Quadrant Modulator gives Unusable Engineering a very hands-on modulation plugin. Audio gets multiplied against a Bézier or Node shape drawn by the user, turning one visual oscillator into ring modulation, amplitude modulation, or single-cycle level shaping. That oscillator can free-run, track input pitch through a phase-locked loop, or fire once from a trigger.
Things get deeper with eight sequencer slots for waveform geometry, rate, shape, and overflow data. Tempo sync sits beside note-set quantization, MTS-ESP handles microtonal tuning, and Rate Slew lets certain pitch moves glide while other slot changes happen instantly. Pretty flexible for such a focused setup.
Processing choices cover Clean and diode-style multiplication, normal or inverted feedback on the wet path, Clip or Fold treatment, and tube-flavored output limiting. Quadrant Modulator costs €29 with 25% VAT built in. Mac users get AU and VST3 on macOS 12 or later, while Windows 10 and 11 users get VST3.
