You can record audio tracks, too. But it's the currently unmatched looping capability that dominates the package. Anyone constructing sample-heavy grooves will put it right to work, but sound designers, ambient and electronica artists, or game developers will also find it useful. In fact, ACID's learning curve is so shallow that almost anyone who can point and click can make music right out of the box. The ACID window is divided into three main areas.
Audio events display as clips, and clips are stacked as tracks.
Standard transport controls above, and the usual scroll bars and zoom buttons complete the work space. The display is clean, with each audio clip a distinctive color and loop boundaries clearly marked. Since you can change tempo and key in real time while files are auditioning, it's quick and easy to settle in on a good tempo, and just as easy to get wild. Even if it sounds ridiculous it will only cost you a few seconds to find out. If you like what you hear, click twice to load it to Track view, or simply drag it over.
