No probs, btw been trying out Spire now, not bad eh Reading the manual now, and I guess the filter types named "Red" in the scorpio filter mode are the Nord Lead based ones? Being used to the Virus TI2 interface, it feels right at home with the structure/layout of the synth. By messing around some, I think one aspect it don't really manages perhaps to capture fully from the Virus, are the pads. But I've just scratched the surface so far, as far as arps, leads and basses go, and to some extent FM-bell type sounds, it's in the Virus ballpark for sure.
"These are the filter modes and their respective types:
Perfecto a unique algorithm that combines the best characteristics of analog anddigital filter types. Great for a broad spectrum of sounds. Modes: LP4, BP4, HP4, Peak
Acido type does not repeat at 100%, but good for simulating TB-303 sounds and not only. Modes: LP1, LP2, LP3, LP4
Infecto type does not repeat at 100%, but simulates the filter sound of a Virus TI synthesizer. Modes: LP2, BP2, HP2, Notch
Scorpio another unique algorithm by our team that combines the best characteristics of analog and digital filter types. Great for a broad spectrum of sounds. Modes: RedLP2, RedLP4, BlackLP2, BlackLP4, BlackHP, BlackBP
Combo filter consists of a series of regularly spaced spikes, giving the appearance of a comb. Modes: Mono +, Mono -, Stereo +, Stereo -"
