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.
Stereo Delay
This audio unit plugin creates natural-sounding stereo delays with unique panning that expands stereo width without sounding repetitive. It features filters and a mixing matrix for dynamic echo placement, ideal for adding depth to music.
- Unique stereo panning matrix
- Natural, moving stereo echo
- Low-cut and hi-cut filters
- Feedback control
- LFO controlled pan
- Requires host app

Blue Mangoo Stereo Delay is designed to be the go-to app a for simple, musically tasteful delay effect. The most unique feature is the way it handles panning of delayed echoes in the stereo field. Most stereo delays set different delay times for the left and right channels, resulting in the famous ping-pong effect. The problem with the ping-pong stereo delay sound is that it's too extreme, and our ears quickly tire of hearing the same pattern of left-then-right delay repeated hundreds of times. This plugin does it differently. Instead of setting delay taps at different times panned hard left or right, it always keeps the same delay time setting for both the left and right channels, but it has a unique mixing matrix controlling the feedback between the left and right channels so that each time the echo repeats, it appears in a new place in the stereo field. This is different from a simple panning delay, because older echoes and newer ones can simultaneously appear at different positions in the stereo field. The result is a very natural stereo echo that expands the stereo width of the sound but doesn't sound repetitive or electronic. It's constantly moving and changing. The wet signal output has low-cut and hi-cut filters. The hi-cut filter tones down the harshness of the delay and makes it sound like natural echoes. The low-cut is especially useful for applying delay without making things sound muddy. At extreme settings the low cut can achieve a lo-fi telephone like delay sound. The signal flow diagram is as follows: Filters => LFO controlled pan => Stereo Delay Lines => Mixing matrix => Feedback to Delay Lines The dry signal (not shown above) bypasses the entire effect. The key difference between this and other delays is the mixing matrix, which is similar to the ones used in feedback delay network reverb effects to mix between multi-channel delays without changing the volume of the sound. It is the matrix (not the LFO) that creates the illusion that the signal has moved to a different location in the stereo field each time it repeats through the delays. *** THIS IS AN AUDIO UNIT ONLY EFFECT. IT REQUIRES A HOST APP SUCH AS AUM, Audiobus, GarageBand, OR Cubasis. IT DOES NOT RUN AS A STANDALONE APP. ***
