Prophet 12 Module Operation Manual

Overview

Overview

This is a brief overview of the Prophet 12 module, describing its capabilities and

its operation. More in-depth information about specific parameters can be found

in the reference section of the manual. However, don’t let a lack of familiarity

with either the instrument or sound synthesis prevent you from turning knobs

and pressing buttons—that’s what they’re there for! You won’t break anything

and you can always get back to where you started, even if you have no idea what

you’re doing. Great things can occur with synthesizers when you don’t quite

know what to expect, so start twiddling and keep your ears—and mind—open.

Getting Started

The Prophet 12 module is a twelve-voice, polyphonic synthesizer, which allows

up to twelve distinct notes to play simultaneously. We refer to the Prophet 12 as

a hybrid synthesizer. That is, it uses a combination of digital and analog audio

electronics to generate its sounds, called programs.

The Prophet 12 contains 792 programs organized into eight banks of 99. Half the

programs are in four Factory banks and the rest are in four User banks. When a

Prophet 12 leaves the factory, the User banks are an exact copy of the Factory

banks. Program 1 in bank 1 of the User banks is the same as program 1 in bank

1 of the Factory banks, User program 2 is the same as Factory program 2, and so

on. All programs in either the Factory or User banks can be edited using the front

panel controls, but the edits cannot be saved to the Factory banks, only the User

banks. The Factory banks are read-only, permanent.

Choosing programs is simple. Use the B

ank

S

elect

knob to choose User banks

(U1, U2, U3, U4), or Factory banks (F1, F2, F3, F4), and then use the P

rogram

S

elect

knob to select program number, 01 through 99.

While auditioning programs, it should become obvious that some programs are

split—two different sounds can be played from different zones of the keyboard—

and some are stacked—one sound is layered on another. The Prophet 12 is

bi-timbral. That is, it can play two different sounds simultaneously and each

of those sounds can be routed to its own stereo outputs, if desired. Each of the

Prophet 12’s program memory locations is capable of saving and recalling two

different programmed sounds, one in layer A and one in layer B. Layers are used

to facilitate split and stacked programs.
