Musical Study with Isomorphic Computer Keyboard, August 16, 2017 This is the first work of the keyboard-related cycle, and it is not microtonal, however, it contains some theoretical introduction applicable to other works, which are essentially microtonal

GitHub repository

GitHub Web site of the project

All applications presented by this project can be played live using a Web browser. They are based on the Web Audio API and common platform developed by the author. Alternatively, the project can be downloaded from GitHub to execute the applications locally, in this case, Internet or any other network is not required.

The applications support standard touchscreen. With a touchscreen, one can play with ten fingers, any chords, glissando (important) in any combinations. So a touchscreen is highly recommended. Without a touch screen, a user still can play with a mouse/touchpad and, in special cases, a computer keyboard.

Browsers based on V8 engine are recommended, such as Chromium, Chrome, Opera, Vivaldi, Microsoft Edge v. 80.0.361.111 or later, and more…

Live Play Applications

Sound Builder In addition to this Web browser-based application, there is the additional tool, Fourier.WaveFFT; it requires a one-click build (.NET Core). It can take an audio sound sample, Fourier-transform it, and embed the result in an instrument file to be open by SoundBuilder for the synthesis. The user can design one's own instrument synthesizer and embed it in all musical instruments of the system listed below.

Microtonal Chromatic Lattice (keyboard instrument)

Specialized 29-EDO Keyboards

Application for comparison of tonal systems

Sequence Tool

Experimental: Microtonal Playground

Live play: Microtonal Playground

This is a new experimental application under development.

It allows anyone to define one's own frequencies, place them in a simple rectangular-grid keyboard and play with ten fingers on a touchscreen, or at least with a mouse/touchpad. For the customization, the live play won't be enough, it shows some demo, presently based on the scales presented by Dawson Berry. Presently, you need to download the entire product and modify the file “user.data”. The definition mechanism is very flexible: the frequencies can be defined as fixed values or as rational-number intervals relative to the specified base tone, the labels can be customized, automatic repetition of tones with octave transposition is available.

Later, the application will get standard controls of volume, sustain, transposition, and the Recorder. Right now, only the choice of instrument is available.

Also under development: the tonal system put forward by Kite Giedraitis, with this layout and generator system. I already make it playable, but I'm trying to design something to be practically playable.
