Async Sampler, a powerful musical instrument designed to bring your soundscapes to life. This flexible tool is dedicated to crafting captivating sound collages, dynamic asynchronous textures, rhythmic patterns, and rich sound designs. It opens up a world of creative possibilities, making it the perfect companion for music producers, sound designers, ambient, and noise enthusiasts. Whether you're a seasoned musician or a curious explorer, Async Sampler is here to inspire and elevate your musical journey. App comes with a rich library of unique samples, and you can easily upload and use your own sounds. Async Sampler fundamentally consists of three samplers that can reproduce sound asynchronously, meaning they can operate without being tied to a specific BPM, or synchronously, using an external MIDI clock source or the tempo of your project if you're using Async Sampler as an AUv3 plugin. The instrument features a versatile LFO that allows you to control any parameter. Async includes an effects processor and a master bus section. Also, you have the option to use external MIDI controllers, save and load your custom presets and samples, among other features. Key features: — Standalone and AUv3 versions — Three independent samplers — Extensive sample library out of the box — Ability to upload your own samples — Asynchronous and synchronous playback modes for each sample — Flexible LFO system that can control almost any parameter — Effects processor — Ability to save presets — And much more

About

GSDSP Quantum Distortion

  • 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).
