I was just listening to the "I Robot" album and was wondering what
the "Projectron" is...? It is listed as one of the instruments on the
album... I did a search and found this from the Parsons web site...
interesting.
" Q. What was the Projectron, which featured on some of the earlier
albums?
A. The Projectron was effectively an analog "sampler". It could
therefore produce any sound fed into it. It was a little like the
Mellotron, but was capable of much higher quality. Usually it would
reproduce tape loops individually recorded to a 16 or 24-track tape
machine. The attack and decay times were adjustable using voltage
control technology. One of the most featured sounds is the female
background vocals on Breakdown. The Projectron looked something like a
keyboard synthesizer but with lots of sockets on the front panel for
connections to a multi track tape machine. Sadly, there are no known
photos of it and it has disappeared into the annals of legend."
