Retro Synth Analog oscillator in Logic Pro for iPad
The synthesizer oscillators are used to generate one or more waveforms. You set the basic tonal color with the chosen waveform or waveforms, adjust the pitch of the basic sound, and set the level relationships between oscillators. The signal of one or both oscillators is then sent to other parts of the synthesizer engine for shaping, processing, or manipulation. See filter controls, amp and effect controls, modulation, and global and controller settings.
Analog synthesizer sounds are typically attributed with having a warm and rich tone. You can create a wide variety of timbres using this synthesis method, notably string and pad sounds, synthetic brass, bass, and percussion.
Analog oscillator 1 and 2 parameters
Oscillator 1/2 Waveform buttons: Choose the type of waveform that each oscillator generates. The waveform is responsible for the basic tonal color. The oscillators output a number of standard waveforms—noise, sawtooth, square, and triangle.
Osc 1/2 PW knobs and fields: Adjust the pulse width (shape) of the square waveform when chosen for oscillator 1 or 2. This makes the square waveform more rectangular and nasal-sounding.
Semitone knob and field: Set the pitch of oscillator 2 in semitone steps, over a range of ±2 octaves.
Detune knob and field: Precisely adjust the frequency of oscillator 2 in cents (1 cent = 1/100th semitone).
Analog oscillator modulation and mix parameters
Shape Mod knob and field: Set the intensity of waveform shape modulation. The centered (off) position disables all waveform shape modulation with the LFO or filter envelope.
Left of center = LFO modulation.
Right of center = Filter Envelope modulation.
Vibrato Depth knob and field: Set the amount of vibrato (pitch modulation).
Oscillator Mix slider and field: Crossfade (set the level relationships) between the oscillators.
