So I was using Vult Lateralus as the LPF for my Moog Subharmonicon emulator patch. But I had begun to notice that when I included a sin wave in the mix, I would get disconcerting mid to high frequency static in the output, similar to noise. I had to turn the incoming mix way down to (mostly) eliminate the static. I tried to investigate, and I never got the static with a monophonic signal coming directly in. It always seemed to be a combination of mixed audio fed into Lateralus.
When the input was a mixture of any wave forms other than sin, then all sounded good. I don’t know if the many harmonics of the other wave forms mask the noise, or if the sin wave itself somehow triggers the noise.
Changing to other filters eliminated the unwanted noise, though in other ways most did not have the sound I was looking for.
Recently I swapped out the Lateralus and substituted the Lindenberg Research Alma. I am very happy with the result.
Has anyone else experienced anything similar with Lateralus? Any ideas on what is going on?
