Members ElectricPuppy Posted August 28, 2008 Author Members Share Posted August 28, 2008 Sir, I'll have you know that DCOs are far better than stinky ol' VCSs. This is common knowledge. Link to comment Share on other sites More sharing options...

Members Dave Bryce Posted August 28, 2008 Members Share Posted August 28, 2008 I suspect YOU of being slightly biased in this regard. Actually, I have this unromantic notion that it's simply not possible to listen to oscillators without hearing the other components in the synth's signal chain, and that the only true way to be able to do so would be to have the oscs in question in the same system, running through he same filters and amps. Sure, you can see them on a scope, and see that they both have grunge and artifacts, etc, but unless I'm missing something (always possible), there's no reliable way to listen to a raw osc. I've also been told by pretty much every synth designer that I've ever spoken to on the subject that how a VCO or a DCO sounds in a system depends more on how the designer handles the artifacts of the oscillator within the system than it does by what tells it's caps to discharge. It is a fun subject to talk about though, isn't it? I think there are great and not so great synths in both categories. dB Link to comment Share on other sites More sharing options...
Members kpatz Posted August 28, 2008 Members Share Posted August 28, 2008 VCOs drift, DCOs don't. That's about the only practical difference. Each has its place in synth-land. There are times when drift is good, and times when it isn't. Give me a good VCF anyday, and I won't care what kind of oscillator is behind it.

Members Dave Bryce Posted August 28, 2008 Members Share Posted August 28, 2008 VCOs drift, DCOs don't. That's about the only practical difference. Heck, there's even exceptions to that - Andromeda has the option of turning tuning stabilization on and off on it's VCOs, and the DSI DCOs have his oscillator slop algorithm. Each has its place in synth-land. There are times when drift is good, and times when it isn't. Give me a good VCF anyday, and I won't care what kind of oscillator is behind it.

Members Don Solaris Posted August 28, 2008 Members Share Posted August 28, 2008 VCOs drift, DCOs don't. VCO can be designed with minimal drift, almost zero, i.e. Andromeda, MOTM, etc. Only true difference between VCO and a DCO is that VCO shifts in frequency through indefinite resolution depth. This is what gives "fat" sound when you have two VCOs detuned as opposed to DCO's that go in "stairs" up and down in pitch (both fundamental and harmonics). With one oscillator system - difference isn't much noticeable, but with two slightly detuned VCO's vs DCO's, difference is: night/day. Same rule applies for phase and amplitude. Watching a raw VCO on a scope shows an ever evolving dancing waveform in: frequency, phase and amplitude. DCO on the other hand is rock solid. Regarding oscillator drift - these vary from synth to synth. Korg MonoPoly has ultra stable VCO's, but sounds thin compared to CS-15 that has horrible VCO stability, yet produces some of the fattest bass sounds on planet (though it doesn't have a big bottom like Moog or SH-2). Two oscs on CS-15 are fatter than all four on MonoPoly. Link to comment Share on other sites More sharing options...

Members urbanscallywag Posted August 28, 2008 Members Share Posted August 28, 2008 I'm not sure it has to do with "infinite depth" or quantization noise. An oscillator out of a 24 bit soundcard can have quantization noise below the noise floor. Link to comment Share on other sites More sharing options...

Members raffor Posted August 29, 2008 Members Share Posted August 29, 2008 Please specify modulation type. The audio output of one VCO can modulate the pitch of the other VCO. However, there are different kinds of cross-modulations, like linear and non-linear, etc. The important part is that the pitch of DCOs cannot be directly modulated by any Voltage signal.
