If you’re wanting to get started making music, this is highly recommended. Its easy to use and automatically synchronizes beats (much like Ableton Live) but it was actually around before Ableton was. Sony Acid express is a great program for those just starting out making music with their computer. More advanced users could easily run fx on loops using Audacity (also free) then open them back up in Acid. Even with these limitations, its still pretty good. Its just a lite version limited to 10 tracks and does not allow fx processing on individual tracks. Click the image above to go to the download site. Sony’s unadvertised secret is you can download a fully functioning version of their loop-based Digital Audio Workstation totally free.
