TX16Wx VST is/was based on the hardware Yamaha sampler. should be plenty out there that is similar and applicable to the VST.
I used the VST a couple of times but in the earlier version I ran into crashes and bugs. Then I got Kontakt and just moved on.
If E-MU had continued supporting and one was able to purchase Emulator X I would go that route in a heart beat. that plugin was feature rich and nice, but it's so buggy from what I hear that it's not worth it on newer Windows.
I don't know of many sampler VST plugins that actually sample now that are around. Kontakt doesn't, Mach 3 doesn't. They have features of a sampler but it's mostly post sample editing, scripting etc.
I miss my EMU EMax II hardware rack so badly with that wopping 10 meg hard drive, I thought I was in sample heaven. ahhh for the old days.
