Bernard was kind enough to put together this excel spreadsheet with information about all of the mSG processors in Studio Artist V4.
It breaks them down by their IO routing.
And perhaps he can comment some more.
I don't have Microsoft Office Excel on my computer right now, so i can't look at it directly. But he asked me to pass it on for people to download, and it is currently being discussed and examples of it shown in this image post.
Let me know if i need to zip compress it, i just tried attaching it first below.
