Oscillators
Oscillators provide the raw building blocks of the Prophet-10’s sound by
producing waveforms, each of which has its own inherent sound charac-
ter based on its harmonic content. The Prophet-10 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. Oscillator B is capable of simultaneously
generating sawtooth, triangle, and variable-width pulse waves.
The oscillators on the Prophet-10 are very stable. To emulate the random
pitch drift and oscillator instability of vintage instruments, use the vintage knob to add
randomness to the behavior of the VCOs, envelopes, LFOs, and lters.
The Oscillators section
Oscillator A can be hard-synced to Oscillator B for complex, harmoni-
cally-rich sounds when modulated.
Oscillator B features a fine knob for detuning and thickening sounds,
a lo freq switch that allows it to function as an LFO for modulation
purposes, and a keyboard switch that disables keyboard control over its
pitch (useful when used as an LFO, or for drones and other effects).
