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.

Do we need yet another Delay? Of course! We need thousands of delays working in parallel with full spectral control. One Curve. Infinite Delays. MagicDelay lets you control thousands of spectral delays with a single, elegant curve. Apply BPM-type grids to lock your shapes perfectly to the tempo, or let them flow freely for more experimental motion. With the powerful Curve Modifier, you can modulate, morph, and reshape your delay patterns in real time — turning one curve into endless rhythmic and spectral variations. Thoughtful Feedback control Control your delay tails using either traditional feedback in percent or our unique dB-per-second decay system — created specifically to manage the feedback of many varying delay times at once. Using dB/s ensures predictable, consistent tail lengths across the entire spectrum, even in the most complex settings. Sculpt the Spectrum Refine your delays with built-in highpass and lowpass filters, adding warmth, clarity, or sparkle exactly where needed. Activate Crossfeed to expand your stereo image and create immersive, wide-angle motion. And when things get wild, use Kill to instantly mute and clear the delay line — total control at any moment. Beyond 100% Need more? Push into new sonic territory with Feedback Over, allowing feedback values beyond the traditional 100% limit. From endless atmospheric swells to self-oscillating spectral chaos, MagicDelay gives you room to explore — and break — the rules. A New Dimension of Delay Whether you’re a musician, sound designer, or producer, MagicDelay is a spectral playground built for discovery. Its multi-curve design, deep modulation system, and flexible feedback architecture make it a truly expressive tool for shaping delays far beyond the ordinary. MagicDelay 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).
