On Linux there is a parameter in the JACK settings for the maximum number of 
ports it can use. This has to be set before you start the JACK server.
I assume there is a similar setting in JackOSX.

So in your case, you'd want the maximum to be  9 * 96 channels. (8*96 for the 
scsynths, 96 for the actual hardware ports).
