Emax

Hi, I have an emulator III rack with O.S. 2.42.  I use it a lot with 
an Sp1200; dumping sampled signals to the EIII for processing and 
back to the SP for playback. 

I have a pretty good selection of destructive editing tools on the 
EIII (especially for a 93 OS!).  I have a huge 256 tap lowpass/hipass 
phaselinear filter, all other IIR filter forms, compression, digital 
eq, etc...

My question is why Emu removed some of these filters from the EIIIx 
and ESI models.  They seem to keep the EQ and compression-- but 
that's pretty much all that remains.. any reason for this?  Or do 
they have these features in some OS update that doesn't get mentioned 
in the manuals?

Anyone know about this?

Hi,
Some EIII cool (but processor intensive) features were removed to make way
for better new features on the EIIIX/ESI's, this was probably becuase the
EIII had a co-processor and the EIIIX did not - although there is space to
fit one. The ESI range is just an EIIIX with smaller surface mount
components.

They switched to digital filters starting with the EIIIx, different deal, 
different things. The plain EIII is highly coveted for those reasons, the 
analog filter is really cool.

Note that the new Emulator X - the Emux =) - has a buttload of filters.

The EIIIx digital filters were, to my understanding, implemented in a 
separate chip--i.e. the burden of 32 channel realtime IIR filtering 
was not put all on the main processor but rather moved to a separate 
digital chip instead of separate CEM filters. 

The tools i'm talking about seem to have nothing to do with the 
realtime filtering datapath.  They are likely microprocessor 
algorithms run on the main controller; I think this is why nothing 
else can be done while the processing takes place.

Perhaps the co-processor matter is the decisive one.  What that 
really means i'm not sure.  What was a co-processor in terms of 1988 
technology?  Was this a separate DSP-type chip or some extra built in 
PAL logic to do transposing?  And why could it be removed (i.e. 
faster next-gen main processor?).. It seems the algorithms were just 
not deemed useful enough to be ported to later models.. oh well too 
bad.  I'm really pretty glad I bought my EIII rack though.
