And yes, it is a Plogue authorized SFZ version of SM Drums for Sfrozando !
What's so special about it ?
'Authorized' means it has a proper GUI with some spiffing controls for all the kit pieces / buses. That's right, it has a one stop for all controls right there in Sforzando. And Sforzando has a pretty neatly implemented DFD (direct from disk streaming). And the Sforzando vst/standalone is free, as is this drum library. Do I need to draw you a road map here ?
What's in there ?
There's around 2.2 GB of beautifully multi-sampled collector's drum kit insanity (many velocity layer and plenty of round robins) , the sfz files, the GUI files, plus a manual and track templates for Reaper and FLStudio.
There is a version for a single instance of sforzando, that lets you play the whole kit and control some crucial parameters from there, for a stereo out.
There is a version for every single drum bus, where you can have multiple instances of Sforzando on separate tracks in your DAW to apply external FX on each drum bus.
