Nodal (software)


Nodal is a generative software application for composing music. The software was produced at the , , Australia. It uses a novel method for the notation and playing of MIDI based music. This method is based around the concept of a user-defined graph. The graph consists of nodes and edges. The composer interactively defines the graph, which is then traversed by any number of virtual players that play the musical events as they encounter them on the graph. The time taken by a player to travel from one node to another is based on the length of the edges that connect the nodes.

Supported Platforms and Versions

Early versions of Nodal were designed to run only on Mac OS X. As of version 1.1 beta, Nodal ran on Mac OS X 10.4, and Microsoft Windows operating systems. As of version 1.5, released in November 2009, the software became shareware in order to support its continued development. The current version is 1.9, released in October 2013 which runs on MacOS 10.6 and higher or Windows Vista, 7 and 8. This version has the ability to specify combinations of chords, sequences and randomised patterns within a single node and incorporates the use of scale modes. Nodal can be downloaded from the . It is also available from Apple's Mac App Store.

Working with Nodal

Nodal generates MIDI data as virtual players traverse a user-defined network in real-time. It can be used as a standalone composition tool, in conjunction with Digital audio workstation software, or played interactively in a real-time performance.
Nodal contains a built-in MIDI synthesiser and is also compatible with any hardware or software MIDI synthesiser, including all major Digital audio workstation software. Microsoft Windows versions can use the built-in Windows MIDI synthesiser. Nodal is also compatible with Apple's GarageBand software.

Prizes and awards

In 2012, Nodal was awarded the Eureka Prize for Innovation in Computer Science.
