  • Page 28: Oscillators

    Oscillators Oscillators provide the raw building blocks of the Prophet-5’s sound by producing waveforms, each of which has its own inherent sound charac- ter based on its harmonic content. The Prophet-5 has two oscillators per voice. Level controls for each of these are located in the Mixer section. Oscillator A is capable of simultaneously generating sawtooth and variable-width pulse waves.

  • Page 32: Mixer

    Mixer The Mixer section is where you set the levels of the various sound gen- erators on the Prophet-5. These include Oscillator A, Oscillator B, and the white noise generator. You must turn up at least one of these in order to make sound with the Prophet-5.

Switch to the Rev 1/2 filter by pressing the switch. 2. In the basic program, only Oscillator A is turned up in the Mixer. For a fuller sound, turn up Oscillator B in the Mixer, set its waveshape to sawtooth and detune it slightly by turning its knob to 2.

    This is useful for adding brightness to a sound as higher notes are played, which is typically how acoustic instruments behave.

  • Page 42: Low Frequency Oscillator

    Low Frequency Oscillator The LFO is a special-purpose oscillator that produces a frequency that is typically below the range of human hearing. The LFO is used for peri- odic modulation such as vibrato (periodic pitch modulation) filter modu- lation, and pulse-width modulation. The LFO can be routed to any or all of these destinations using the controls in the section.

    Pitch and Mod Wheels The Prophet-5 has a spring-loaded Pitch wheel and a Mod wheel. You can use these controls to enhance live performance by bending notes and adding modulation in real time as you play.

    The Release Switch switch affects the behavior of the Filter and Amplifier Enve- release lopes. The original Prophet-5 had a different way of handling Release from the more common method used today. If the switch is on, release knob setting on the Filter and Amplifier envelopes is used. If release switch is off, the Release on both envelopes is fast.
