What a digital oscillator sounds like depends on alot of things. How it was synthesized additively, its contour and whether it has been oversampled and to what degree. Ideally it would be best to oversample at 192khz with a low pass filter over 22khz as this would push the Nyquist frequency faaar above the entire audible range of human hearing so that even extreme foldback from Nyquist manifests well above the highest frequency the human ear can hear.
For various reasons Vanguard's oscillators alias like mad. You can actually hear it which makes me wonder what kind of samplerate this synth is operating at internally. Even the non aliasing oscillators alias like crazy (although audibly less - try it yourself by A/Bing between them).
If a saw wave is a carrier wave that contains all harmonics, both odd and even in linearly descending amplitude up the scale, then the upper frequency ranges that exceed Nyquist will foldback. So Vanguard has a really messy top end and you can hear it so badly on hipassed sounds.
I should also say that the Virus's oscillators also alias but not nearly as much. However, I dislike the sound of the Virus oscillators alot. ImpOSCar's straight square wave is just so much more powerful than the Viruses. So is its saw and every degree of its PWM square.
The thing that makes the Virus sound good is its filter (without extreme saturation) and its modulation capability in the form of its LFOs and envelopes. The oscillators themselves sound incredibly weak without a tonne of effects.
And despite the fact that the Virus has a very Minimoog like saw wave oscillator, you can't really make convincing Moog leads on it because the Virus Filter sounds absolutely nothing like the Minimoog's Filter and doesn't behave in the same wave. And the Filter is what makes the Minimoog. |
Access released a patch for the virus to make the filters sound like the minimoog filters.
