QiRexSound has released QiRex Player, a simple VST instrument plugin which loads SFZ files. It has attack, decay, sustain, release and gain plud master volume. The current version is for Windows only.
If you’re looking for a simple and fast SFZ player, than QiRex is what you need. The author plans to add to it more features like reverb, for example. We tested it into FL Studio and it loads and performs great.
And to give you some material to work on, please check the Pringles Drum Kit in SFZ format.
