PoiZone - Oscillators

Oscillators

Oscillators are the basic sound sources of a synthesizer, Poizone has 2 Oscillators (A and B) and one 'Noise' source. Oscillators A and B generate SAW or PULSE shapes that can be futher modified. All Oscillator modulations are applied to OSC A, so that OSC A is a carrier and OSC B is a modulator for RM and SYNC operations (as described below). OSC B always generates an unmodulated sound - for example, this is why OSC B has controls for pitch while OSC A does not. These features together with 'Unison' in the Master Controls section and the Effects Section allow Poizone to quickly and easily create thick, lush textures or cutting leads.

BALANCE

The knobs in the 'BALANCE' section are used to mix between Oscillator A, B and the Noise source.

  • OSC: Controls the balance between Oscillator A and Oscillator B, turn fully left to hear OSC A and fully right to hear OSC B, the 12 O?clock position is a 50% mix of OSC A and OSC B.
  • NOISE: The output of the OSC knob is then sent to the NOISE mixer, fully left is 100% Oscillators and 0% NOISE, fully right is 100% NOISE and 12 O?clock is a 50% mix of the Oscillators and the Noise source.

OSCILLATOR A

  • PW (Pulse Width): Controls the 'width' of the Oscillator waveform when the PULSE button is enabled and Oscillator is in PULSE mode. When fully left and the original waveform will be a narrow 'spike' shape, when fully right the waveform will be equal to the original PULSE waveform (100% width).
  • PULSE: Pulse switches between Saw and Pulse shapes of the Oscillator.
  • RING (Ring Modulation): Ring modulation multiplies the output of OSC A and OSC B. The result is passed to OSC A (e.g. A = A * B) while OSC B remains unchanged (has its original sound). Ring can be used to produce extra harmonics that are characteristic of struck metal.
  • SYNC: When selected synchronizes the phase of OSC A to B. In other words, every time OSC B completes its cycle OSC A is forced to reset and start its cycle from the beginning.

OSCILLATOR B

  • PW (Pulse Width): Controls the 'width' of the Oscillator waveform when the PULSE button is enabled and Oscillator is in PULSE mode. When fully left and the original waveform will be a narrow 'spike' shape, when fully right the waveform will be equal to the original PULSE waveform (100% width).
  • PULSE: Pulse switches between Saw and Pulse shapes of the Oscillator.
  • PITCH: Changes the pitch of OSC B by +/- 24 Semitones.
  • DETUNE: Changes the pitch of OSC B by 0 to + 50 Cents.
