Prophet-6 Operation Manual

Oscillators

7 . Stereo/Mono:

Ste

Mon

(Stereo, Mono)—

The Prophet-6 defaults to

stereo operation. When set to Mono, this parameter defeats all pan settings

and modulation, effectively making each of the outputs a mono output.

8 . Pgm Dump:

Prg

Ten

Ban

usr

All

(

Program, Tens, Bank, User

Banks, All)—

Transmits the current program, ten programs from the

currently selected bank and tens location, the current bank, all user

banks (0-4), or all banks (both user and factory) in SysEx format via the

selected MIDI port. (See: “MIDI Sysex.”) Dumped programs will load

back into the same bank and program location in memory when received by

the Prophet-6 via MIDI.

Oscillators

Oscillators provide the raw building blocks of the Prophet-6’s sound by

producing

waveforms

, each of which has its own inherent sound charac-

ter based on its harmonic content. The Prophet-6 has two oscillators, plus

a sub oscillator and a noise generator per voice. Level controls for each

of these are located in the Mixer section.

Each oscillator is capable of generating triangle, sawtooth, and variable-

width pulse waves. These waveshapes are continuously variable and

smoothly transition from one shape to the next as you turn the

shape

knob. This provides a variety of “in-between” waveshapes.

The oscillators on the Prophet-6 are extremely stable. To emulate the random

pitch drift and oscillator instability of vintage instruments, use the

slop

parameter to

dial in as little or as much drift as you like.
