Fabfilter Pro Q4 MIC NOT WORKING
When i use my Fabfilter plugins they all work except Pro Q4. My mic completely doesn't pick up. I tried the bypass feature and it still doesn't work. I just recently purchased, please help.

Hi Zach,
We'd need a bit more info on your setup. What DAW and OS are you using? Are you using your mic live with our plug-ins? Most hosts have a low latency mode, which will bypass all plug-ins that generate latency when you are recording. If you're using a spectral band in Pro-Q 4, the low latency mode may bypass Pro-Q 4 when on input.
