Sigmastudio server Matlab register write- what's missing?

Hi all, I'm writing Matlab code to control an ADAU1772 through sigmastudio server.  I can do register reads, but writes aren't working.  Here's the Matlab code for a write:


SS = actxserver('Analog.SigmaStudioServer.SigmaStudioServer');
ss_server = SS.invoke('ISigmaStudioServer');



b=ss_server.REGISTER_READ_ARRAY('IC 1',224,4);  %This works!



ss_server.REGISTER_WRITE_ARRAY('IC 1', 224, 4, b) %But this doesn't!!


The write generates this error:

Error using Interface.2942E58A_4461_410E_87B3_64152C81935F/REGISTER_WRITE_ARRAY
Error: The parameter is incorrect.


Does anyone have any idea why the write doesn't work?  I thought maybe I couldn't write the the active bank, but that doesn't seem to be the problem.
