Hi kbrkr,
please do not take me wrong:
All Wersi OAS instruments come loaded with many hiqh-quality sounds out of the box,including Grand Pianos,Guitars,Brass etc.
All the sounds are high quality multi samples,stored in the Hard disk and not in ROM.
Drawbar organ sounds are provided either by hardware (OX7) or software generators.
On top of that more sample-sounds can be loaded (in AKAI S100/300 format)and any sound in .wav format can be used to create user drumsets.
The ability to intergate VST plugins is OVER AND ABOVE of all these and definetely not a prerequisite to use of the instrument.
And although V7 would be capable of hosting 4 VST plugins,it comes with the new additional software sound generators and sounds thus making the need of plugins less.
