They still have a website,
http://fatar.com. Their current offerings are sold under the Studiologic brand. The Fatar link takes you to a history and philosophy of the company. Following the Studiologic link takes you to
http://www.studiologic-music.com/ where you can see a list of current offerings. Manuals of their older devices are available as .pdf files.
The 49-key MIDI controller previous to my present M-Audio was nominally a private-label no-name device, but was ultimately manufactured by Fatar. I got it in the mid-1990s. Between one use and the next it quit generating MIDI output, although it powered up fine. I gave it to a repairman.
