The world’s first frequency-domain vocoder with multi-curve control and precision spectral fusion. Multi-Curve Spectral Vocoding MagicFusion is a multi-curve spectral vocoder workstation operating entirely in the frequency domain. Instead of relying on bandpass filters and envelope followers, it extracts the spectral characteristics of a modulator and applies them to a carrier, enabling precise, customizable vocoding across the entire spectrum. Apply independent fusion amounts per frequency or frequency range, then mix, modulate, and spread them to create anything from subtle vocal shading to extreme spectral transformations. Vocoder Signal Flow MagicFusion requires two audio inputs: the carrier (main input) and the modulator (sidechain). The plugin extracts the modulator’s spectral envelope and applies it to the carrier, creating a fused signal where both sources interact. This process provides clean, flexible control over the degree of spectral fusion and allows highly detailed shaping across the frequency spectrum. Dynamic Response & Formants Adjust the Smooth control to define how quickly the vocoder reacts, from fast, precise transitions to slower, more rounded movement. The Formant parameter shifts the spectral character of the modulator, while Detail adjusts the complexity of the filter response — from clean, intricate results to more organic, pumping behavior. MagicFusion 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).

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
