: During WWII, a massive vocoder system called SIGSALY (located in the basement of a London department store) was used to encrypt top-secret conversations between Winston Churchill and Franklin D. Roosevelt.
for Windows is a journey from 1930s telecommunications and World War II espionage to the modern digital studio . Arturia's software recreation is specifically modeled after . While the original hardware was a specialized effect requiring an external synthesizer, Arturia's version integrates a full analog synth engine and a sampler into a single "voice-transforming playground". 1. From Military Secret to Musical Tool
The "long story" of the Arturia Vocoder V Go to product viewer dialog for this item.
: By the 1970s, the technology entered the musical sphere. Bob Moog's 1979 design became iconic for its "robot speech" and rich harmonized textures, later defining the sound of artists like Daft Punk and Electric Light Orchestra ("Mr. Blue Sky"). 2. Modern Reinvention: The Arturia Twist
This LMC simulator is based on the Little Man Computer (LMC) model of a computer, created by Dr. Stuart Madnick in 1965. LMC is generally used for educational purposes as it models a simple Von Neumann architecture computer which has all of the basic features of a modern computer. It is programmed using assembly code. You can find out more about this model on this wikipedia page.
You can read more about this LMC simulator on 101Computing.net.
Note that in the following table “xx” refers to a memory address (aka mailbox) in the RAM. The online LMC simulator has 100 different mailboxes in the RAM ranging from 00 to 99.
