Unusable Engineering Releases Quadrant Modulator - Four-Quadrant Multiplier and Ring-modulation Effect (VST3 & AU)

The useful part

Unusable Engineering has released Quadrant Modulator, a four-quadrant multiplier and ring-modulation effect for macOS and Windows. The incoming audio is multiplied by a drawable Bézier/Node waveform, allowing the same oscillator to be used for four-quadrant modulation, amplitude modulation and one-shot amplitude shaping. An 8-slot sequencer stores waveform geometry, oscillator rate, shape and overflow settings.

How it works

• Other features include Clean and diode-inspired multiplication modes, positive or inverted wet-signal feedback, Clip/Fold waveform processing and tube-style output limiting.
• Rates can be host synchronized or quantized to a selected note set, with MTS-ESP support for microtonal tuning.
• Per-slot Rate Slew allows selected pitch transitions to slide while others change immediately.
• Though the core process is amplitude- and ring modulation, it is quite capable of a wide array of effects.

Details worth keeping

Pricing & Availability Quadrant Modulator is available for €29 (incl. 25% VAT) as an AU and VST3 effect plugin for macOS 12+ and Windows 10/11.
