According to the company, implementing frequency modulation synthesis completely from scratch in firmware, the Quad Operator is able to provide a modern take on frequency modulation synthesis.

Main Features:
- 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
Price and Availability
The Quad Operator will retail for $500. Humble Audio also announced the availability of the Algo expander ($85) for the Quad Operator, which provides the following extra features:
- Saving and loading of modulation send knob positions for FM algorithm design reuse
- Crossfade between pairs of saved algorithms, or a saved algorithm and the live knob positions
