You might remember this one being announce back on 9/6/2008. It is now available via BrideChamber. Not official NAMM news, but it is new and it is NAMM season so I'll add the labels for those looking."From Ian Fritz, The DoubleDeka Ultrasonic VCO is here!!!
From the Documentation...
This unique VCO consists of an ultrasonic oscillator core followed by a parallel pair of waveform generators. Each waveform generator consists of a switched multi-octave divider followed by circuitry to generate a 10-step waveform using a set of 10 slider potentiometers. Also included are a novel synchronization circuit with two different operating modes and a built-in "digital ring modulator" (DRM) for producing a wide variety of synchronized and anharmonic sounds. The oscillator core is highly stable (better than 20 ppm/K in the prototype) and features wide-range, accurate tracking (better than 0.05% over fifteen octaves). The variable waveform generator provides fine control over an enormous range of available timbres."
Drawing a waveshape for an audio oscillator, especially with only ten segments, it pretty useless and doesn't really relate to the sound in any intuitive way. Should have harmonic/phase control.
ReplyDeleteThis could be useful for an LFO.
You don't "draw the waveshape" on the DoubleDeka.

I daresay Ian Fritz understood that a ten segment waveform would be a trite function long before a majority of the readership of this blog was even conceived.
LOL.
ReplyDeleteWell, if you draw a Saw, it sounds like a Saw. Intuitive enough for me. You would prefer to dial in the exact amplitudes of 50 harmonics? And how would you make such a device, using analog electronics?
I've used this module for over 30 years, and I wouldn't have put it out if I -- and numerous other folks -- didn't think it was useful. It gives an incredible variety of sounds in a simple package. Way more than any other analog VCO I know of.
More accurate and stable than most, too. Tracking to +/- 0.05% over 15 octaves. Drift under 50 ppm/K.
Having only ten steps does give it a characteristic somewhat edgy sound. I happen to like it. Others may not. (That's why we have "filters".)
Listen to the demos and decide. I don't make any money off these -- It's about sharing something I have found useful with the community.
Boy was I in left field on that one - you do draw the waveform....
ReplyDeleteOh well, sounds pretty dang good to my ears. Do check out the samples.
Sorry about that....I'll crawl back under my rock now.
