Casio CZ/ VZ/ FZ - Pro Series

Here is an interesting looking new VSTi from reFX. It is not directly 
stated but judging by the name, the functions offered and the sounds 
this thing makes I am confident that it is related in some way (if 
only inspired by them) to CZ synths. I am stoked IMHO reFX are second 
only to Native Instruments when It comes to developing quality 
softsynths and this is one of the best. reFX also do the quadraSID an 
emulation of the C-64 sound chip I would think that if you are into 
the sound of a Casio CZ then the quadraSid should also light up your 
ears.
