Patch diagram for a VCS3, for sound effects for “Poetry From Prisons”. This was how you kept track of the settings on a VCS3 in hopes of replicating a sound at a later time; the numbers in the circles describe dial settings, and the grid represents the pin board.
Just in case you need to get “fishes” or “whales” sounds on your EMS VCS3.
(Yeah, i’m going to reblog lots of these BBC Radiophonic posts.)
