[ACCOLADES] - Featured in Apple's staff favorites! - Reviewed in Computer Music magazine and received a 9/10! [DESCRIPTION] Jasuto is the worlds first (and most powerful) modular synthesizer for the iDevices. Jasuto allows you to visually construct your own synths/effects, and use them to make sequences all on your device! With the addition of a fully-featured sampler you can now record/resample/edit, and even create entirely new samples by drawing right in the app. Jasuto uses the relative position of nodes and their connections to control the sound. So the scene not only represents the synthesis structure, but also a custom multi-touch control surface. Motion can be recorded per node giving you rich, flexible automation. Connections can be created automatically by simply dragging nodes around, or manually. Each wire can be double-tapped to allow even more control of each connection. Jasuto comes installed with 75+ modules as well as 200+ pre-loaded scenes and samples. Each of the modules have been hand-optimized for your device's CPU, allowing you to create extremely complex scenes. [NOTABLE FEATURES] - Anti-aliased oscillators with hard-sync, FM, PWM, PM - Analog style filters (ap, lp, hp, bp, ladder emulation) - Signal control (compressor, limiter, gate, follower) - Zoomable sampler editor with several loop modes (normal, 1 shot, ping, granular) - ADSR envelope editor - Multipage/octave sequencer - Tape style analog delay - Reverb, phaser, several waveshapers - Resample/record the current playback - Audio copy via the pasteboard - Incoming OSC and MIDI for notes and CC's - Audiobus support (input, effect & output source) - Completely compatible with iOS7 - Updated UI graphics - Universal device and Retina support - A shiny new manual - Added background audio support - Low latency audio (256 samples) - Sample sharing through SoundCloud - Dropbox syncing of samples/scenes - High Fidelity (Hi-Fi) Audio [WEBSITE] http://www.jasuto.com

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).
