The sound of the new filter might not be so obvious from the demos, I guess. Sure, you might *think* that the original Virus filters are capable of making those sounds, but actually they are not. The self-oscillation is more than apparent in the demo labelled 'Self-Resonating Sphere' - *all* of the top end warbling above the basic chord sound is courtesy of the new Analog Filter!
The Saturation that is integral to the character of this filter algorithm is also very different from what can be achieved with the original Saturation types - it is much warmer and more subtle (and consequently more natural-sounding) than those. If you simply run a pure Sine wave through this filter, the character is entirely different from that achieved through the standard Lowpass. The Moog-style Saturation also affects the signal with a certain amount of compression, which makes certain effects only possible with this algorithm - for instance, if the Oscillator Mix signal is made up of slightly detuned waveforms, the beat-pulsing results in peaks and troughs in the signal that another signal, ie Noise or Sub-Osc interact with. All this means it now much easier to create pulsing, breathing, organic sounds that could only previously be imitated with complex ModMatrix routings (and less convincing results).
I'm afraid the only way to truly appreciate the beauty of the Analog Filter is to build a simpe patch, turn Resonance up a bit, and sweep the Cutoff. Something magic and undefinable happens now within that sweep that was never possible before..
