dann kind of talked about this previously on your other topic.
the vcv wrapper is pretty darn good, so native plugins dont get much of an improvement.
Id suspect also where it is an improvement, it’ll be more on the UI core rather than the dsp cores which is what you are focused on here.
really, the dsp side is much more affected by the algos you use, how you use the fpu and simd, rather than if its a native mm plugin or not.
Id be surprised if there is any generic reason that the 4ms modules use a bit more dsp cpu than others… other than perhaps, 4ms are spinning more plates, and so cannot focus solely on these MM modules as much as other devs can on particular modules.
