ACID Pro uses Acidized loops (Acidized meaning they contain tempo and key information for proper pitch transposition) painted out across the screen to create music tracks. Many Acidized loop sample cds are available from Sony, as well as a number of other companies including : Peace Love Productions, Big Fish, Perimeter Sound Arts, and Power FX to name a few of the top loop sample content providers.

As with most sophisticated software packages, ACID is not a single software product but defines a family of products spanning a significant range of features.^[1] In a related-marketing effort, Sony has launched a content web site, ACIDplanet.com, aimed at current ACID users, prospective ACID users and the general public that self-describes itself as "the Internet's premier site for music, video and unique artists".^[2]
