I got a catalog from Serge/STS a few months ago and one of the modules that's causing me alot of confusion is the Frequency Shifter. What the hell is this thing? I've never heard of it before. After some web searches, I discovered a few other manufacturers who have built FS's - Moog (Bode), Buchla, EMS - but the information is scant and I'm nowhere closer to understanding what this thing actually does. The catalog informing me that I can do vibrato effects, robot voices, or Leslie simulations isn't much help either, since I could accomplish those using delays, phasers, ring mods, etc. And it's the most expensive module in the catalog, to boot!
Is this device related to: A vocoder? A ring modulator? An octave divider (i.e. where an oscillator tracks the input frequency)?
Can anyone offer a (simplified) explanation of what's happening inside a frequency shifter circuit? Or put up some .mp3's of a frequency shifter in action?
Thanks!
Igor.
