FarSpace2Demo was the second incarnation of FarSpace/NearSpace. Changes involved simplifying the processing, removing the antialiasing which was there to handle the anti-saturation code that got removed.
During this period FarSpace changed its sound around pretty wildly while not being awesome. I’m going to encourage paying attention to reverbs like Space, PocketVerbs, and even FarSpace3, but this is when FarSpace2 came out, and I do have it (but not apparently the demo) to support those who got it and might need a replacement copy someday.
If you want this, buy Space and ask for it by email, and I’ll send it.
