I just downloaded the new version of this software (I was running 1.8), and I wasn't sure if I've ever posted it up. Since theres a new version, I thought I should anyway:
Renoise is a module tracker unlike any other. It is free, but it has limitations (but not that many). I'm planning to support it by buying it as soon as I finish my first album. Its cheap, considering what it offers.
Download this free album which was made in it, and I guarantee you'll be shocked, if you don't know what a brilliant tracker can do:
What may surprise you more, is it was written in less than 28 days!
You can either download the files to play straight through the tracker, or the album as an MP3. I prefer to see the song moving through, and decoding on the go, so downloaded the tracker version to play within.
If you are at all into making music, and have tried many softwares, try this, honestly.
