yes, sorry i forgot to mention this does only happen once ive used unison but i never experienced this problem before in the last few years regardless of unison. if i think about it now, it pretty much sounds like the filter is modulating for each count of unison individually.
i would imagine the "mono' switch on the lfo to take care of this but it dosnt.
i never used to have this problem and if i did then im missing something now since i havent used virus for a month or two.
