4 Variable Waveshape Operators for Linear FM Synthesis Implementing frequency modulation synthesis completely from scratch in firmware, the Quad Operator is able to provide a modern take on frequency modulation synthesis. One knob per function design for true ease of use Any FM algorithm is possible via modulation matrix The Algo expander provides algorithm save/recall and crossfading capabilities Independent output per operator Virtual VCA per operator for both animating modulation and output volume control Includes a dedicated “AR FM” input with its own modulation sends, designed to bring an audio rate signal in from your rack for use as a modulator. Try processing a phase locked operator, and feeding it back in! Each operator can also be unlocked then tuned and patched independently, making the module a great general purpose oscillator bank Convincing digital emulation of classic analog waveshapes—sine, triangle, square, and saw An LFO mode, enabled the generation of phase locked, complex modulation signals
