YC-3B VCM engine same as YC-61 engine?

I use the Yamaha organ plugin YC-3B which has VCM modeling. The question is: does the YC-61/73/88 use the SAME VCM technology? I am considering purchasing the YC-61, but if the VCM technology is identical or similar, I can just continue the use of the YC-3B plugin and get the same sound.

And … YES … I am aware of all the OTHER great features the YC-61 has, in addition to organ sounds. But what I am really asking in this post is exactly how similar the VCM modeling is for the YC-3B vs YC-61.
