A MIDI sequencer that widens access to the compositional possibilities of novel tunings

A study was conducted to propose a new Dynamic Tonality MIDI sequencer, known as Hex. The new Dynamic Tonality MIDI sequencer aimed to make sequencing music in and across a large variety of novel tunings as simple as sequencing in twelve-tone equal temperament. It replaced the piano roll used in conventional MIDI sequencers with a two-dimensional lattice roll to enable the intuitive visualization and dynamic manipulation of tuning. The roll was compatible with the Dynamic Tonality line of software, which consisted of the microtonal synthesizers TransFormSynth, The Viking, and 2032. A button lattice was displayed in its own pane on the left side of the window in Hex, and horizontal lines were drawn from the center of each note to the right. These lines functioned as generalized note lanes similar to that in piano roll sequencers, with the added benefit that each note lane's height was always proportional to its pitch when the user changed the tuning.
