[sdiy] NJM-2069 (Another Korg IC)

[Bob Weigel]

It's used from seeing it there and diagrams and in the first case just 
being told,  in the DW-6000, DW-8000, DSS-1, DSM-1, Poly 800 I/II at 
least.  As far as I know Sigma was the last to use the Korg 35's. 
SSM2044 in the polysix and monopoly..the 61..I can't recall if they went 
back to the ota based filter like Delta?  Anyway I'm fairly sure those 
are the only synths..and they are certainly one of my favorite sounding 
filters.   And I have never seen any kind of internal spec on the 
chip.   As with the 35 external components set up the parameters and yes 
in at least the DSS/DSM they are switchable.  But then I hadn't seen any 
spec on the 35 til someone in here showed it to me some weeks ago!  This 
group has really been great! -Bob
