Philicorda is a faithful emulation of the legendary 1960s Philicorda organ. This plugin replicates the transistor-based sound of the later GM751 models, delivering the distinctively warm yet clear tones that made the Philicorda a classic. Like the original hardware, Philicorda features a vibrato circuit, a spring reverb, and two speakers. We have also added some extra features: overdrive, envelope generator, leakage, bias, and key click. Available as AUv3 and Standalone.

About

GSDSP Quantum Distortion

Explore four distinct distortion effects—Saturation, BitCrush, Ring Modulation, and Downsampling—blended and controlled via an intuitive XY pad. Shape harmonics, reduce digital resolution, introduce inharmonic motion, and create classic digital degradation for unique audio textures.

Highlights
  • Four distortion algorithms (Saturation, BitCrush, Ring Modulation, Downsampling)
  • Intuitive XY pad for blending effects
  • Custom waveshaping saturation
  • BitWarp for tonal variation
  • Tunable oscillator for ring modulation
  • Adjustable downsampling rate and jitter
  • AUv3 audio effect plugin
Features
Read full description

Four complementary distortion algorithms — Saturation, BitCrush, Ring Modulation, and Downsampling — blended and shaped through an intuitive XY pad. Saturation Shape harmonics using Quantum Distortion’s custom waveshaping saturation. Adjust Drive to set the intensity from subtle warmth to strong coloration, and use Asymmetry to introduce controlled even-harmonic emphasis of vintage tube characteristics. BitCrush Reduce digital resolution using BitCrush and reshape the crushed signal with BitWarp, which bends the quantization curve for additional tonal variation. This combination allows precise control over both the amount of reduction and the character of the resulting digital artifacts. Ring Modulation Introduce inharmonic motion using ring modulation, generated by multiplying the input with a tunable oscillator. Adjust frequency and amount in real time to create anything from light metallic shading to dense, shifting sidebands. Downsampling Lower the sample rate using Downsampling, reducing temporal resolution for classic digital degradation effects. Set the rate down to 200 Hz or introduce Jitter for controlled randomness, adding instability and movement to the downsampled signal. XY Pad Blending Navigate between the four distortion algorithms using the XY pad, allowing smooth transitions or static blends across the processing modes. The background updates to reflect the current region, providing clear visual feedback while exploring hybrid distortion shapes and interactions. Quantum Distortion is an AUv3 audio effect plugin compatible with Logic Pro, AUM, Cubasis, GarageBand and many more. A Desktop version is also available for Windows and macOS (VST3 / AU / AAX).
