Hi,
not saying there's no room for improvement but please do not forget that Superior Drummer 3 is not your regular sample player, it's a virtual drummer/drum studio with all those sampled instruments through all microphones, with features and functions centered around that and the Toontrack expansions. The feature to add your own samples is pretty new in the Superior line, so you can't really compare it to e.g. Kontakt or simliar with regards to conventional sampler functions.
Stacking your imported samples should get you nearer, though. Did you try that? Use the Velocity Gate to set the different samples' Velocity trigger areas.
As for what may or may not come in future updates; apart from bug fixes, such things have always been communicated via the web site, not commented here on the Forum.
This is the 'Requests & Feedback' section though, so it's indeed the right place to ask for new features.
BR,
John
