A substantial mythology has formed around the soundtrack's creation. One of the prevailing notions is that the sounds were generated by torturing and electrically overloading the "cybernetic circuits". There's evidence that this is simply artistic misdirection.
In reality, the music was carefully crafted and performed - with an emphasis on performance, rather than random events and sounds. (The genre of "Krell music" went off at a completely wrong tangent in this regard...)
It's unfortunate that Bebe Barron downplayed her own compositional technique and creative input in order to bolster this mythology.
The research is focused on the nature of the Barrons' cybernetic circuits. Using digital equivalents of these circuits, the aim is to recreate the title track, using only the techniques that were available to the Barrons in the 1950s.
