ReaTune: Where did "Live input" check box go...?

This is Reaper 4.20, just DL'ed and installed:

It is no longer needed -- if you are not applying correction, it will not add latency. If you are applying correction, it will add latency, etc. :)

ReaTune is awesome, quick autotune and pitch to midi vocoding thanks to the fx mix knob at the top right of a plugin.

I'm not sure it works as well as before. The cursor in ReaTune's window seems to lag behind the actual audio being heard. But may be it's just on my system. (Edit) In fact, I've just installed the previous version of ReaTune and it works perfectly; the cursor follows the audio properly.
