ddtctmcc "2D Touch Control To MIDI Control Change" This is a touch control app that is designed to work with touch gestures and output MIDI Control Change messages. This app is available as standalone version that can run in background and as an AUv3. It features basic features: - 2D Touch Area where you can set 3 MIDI values (X, Y and Touch On / Off) that will be sent as MIDI CC messages - Two gesture recording modes: "Loop" and "Once": -- In "Loop" mode the gesture is immediately repeated infinitely. You can restart it and change the direction of gesture loop -- In "Once" mode the gesture is recorded silently and only played back later when "trigger" or "+pause" buttons are pressed. ... and some important extras: - Scene support. You can store all settings in a "scene" and switch between them. There is an option to set a transition time between scenes to morph loops. - Extended timing support. Start/stop and speed of the loop can also be recorded and played back. The recorded gesture loop can follow the host tempo when running in plugin mode. - Layers. Each instance of the app supports multiple output settings; scene switch is synchronised across all layers.

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

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).
