Fairlight-CMI

Anyone know what type of filters these have? Are they the same as the IIx (ie Prophet 5 VCF's)

Cheers,
Peter

CMI s III is said to use Curtis SEM chips., I can't however verify this information for obvious reasons ;-)

There is no such thing as a Curtis SEM chip. It's either CEM or SSM.

And no - no Curtis chips were used. The filter in the Series III is
completely different than the one in the IIx.

Hi Guys,

 For the record the CMI 2X used Curtis and SSM filters.

Rev 1 channels cards : Curtis
Rev 2                  Curtis
Rev 3                  SSM
Rev 4A                 SSM

I have still yet to decide which actually sounds better. At the moment I
feel that the Rev 3 / 4 channel cards sound slightly warmer and the filter
seems to open up nicer but its hard to say !

Regards,

James Thomson
