Propellerhead Software has retired the software that came before Reason and made them big: ReBirth RB-338.
Check out the ReBirth Museum for more information about the History of ReBirth. This is also the place where you can download the original ReBirth CD-ROM Image as well as ReBirth Mods, songs and third party applications (free registration required).
You can also download the ReBirth RB-338 ReFill if you are a registered Reason user.
The commemorative ReBirth t-shirts say: “ReBirth RB-338 R.I.P. 17 05 1997 – 01 09 2005”, but it is likely the community will not let it rest just yet.
