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).

A progress bar shows exactly where you are inside each section so you always know what's coming. JUMP TO ANY SECTION Tap any section button to cue Ableton to jump there. Jumps respect Ableton's Launch Quantization so they always land on the beat - no awkward cuts, no off-time transitions. OBSERVER MODE - YOUR WHOLE TEAM, IN SYNC Every other musician can now open MD Buddy on their own iPad or iPhone and follow the set live - current section, progress, tempo - without touching anything. No vocal cues, no guessing when the bridge repeats or the outro's coming. A green border shows at a glance which device is actually in control, and Settings lists everyone currently connected by name. TRACK MIXER Toggle individual Ableton tracks on or off directly from the iPad. Want to drop the drums for a quieter moment or bring in extra instrumentation? Tap once. Mute presets save automatically per song and restore every time you navigate back to that song. AUTOMATIC SETUP MD Buddy finds the bridge app on your Mac automatically - no IP address, no manual configuration.
