Sound Writer is a 3D virtual music box, which can be played with easy finger gestures. Simply rotate the sphere in the middle of the screen by dragging it with your finger. When the pins on the surface of the sphere hit the "tone comb", sound will be played. You can also change the sound color and the layout of the pins by two finger gestures.

Read full description

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).
