You have the generic sliders for any vst, but not for vsti. I know that taktik also implemented the generic vst view for vsti (same vstis don’t have a go at all). Now some older plugins behave erratic when it comes to the GUI (e.g. tal noisemaker on macos 10.12++). nice would be a context menu entry “open generic GUI” for any vsti.
You could perhaps use an Instr. Automation device to achieve pretty much the same thing?
Sure but the generic view is a floating window. Well you are right.
