Waves Real Time not working Live

I am able to record and then instantly apply auto-tune to vocals, and other waves plugin such as rverb are working fine live. However, when attempting to auto tune live vocals, no effect is applied.
Speed and note transition are set to the minimum, changing the musical scale does not affect whether live processing works, correction is on and set to 100%, and the range is set to suit my voice. Quite frustrating, any help would be much appreciated.

Hi @chopkins995,

First of all, I suggest contacting Tech Support to troubleshoot and figure out what the issue is.

But if you’d rather consult here - what OS are you running? what DAW/version? What Audio Interface?

Windows 10, FL Studio 20, and Scarlett Focusrite 2i4.
