I’d like to add that I’m seeing an issue where the VST3 version of v3.7.5 also doesn’t save settings in the upper right panel, where “Pitch Tracking”, “Low Note”, “Crossfade”, etc. are.

Additionally, I had an older project saved with a previous version of Quadravox (likely just one or two versions before), and when I try to open it with Quadravox 3.7.5 installed, it isn’t able to recall the settings and just loads with the default settings.

Seems like this version of Quadravox VST3 has general issues with recalling settings.  VST2 version doesn’t have any of these issues.

I’m on FL Studio v20.7.2, Windows 10.
