This is wrong.  The 96Kis a different animal all completely. It is a
floating point DSP.  This also means that data formats are different.
With floating point you typically get more dynamic range but less
resolution.  The 56K has 2 56 bit accumulators and can store 48 bits to
memory.  The resgister size is 24 bits but you can concatinate 2 regs.
to get 48 bits.

It is ideally suited for audio since it ca get a left and right sample
with out much trouble.

The 96k has very few uses for audio currently.  Most synths that use off
the shelf DSPs use the 56K.  I have seen very little software for th 96K.
This means a lot if time and investment writing code.  The 96K and 56K
are NOT sompatible.
