Set Module: The Set Module enables musicians to explore harmonic structures and scales of all kinds, and discover new ways of organizing pitch material. Built on the principles of pitch set theory, it offers an intuitive interface along with a rich set of practical tools. Features include fixed superset, fixed subset, invariance calculation, interval vector constraints, unfolding, and numeric recombination mode. The module is designed to make working with complex musical ideas easier and more intuitive, and can be used in songwriting, arranging, film scoring, and concert music composition. Tempo Module: The Tempo Module allows users to set a range for rhythmic units and define a tolerance for timing variations. It supports a system where up to six different tempos can be freely switched and converted. Tuning Module: Start at 1/1 and craft your own tuning system with cents or ratios. Map it onto a standard keyboard so you can transpose in 12ET or in precise cent steps. Hear your microtonal scales live, then export .scl and .tun files straight to your DAW—unlocking boundless realms beyond the twelve-tone limit. New Euclid and Orbit modules added! Detailed guide will be updated shortly.
