geoMusica 1.200803

Finally, after 4 years of research and development, geoMusica software gets released, and on very special day, the Full Moon of August. I really hope this is the beginning of a wonderful process of sharing and growing with the community of fellow users and developers! Great days ahead for sure :

# **ABOUT:**

geoMusica is a tool to make music with geometry. Compose geometries and listen to the musical translation in realtime, perform and experiment with the Sacred Geometry inspired methods and be amazed by the beauty hidden within the Mathemagics. 

it is structured as a multi-layer composing tool, focused on geometrical parameters that can be set with special proportions and shapes, and should be used has a MIDI note generator, connected with your favorite electronic instruments to reproduce the musical output. Therefore, should be considered as a generative MIDI sequencer in terms of families of musical software, and its aimed at musicians that use electronic tools for creation. 

this project started as a personal research on Sacred Geometry studies, within the scope of the 3 year introdutory course that I attended led by Prof. Luis Elye, to the amazing field of knowledge hidden inside the Traditional geometrical legacy. with roots lost in time, this knowledge proved fundamental in bringing ordered geometrical shapes that generate meaningful musical correspondance, and revealing a hidden structural connection between geometry and music that becames obvious when exploring this tool.

as the research evolved, i've managed to do some outputs in form of talks and live concerts, that generated a surprising reaction on the interested audience, namely my fellow coleagues geometers, the TD artists community, and the Boom Festival community. that feedback gave meaning to the publication and release of this tool.

the aim for publication is to support the further development of this tool, either by other developers in the open-source spirit, or by anyone that use this tool and want to help supporting via the Patreon platform.

it is also a way of retribution to the fantastic TouchDesigner community, that along the years of using TD allways gave generously without asking for return.

# **DEDICATION:**

this public release of geoMusica is dedicated to my grandfather Francisco Alves Gato. I did'nt had the luck of meeting him personally, but I know that he, has many of us before and certainly after, was one of the humans that felt the sparkle of the search for Knowledge and Beauty, which led him to research on a special tuning for the Portuguese Guitar. I know we would had good times together playing with geoMusica!

# **INSTALL AND USAGE INSTRUCTIONS:**

this package contains the 4 processes of geoMusica:

## **geoMusicaEngine:** 
its the heart of geoMusica, where the geometrical shapes get converted into MIDI signal, and also frequencies and triggers for geoMusicaSynth. the Engine tries to run at 480 fps, so it matches the MIDI standard timming resolution. You should connect the Engine via MIDI to your favorite sound source, preferably a Polyphonic Aftertouch able synth so you can enjoy the full spectrum of frequencies that geoMusica generates. IMPORTANT: the Engine is hardwired to output each layer in a separate MIDI channel, so Layer 1 goes to MIDI Channel 1, and so on.

## **geoMusicaUI:**
the control center for the system, here you define all the parameters to generate the compositions, create presets with TDMorph (Darien Brito https://github.com/darienbrito) and synchronize with external systems.

## **geoMusicaRender:**
here the geometry gets visualized, in the most synthetical way possible, so you can focus on the musical composition. You can run the Engine without the Render if you want.

## **geoMusicaSynth:**
just a simple wavetable synth made from the "howtoaudio.toe" examples (Owen Kirby), to help people that do not know how to handle MIDI to experiment with geoMusica. the Synth is not essential for geoMusica, you can close it if you are using MIDI.

1. install Derivative TouchDesigner 2020.25380 
(https://derivative.ca/download/archive)

2. allow firewall access to TouchDesigner on both 
private and public networks (if asked)

3. run "geoMusica.2020.25380.bat"

4. wait for the 4 processes to open

5. on geoMusicaEngine, under "settings" page, select your MIDI Out Port. If you don't have a virtual midi loopback utility, I recommend loopMIDI by Tobias Erichsen (http://www.tobias-erichsen.de/) for localhost usage, and rtpMIDI for remote usage.

# **LICENSING:**

Since we are artists/programmers and not lawyers, I trust you will give credit where credit is due and respect the licence: 

GNU General Public License v3 (GPL-3) 

This means that if at some point you would like to use this tool in a commercial endeavour or you do not want to disclose the source code you will get in touch first, so a fair arrangement can be made.

# **AKNOWLEDGEMENTS:**

geoMusica has benefit from the incredible work of Darien Brito with TDMorph, that allowed for a seamless integration of a preset system that is at the same timea parametric generative tool by itself, expanding the possibilities of geoMusica greatly.

geoMusicaSynth is based on the very much helpfulTD community asset from Owen Kirby, clarifying the correct way to do audio in TD, "howtoaudio.toe".
