Hi George,

From: http://www.soundonsound.com/sos/feb08/articles/dsiprophet08.htm

Knowing that the traditional CEM chips used in the early Prophets no
longer exist in significant quantities, I asked Smith how the Prophet
'08 came to have Curtis filters. He told me: "We're using a customised
part that Doug Curtis designed a few years back for the Evolver. As you
may know, Doug passed away recently, but his company, OnChip Systems,
are still manufacturing the chips for us. The part is similar to the one
that Tom Oberheim used in his 'Marion' series of synths a few years
back, which in turn was a variation of an older CEM part. In my opinion,
this filter has a ballsier sound - I usually avoid using descriptors
like that, but everyone knows what it means - than the CEM3320s we used
in the later Prophet 5s, the Prophet 10, and the Pro One, and I think
that this is noticeable if you compare the Prophet 08 to the older
synths."

Cheers

Chris
