Turn any sound into lush pads, frozen textures, or drifting spectral motion with this multi-curve spectral blur and freeze effect. Frequency-Dependent Blur MagicBlur is a multi-curve spectral blur and freeze processor designed for transforming audio into pads, overtone glissandi, reversed textures, and glitch-like movements. Apply separate blur times per frequency or frequency range, then mix, modulate, and spread them to explore anything from subtle, washed-out ambience to extreme spectral experimentation. How Spectral Blur Works Incoming audio is analyzed into fast-moving spectral frames, each representing the frequency content of a small slice of sound. Instead of playing every frame in sequence, MagicBlur lets you pick frames at defined intervals and morph smoothly toward the next one. The Blur Time sets how gradually frequencies transition — and because MagicBlur supports independent blur times per frequency, you can shape different parts of the spectrum with fine-grained control. Freeze, Reverse & Transform Disable morphing to create a spectral freeze, holding each frame until the next is selected. Reverse the morph direction, apply envelopes, or shift pitch to create evolving drones and unique spectral transitions. Combined with MagicBlur’s modulation system, these tools unlock a wide range of expressive and experimental sound design possibilities. MagicBlur 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).

WoodTroller is NOT an app to annoy people. It’s an MPE and midi V2 multi touch bar keyboard and midi controller : The MPE touch bar supports multiple notes with individual pitch shift (horizontal movement), pressure and cc74 (vertical movement). WoodTroller has 8 general purpose rotary controls : - Each can send 6 different CC messages to different channels. - Each of the 6 command values can be mapped differently to the full rotary range. - So 1 rotary can control several parameters on the same or on different instruments. - Rotary names, colour, unit, range can all be user set. WoodTroller also has 8 general purpose on-off or push buttons : - Each button can send up to 8 different midi commands (CC, PC, NoteOn, …) to different channels. - This allows to quickly switch multiple midi instruments or devices to another program or to other settings. - Each midi command’s data value can be auto incremented/decremented. - All button names, colour, type can be user set. All settings can be stored in presets in iCloud which yield automatic preset syncing between several WoodTrollers on different devices. WoodTroller is available as stand-alone app and as AUv3 plugin.
