Lyne is a modular sound synthesizer.


There are downstream depedencies that have to be fullfilled in order to install Lyne. On a Ubuntu box for example, you need to install the packages python-tk and libasound2-dev as well as the Python header files through:

sudo apt-get install python-tk libasound2-dev python-dev

You then should be able to install Lyne through

sudo python setup.py install


After successful installation you should be able to run Lyne from the command line via


Then, the Lyne application window should pop up. You start with an empty canvas.

First steps

In Lyne, you basically build an arithmetic graph which consists of three types of nodes and connections in between. First, place a "Counter" node on the canvas by clicking the "Counter" button in the toolbar and then double-click somewhere on the canvas. You can have at most one "Counter" node and you need at least one to generate sound.

Next, you can place any arbitrary number of "Constant" and "Operator" nodes. To connect two nodes, you click on the orange colored area of the source node which summons an arrow originating in the source node and which follows the mouse cursor. Next, move to the sink node and click in its orange colored area. The nodes should then be connected.

Note: The "Counter" and "Constant" nodes have only outputs, which means you can not use them as sink nodes. Only "Operator" nodes have inputs and can therefore be used as sink nodes.

Each node has a speaker icon. Clicking on that icon will mark the corresponding node "active". It will also start sound generation. For this, the graph you just build is evaulated at that node and the number stream that results there is piped into a PCM device.
