Doepfer

Yes, I should have added that while the TB-303 has the most widely-
known diode filter, emulated on umpteen computers in ReBirth, in 
Oakley's superladder filter and TB-3031, and elsewhere, it's 
basically a -18 dB version of the Moog design, and that the Doepfer 
diode filter would be patterned on the EMS, as is the version sold by 
Modcan.

People who want to get a sense of the sound of an EMS-type diode 
filter can check out this mp3 of the Modcan version:

As you'll hear, yes, it has a unique sound and definitely not that of 
the TB-303 (which also has a unique sound).
