How come the Live button actually creates a slight delay?

[sp33s]

I've owned both a Virus Snow and a TI Desktop, and both seem fairly dodgy when it comes to playing arp's (not via the arp in the synth, but by midi notes). I've tried to use the Live button in the Virus Control VST. This does seem to stabilize it, BUT it creates a small delay, which is particularly annoying during arps. In short, is this normal, or am I doing something wrong?

NB: I'm using a Focusrite Scarlett 8i6 via its ASIO drivers, and Presonus Studio One as my DAW.
