No it's not. Remember the local oscillator needs to span a range of 17 octaves ( not far off from Paul's ultra VCO, and that VCO alone costs $349 assembled. ) and so to get real calibrated CV, you'd need CV control of all that. In reality, you could choose a small range, but since this has application far different than an oscillator, calibrated CV isn't very important. What are you calibrating anyway? You're taking an input frequency spectrum and shifting it by X Hertz. As soon as you start to shift your entire harmonic relationship starts to get mangled, so really what's the point to CV control other than to allow modification of how "messed" up things are getting? Once you shift too far, things all sound basically like chipmunks.
 
The beauty of really slow shifts is apparent in spacey music. It has a gorgeous lush rising (or falling) sound.
 
A digital local osc would only make it better.

Hm?  You're saying it's not calibrated for 1V/oct?
 
When you say a digital oscilator, what exactly do you mean?  A DCO?  A value-lookup table?  The only thing that makes me worry when I hear digital oscillator is the "stale, cold, frigid" effect.
 
But I have no idae if this would come into play, since I don't know how a frequency shifter works.  Thanks!

Sorry for the huge delay replying to this. I've been really sick for over a week now.
 
The FS shown at NAMM is neither of those things, but one change that is being considered is having the local oscillator change from analog to digital, and this would cost effectively provide both features, and a wider range of shift. (Especially at the slower end) The multipliers would still be fully analog and so would the entire audio path. The price wouldn't change, but the ship date would slip. I think it would be a better product overall, but maybe other's would disagree.
 
Now's the time to speak up. Everyone I mentioned it to at NAMM thought it was a great idea.

Frequency shifter?  Yes!!!!  Shifts through zero?  Calibrated 1V/oct input?  If so then this is a great price.

 

Bigger knobs on this one please.  An oversized one for Manual Shift would not be out of place.
