Sony’s unadvertised secret is you can download a fully functioning version of their loop-based Digital Audio Workstation totally free. Click the image above to go to the download site. This is NOT a trial. It’s fully working and never expires. Its just a lite version limited to 10 tracks and does not allow fx processing on individual tracks. Even with these limitations, its still pretty good. More advanced users could easily run fx on loops using Audacity (also free) then open them back up in Acid.
Sony Acid express is a great program for those just starting out making music with their computer. Its easy to use and automatically synchronizes beats (much like Ableton Live) but it was actually around before Ableton was.
If you’re wanting to get started making music, this is highly recommended. You just need to set up an account at acid planet by providing an email address. But it really is free and legal.
