Who said FM synthesis has to be complicated? Humble Audio got in touch with us to announce the immediate availability of Quad Operator, a new, hands-on Eurorack module with 4 Variable Waveshape Operators for Linear FM Synthesis.
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.
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
