- Oscillator 2 Advance Modulation Functions.
Quad-2 has several modulation types that allow Oscillator 1 to influence Oscillator 2, and vice versa; the type and parameters of these parts can be adjusted 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 |
Additionally, there is a 'String' model available with 'Length' and 'Damping' control. - Phase Distortion and WaveShaper in each Oscillator with:
Amount control
X control
Y control
XY field
