hatembr.. I've been playing with Hipass, lowpass etc... I was just talking about the SER buttons next to the filter settings... what the hell are those.. are they different filter emulations?

this is in the manual.
the virus has 2 filters. you can configure them in various ways to get various different dB slopes using the filter routing buttons and the filter balance.
series 4 = both filters in series, both with a 12db slope so that using both filters with the filter balance set to 0 results in a 24/db slope.
series 6 = both filters in series, first filter with a 24/db slope, 2nd filter with a 12/db slope so that using both filters with filter balance set to 0 results in a 36/db slope (access were so happy about this that they mention it about 3 times in the manual and once in the introduction)
parallel 4 = each filter in parallel, both with a 12/db slope.
split = splits both filters so that you can effectively play two sounds at the same time from 2 different oscillators. i.e. a saw tooth sound on oscillator 1, shaped by filter 1. a white noise, hihat type sound on oscillator 2 shaped by filter 2 with both sounds playing independantly through separate filters.
you can even get a low pass 3 pole filter with an 18/db slope like on the novation supernova and tb303 by setting the filter routing to series 4 so that the filrst filter has a 12db slope then setting the filter balance to -32 whilst modulating the first filter cutoff.
