LOL, you would think so… but appears not to be the case, I think it loads media bay in the background.
It’s the one thing that puts me off using Steinberg VSTi’s… I either don’t use media bay for samples or I don’t use for Steinberg VSTi’s, as its impossible to load the next patch quickly without loading media bay. Even when you do open media bay for a VSTi preset you have the same wait while media bay loads, then OK it’s quicker to select one patch after another, but if you want to try moving the filter for example, the preset box closes and you get the same wait till the browser opens again, infuriating… 
In short, it really sucks… Your choice is either reduce your sample library or avoid Steinberg VSTi’s.
Steinberg if you read this please find an alternative way to load VSTi presets in your instruments……
Actually NKS would be great as I have a NKS keyboard 
would be nice to see Padshop as fully NKS.
