ChordWeaver is a music composition app based on 5-part modern harmony extensively used in symphonic scores, cinematic soundtracks, jazz chord changes and contemporary songwriting. ChordWeaver offers 3636 chord resolutions/combinations and 10 instrument or ensembles with 1920 sound files. The techniques used include altered chords (or unresolved appoggiaturas), parallel ninths, giant steps, tritone substitutions, bi-tonal ambiguities as well as traditional chord progressions. For some composers ChordWeaver will provide a fast, easy way to work with modern harmony. For other composers it offers a whole new world of possibilities and variations on traditional progressions. For the seasoned pro, it is a huge time saver. Here is how ChordWeaver efficiently guides you through the composition process. You choose your starting chord, and ChordWeaver instantly shows you and lets you listen to multiple resolutions to that chord, traditional ones and more creative, unusual ones. With each subsequent chord choice, the process is repeated. ChordWeaver seamlessly guides you to multiple possible chord options (some you will be familiar with and others you will not have considered), lets you listen to your work in progress, offers the option to transpose up or down and allows you to save your final product as a .chords file or .mid file and export or share it. You can also mirror ChordWeaver on your main system, play back the audio and improvise on your favorite instrument. Likewise, you could import the MIDI file into your sequencer and play back the harmonies using your preferred sample libraries. These chord options in ChordWeaver are the result of decades of studying the scores of the masters in various genres. They reflect the actual use of these chord progressions and resolutions by these composers and are not simply based on purely theoretical considerations.

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).
