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.

well... actually I can read schematics and the VC10 is very interesting in that way. it is clearly a 20 band vocoder. also, the VC10 is paraphonic. a nice feature for such a cheap machine.

bands - channels - all we wre doing here is confusing different terms for the same end purpose. A vocoder splits the inpout passband up into a number of discrete bands or channels, which are then used with envelope followers to control the carrier. Korg has got 20 circuits inside which, as has been painstakingly reiterated a nunber of times, accounts for the performance of the instrument. What makes it cheaper than various makes (e.g. Synton, EMS etc.) is that the channels are all fixed in their frequency reponse - there are not a multitude of controls like you might find elsewhere.

Anonymous is still sticking to his confused position but the fact is, the Korg VC-10 has 20 vocoding channels inside it. Or120 vocoding bands, whichever you choose to use as a descriptor; they are all fixed response unlike expensive Moogs etc.

Please accept the facts and stop posting nonsense!

Okay, I just searched on Google and found-out that bands and channels are NOT the same (if talking about frequency, which I'm not sure of here). Anyway bands are divided into channels (how many??), so there are more channels than bands. Yes the VC-10 has 20 channels (much to my bewilderment), but I'm not sure how many bands (if they're going by the same rules as frequency does). If it's 2 channels per band that would make it a 10-band vocoder. 10-band x 2-channels per band = 20-channels. Idk.

Here is an EXPERT confirming IT'S an 8-band vocoder, NOT a 20-band vocoder!! IT'S NOT A SENNHEISER, MOOG, BODE, EMS, NOR A SYNTON!!!! I also have literature from Korg stating it's only an 8-band vocoder!!! So NO you IDIOTS, I'm NOT confusing it with the microCRAP!!!

The VC-10 was my object of desire back in the late 70's, along with the SQ-10 sequencer. There's no way on earth to artificially reproduce the original series sound in all it's crisp juicy splendour. I owned the MS-20 then, and now you get (almost) the entire line with the MS-2000 (or microKorg, that is). But the upright console design plus colorful patch cables of the above three were so peerlessly arcane and sci-fi, gee.

Any of today's synths is no match for this massive monophone fun.
