Korg VC-10 Vocoder

Korg VC-10 Image

Isn't it cute? It's a little polyphonic 20-band vocoder offered by Korg. Feed it your voice (or any other interesting sound source) and synthesize it! That is, control the sound of the synth with your voice. You can even put other sounds through its filters which will then be processed by the vocoder. This basically means you can use it as a talk-box with a guitar, for example or you can use it to add a twist to your drum loops. Other than that this machine is pretty limited. There's a nifty little analog VCU input meter. It has been used by Keith Emerson, Apollo 440, Klaus Schulze, Tomita, Labradford, Rick Wakeman, Roger Waters, Joe Zawinul, Tangerine Dream, Goldfrapp, Air, Pink Floyd and Yes.

I actually found an old owner's manual and service manual (after my comments here) that I got from Korg years ago (I forgot I had them). I couldn't believe it when I found-out that it does INDEED have 20-channels!!! But those twenty channels are nonadjustable unlike the Roland SVC-350 Vocoder and the EMS Vocoders which have adjustable channels. My deepest and sincerest apologies to all.

Yeah, it's 20 channels vocoder: look here the PDF manuals

I have one since 2006. Hard to find here in Brazil, even being a cheap machine in its time...

George (and "Anonymous"): take a look at the 49MB PDF service manual which somebody has stored here:


( http://alturl.com/5abfd if that's mangled)

Have a look at KLM-134 (the 9th page in, of 19 pages)) which shows the 20 channels, the top four of which have sibilant noise added.

Each channel is shown with different passband characteristics; the first channel spells out the carrier/modulator channels with opamp architecture which is then duplicated for the remainder.

As I said before, there are 20 channels open for anyone to see if they can read a cct diagram. There can be no debate.

George and Anonymous are absolutely incorrect. They don't know what they're talking about.

anonymous is absolutely correct, it's an 8-band vocoder. read up on your specs before attempting to correct someone who knows what they're talking about :)
