Vector synth is an example of a few things :

• A melody line generation tool which lets you plot the pitch, volume and 'generic waveform sound'. This means you can essentially hear a piece of music, grab and plot the synth. waveform and generate your own melody lines using this synth. Whether the synth be a persons voice, waveform or whatever ! This is accomplished by merging a FM (frequency modulator) and a Vector Graphics application (XFig).
• Rapid prototyping using a vector graphics application as the front end and a custom engine as the back end.

This is a project foundation for C++ and WASM. The output from the C++ are ES6 WASM modules for nodejs and the browser (loaded through an example webcomonent). You can test the output for this pacakge using npm : https://www.npmjs.com/package/vector-synth

A test executable : VectorSynthTestNodeTest.js

Open a new terminal, then :

cd webcomponent

npm i

polymer serve # or user a different serving mechanism if you don't have polymer

./autogen.sh

If you are building Web Assembly :

source /usr/local/emsdk/emsdk_env.sh

./configure

emconfigure ./configure

make

emmake make

emmake make install
