Hia,

I'd like to add a filter to my setup, thinking of a doepfer.
They have several interesting model AFAIC.
moogy: http://www.doepfer.com/a120.htm
oberheimerish: http://www.doepfer.com/a122.htm
I think I like the oberheimer a bit better as it is a bit wilder,
but I dislike that it's resonance can sound apart from the sourceinput.
What's your opinion?

Futhermore, they have a WASP filter http://www.doepfer.com/a124.htm
They say it's dirty. Did you ever hear it? And?
"Module A-124 is a special 12dB multimode filter using the "strange" filter
circuit of the "EDP Wasp" (an analog synthesizer with black/yellow case
built end of the seventies, manufactured by the UK company "Electronic
Dream Plant"). This design "abuses" digital inverters as analog operational
amplifiers leading to distortions and other "dirty" effects that generate
the specific sound of this filter. "

Then there is a 3 in a box, never heard this one either.
http://www.doepfer.com/a127.htm
Internally, each one switchable from BP to LP. Seems a nice
three in a box, but might be a little boring with only 12 dB/O?

Any comments?
Other modules from different brands that are far superior?


Thanks

Dave
