Jeff Holtzkener released Concentric Rhythm, a totally free new way to explore musical patterns with geometric transformations in concentric circles. It sounds like fun, but requires iOS 10. Thanks to reader Chris for the heads-up on this one.
Concentric Rhythm iTunes Description:
Concentric Rhythm is an interactive tool for generating, developing, and combining musical patterns. It uses geometric transformations and many other simple processes to create, develop, and evolve music. It provides a unique way to look at and explore musical ideas.
The looping musical timeline is visualized as a circle, which allows you to treat musical patterns as concentric shapes. This makes performing geometric transformations such as rotations, reflections and folding very natural and intuitive.
It also provides tools for melodic lines such as random-walk generation and scale-based inversion and transposition.
You can generate rhythmic lines using cross-rhythms or the Euclidean algorithm, and allows for great visualisations of complex polyrhythms.
Concentric Rhythm was originally developed as a new way to improvise electronic music, but it is also a great tool experimenting with and developing musical material, or just for casually playing with music in a unique, hands-on, way.
Many of the ideas here were inspired by the book ‘The Geometry of Musical Rhythm’ and this app is a powerful tool for anyone who is interested in exploring these ideas. But at the same time is easy enough to use that anyone (even with no musical or mathematical background) can make interesting musical patterns and think about the musical world a little differently.
Developer Jeff has even provided a detailed, and well recorded, tutorial video for the free app!
DA ONE Synth is a powerful, but ugly, modular synthesizer that lets you combine subtractive, additive, wavetable, vector, and FM synthesis! All with Audiobus and MIDI! Thanks to reader yactre for the tip on this!
DA ONE Synth iTunes Description:
The DA ONE synthesizer app provides you with a powerful synthesis engine combining digital and (virtual) analog synthesis methods, such as wavetable synthesis, vector waveform mixing, subtractive, additive, and frequency modulation synthesis. The individual blocks of this synthesizer are connected using an innovative and highly flexible routing system that allows millions of different configurations of oscillators, filters, and distortion blocks.
Doug Woods did a timely demo for this one! It certainly sounds unique in the provided presets.
