Ever wonder what chips your old analogs use?

I was wondering if the Prophet 5 Rev 2 and Korg Mono/Poly and Polysix all shared the same SSM (Solid State Music) filter, so I shot an email to AH. But then I remembered, duh, it's probably on synthech. The Rev 2 used an SSM 2040 while the Mono/Poly and Polysix both used the SSM 2044. If you are wondering what your synths might be using or if you are just curious what synths had what chips in common take a look at the list. You'll be surprised to find out different synths used the same Curtis chips. Note that the design of the synth and implementation of the chip made a huge impact on the actual sound of the synth, so two synths like the Prophet 5 Rev 3 and Oberheim OB-Xa which used CEM3320 VCFs will sound different. Other synths that used the CEM3320 were the PPG Wave 2.0, PAiA Proteus, Elka Synthex, Crumar Trilogy, SCI Pro One, SCI Prophet 10, Lindrum, and CMI Fairlight II. Pretty versatile chip. : )
NOTE: Synthtech is also home to the MOTM modular. Check em out.
