically installed

as “Prophet Rev2 Keyboard.”

In Windows, if you unplug the USB cable and plug it back in while a

program has the Prophet Rev2 port open, you may have to resync. That

usually means going to the Prophet Rev2 Keyboard Properties — in the

Windows Device Manager under “Sound, video, and game controllers”

— and clicking OK. If

Prophet Rev2 Keyboard

is no longer listed in the

Device Manager, power the Prophet Rev2 down and back up again while

it is connected via USB. It should be detected on power up.
