Very simple yet quite effective in situations where you need it.
One thing to note though: I have experienced noticeable lag/delay of a tracks signal output whenever this effect is in the tracks chain. This happens whether the effect is on or off. Tested it a few times in different scenarios, same thing happens. It isn't too big of a problem for me, as I use it only in a studio situation and the lag doesn't affect my overall mixing/mastering workflow. Just a small thing that could make this VST much better.
By the way I'm using it in ableton live 9.6 (64-bit) on a PC laptop running Windows 8.1 (64-bit).
Sorry for my very late answer here, but this was already answered in the forum: sTilt is a linear phase filter which creates by design a delay of the signal. Usually this is compensated by DAW PDC, but it does not work in live situations, sic.
