1. Make sure you have Processing, version 1.0 or higher, installed and working on your computer.

2. Download and decompress the archive.
1. Copy the "SoundCipher" folder to Processing's "libraries" directory.
On OS X this is ~/Documents/Processing/libraries and on Windows is My Documents/Processing/libraries.
If the libraries folder is not present, then create it.

2. Restart Processing.

The current version of SoundCipher is Beta release 10

For Windows users who get no sound when playing a note. Possibly the JavaSound file is not installed. Some versions of the JRE (Java Runtime Environment) do not include the soundbank in order to save space. Try installing a full (development) version of Java which will include the sound bank.
