Not sure what you mean. But by default the oscillators on the virus behave like analogue, that means "free running", try to adjust their "phase" and it becomes more steady - saying this because sometimes this can create some sort of click, with very snappy envelope settings. If you think it's hitting hard, take away the punch intensity all together. About Timo's tip: it's called recursive modulation, very useful and shouldn't lead to any increase in attack time, it's just the curve that changes, also can be done for the decay and release. I don't agree that the envelopes behave badly on the virus at all...
maybe post an example for us to listen to, would be easier
