Oscillator On/Off
Waveforms: sine, square, saw, triangle, noise, and pink noise, plus many other additive and spectral waves.
Free Oscillator running On/Off
Track On/Off (keyboard tracking)
Octave up and down
Semi-tuning
Fine-tuning
Sub-oscillator with 2 waveforms (left from the center position adds a Sinus Waveform and right form the center position adds a Square Waveform)
Spread dial which turns the Oscillator in a multiple Oscillator sound with increased detuning between these Oscillators.
Volume

Sync Off / Hard / Soft (only Oscillator 2)
Oscillator 2 Modulation Functions.
Quad has a number of different modulation types that allow oscillator 1 to influence oscillator 2 and vice versa, the type and various parameters of these parts can be altered using the modulation type and amount 1 and 2 controls.
Types: Ring Modulation (Ring) | Phase Modulation (PM) | Frequency Modulation 1/2/3/4 (FM1/23) | Feed 1/2/3 | Sign | Mix | Cross | Skew | Filter Modulation | String |
Phase Distortion and WaveShaper in each Oscillator with:
Amount control
X control
Y control
XY field
Distortion Types: 2 Point | And | Cos1 | Cos2 | FM (Waveshaper only) | Feed | Fold | Fuzz | Gap | Hard | Oct1 | Oct 2 | Oct3 | PWM / PWM2 (WaveShaper only) | Rez1 | Rez2 | Saw | Shift1 / Shift2 (PhaseDistortion only) | Static | Trans
