I can only assume since countless others have this working fine in Reaper that the issue is my system. BIAB works fine. Reaper works fine. But the VST3 is mute and the plugin standalone is non functional. I can certainly break BIAB by playing with drivers. Even Reaper can be stopped with Driver changes. But nothing brings the VST3 to life.
Perhaps my Motu Audio Express is an issue. It is one complex beast. Problem is when it is working it is great. Messing with this can certainly kill sound. But those adjustments don't fix the Plugin.
Can't tell you how upsetting this has been. Oh, maybe I did mention that in the past.

The only possible upside is I have started to seriously wean myself away from the forum. My wife says I spend too much time here. If I can't get this fixed I suspect I will simply fade away. Just to taxing on me.
