Free Cakewalk Audio Software
I don't know how long this offer lasts but there are several Cakewalk Products available on their site for free download.
You will need an Audio/Sequencing Host software to run the FX Packs (examples: Sonar, Cubase, FLStudio, Orion, Reaper, etc) as they are NOT standalone. Square1 and SFZ+ have VST and Standalone versions in their installers.
All are Windows-only.
