v2.4.0-preview

This is a preview build of the upcoming 2.4.0 version release of the Sound library, available for manual download/installation until it gets pushed to the contribution manager.

How to test

Download sound.zip and extract the sound directory into your sketchbook's libraries folder (this is usually in Documents/Processing/libraries/). (On Windows, you will need to close Processing while doing this.)

We are particularly interested to know whether old sketches of yours that use the sound library still work as expected using the new library version. PLEASE REPORT ANY AND ALL BUGS, CRASHES OR EXCEPTIONS YOU GET WHILE USING THE CURRENT PREVIEW BUILD AT THE FOLLOWING LINK: #89
