Can We Automate The Start And End Function Of A Sample

That is just the limitation of VST plugins…
With Audio routing, you can at least split the audio streams each sample provides…
EWQL SO Gold allows me to apply the same amount of parameters for each designated instrument within the plugin… Doensn’t Kontakt allow for this?

With a third party vst I will agree on that. But the meta device would be native to renoise, which means that it could be integrated with the functions of the program.

What do you mean by “you can at least split the audio streams each sample provides…?”

I thought you were actually speaking about a VST, i misunderstood, your last question is in relation to VST multi out routing which is not applicable in this case either then.
