Waldorf filters, version and cem numbers

[Hugo Haesaert]

Hi All !

There are 2 Microwave versions, one with cem3389 ser no starting 
lower than 94, and a later version with cem3387 with ser no starting 
with 94 or higher .  The MW3387 does not use the extra 3poles as anti-
alias filter .  Uses the same 4558 based filter as the MW3389 .  
These 3 poles are used in the Wave as high-pass filter .

The above loosley from an email by Wolfram Franke, answering me, 
asking about this stuff .

The "sonic" characteristics of all these filter ic's are said to be 
roughly the same, but not like the CEM3320, which is a different 
design altogether .

Bye for now .


Keep 'em oscillating :)
