SC589 max channels in SS-Sharc 128?

I and trying to determine appropriate tool to create a Project using the SC589.

The requirement is for large channel count.

MCLK 49.152mhz

Sample Rate 48k data 32 bit. on all Sports

Sport x-A   TDM32  

Sport x-B   TDM32

6 Pairs of Sports used.

 Thus 384 channels in total in and 384 channels out

However in SigmaStudio for Sharc looks like I cannot choose more than 128 per core?

Is it possible?  or do i need to do this in Bare Metal in CCS?

or can Visual DSP be the better tool?

Thanks
