The Korg VC-10 is an analogue vocoder launched in 1978. Vocoding refers to voice encoding of speech and singing with musical synthesis. It gained popularity in the '70s following utilisation by bands such as Kraftwerk and Electric Light Orchestra. The VC-10 allows basic functionality in operation and modulation of signal carriers. It has two microphone input options.
The VC-10 "achieved a measure of popularity because it was simple to use, relatively inexpensive and completely self-contained." It features 20-channel polyphony, ensemble mode with speed and depth controls (akin to a chorus function), accent bend control (adds a slight pitch wavering effect so that the sound produced is more like a human voice), octave-up control (extends the range of the keyboard), and tune control as well as various settings relating to input and output mix.
Microphone input options
The unit was originally supplied with a gooseneck microphone (the Korg MC-01) which plugged into a bespoke BTS connector. This type of connector is now obsolete. It appears to have originated around 1965 and was phased out when XLR became the standard in later years. It is difficult to source a microphone that will connect to it but TOA Japan  still (as of Jan 2015) makes a compatible model, the DM-524B. The unit also has a front panel standard microphone phono input jack.
Use in popular music

|Roger Waters||(used in Animals (album)) "Floyd first used a Vocoder in Animals (recording during 1976) for Roger’s lead vocals in “Pigs” and for the bastardised psalm on “Sheep”, as well as for the treated barking sounds and other effects in “Dogs”. Rick’s keyboards were also fed through the Vocoder, notably during the middle section of “Dogs”. Although it is not documented which particular model was used in Britannia Row studios for the recording of Animals, it is reported that they used the -now classic- Korg VC-10 model"|||
