12 Oscillators

Oscillators

The Prophet 12 has four oscillators for each of its twelve voices. The oscillators

are capable of generating the “classic” analog wave shapes—sine, triangle,

sawtooth, square—as well as more complex shapes and different types of noise.

Use the four oscillator buttons to select an oscilla

tor for editing. The arrows that connect the oscil-

lator buttons is a graphic representation showing

which oscillator affects another when the Sync, FM

(frequency modulation), or AM (amplitude modula-

tion) parameters are used. Oscillator 2 affects oscilla-

tor 1, oscillator 3 affects oscillator 2, and so on. For

information about what the Sync, FM, and AM param-

eters do, see the relevant items later in this section.

Tip: To edit a parameter on all oscillators simultaneously, press and briey

hold any of the oscillator select buttons until all of them are lit. Select the

desired parameter using Prev and next Param (Soft keys 2 & 3). Press and

hold, Hold: edit all (Soft key 1) while adjusting one of the soft knobs. Or

use the soft knobs to edit the same parameter for each oscillator individually.

Press any oscillator button to exit.

Shape/Noise: Off, Sawtooth, Pulse, Triangle, Sine, Tines, Mellow,

Church, Muted, Nasal, Boing, Gothic, Ahhh, Shrill, Ohhhh, Buzzzz, Meh,

Red Noise, White Noise, Violet Noise—

Used to select the wave shape or type

of noise generated by the selected oscillator. Wave shapes include four typical

analog synthesizer waves as well as twelve more complex wavetable sounds.

There are also three types of noise: red, white, and violet.

Shape Mod/Pulse Width: -64…0…63

—Causes the wave shape to be

altered. How it changes depends upon the selected shape. A setting of 0 is the

default, unaffected shape.

When Sawtooth is the selected shape,

SHaPe mod/PulSe WidtH controls the

symmetry of the wave, similar to pulse width on the Pulse wave creating the rich

sound of two sawtooth oscillators.
