First, thank you for your kind words.
For Damper, I also don't like that behavior but so far I am not smart enough to figure out how. Oversampling, we're trying to do "as much oversampling as we need" but we can let you force it on/higher for sure. For the varispeed, I'm also not smart enough to do it in real time - maybe if we load the sample into the plugin, I dunno. I'll put all this on the roadmap !!
