Lyne is a modular sound synthesizer based on basic mathematical and bit manipulating operations. The idea for Lyne is based upon an article about algorithmic symphonies from one line of code.
Lyne has a GUI which lets you create an arithmetical graph which consists of one global counter node, constant and operator nodes. The graph is what makes up the synthesizer.

Lyne is written in Python. It makes use of the Tkinter library with the ttk extension. It also relies on ALSA by the time of writing this, which means that sound generation is only going to work on a Linux box with ALSA. It is known to run on Ubuntu.
