You've probably heard the output of Avid's Pro Tools audio production software, even if you don't know what it's like -- it's virtually a staple of the music industry, and spawned now-famous (or infamous) effects like Auto Tune. There hasn't been a cheap way to try it for nearly 15 years, however, so it's not exactly practical for crafting songs in your basement. Thankfully, Avid's about to lower the barriers to entry. It recently unveiled Pro Tools First, a free version that lets you get your feet wet. It includes a "subset" of the usual features (you're mainly missing extra tracks, score editing and video playback), but it otherwise behaves like the paid version. You won't have to relearn anything if you hit the big time and start using the full software.
