There were two major releases of the Prophet-5, one with Curtis chips
and
later one with SSM chips. The Curtis had rather wild temperature
senstivity
and so was replaced. Anybody who has used both found the newer models
to sound a lot thinner and some would prefer the
sensitivity/unreliability of
the former to get the sound quality.
The MiniMoog is a bit more esoteric, they did not used anybodies
chipsets
but mostly discrete components. Legend has it they the board layout
was
changed at some point and even though the design was the same those
in
the know did not appreciate the new sound.
I am pretty sure the Oberheim went through the same issues as SC. The
big Rolands are a separate issue - I think they used there own
chipsets but
I could be a bit wide of the mark.
Kind regards, nick.
I guess my Oberheim Matrix-1000 will use CME micro chips and I guess a
Roland Juno-106 will use CME too and perhaps SC and Moog (at least for
later synth) did use those chips too.
