12db Oberheim Filter clone	This filter has been modeled from my Studio Electronics SE-1x and the ATC-X. The filter is very close to the real analog one. Lowpass and Bandpass. read more...

Here is my emulation of the 12db Curtis Chip used in most Oberheim (CEM 3320). This emulation has been made from recordings I've made at Eric Englebert studio with his Xpander.  I've reworked from the Studio Electronics SEM cartridge I got from an ATC-1 and this filter is very close to ATC filter sound.

This filter has only low pass and highpass output by design, and has a very stable resonance, very smooth compared with the Moog's ones.

Input : input audio signal.

Resonance : level of the feedback in the final result. At highest level the filter will start self oscillating. Use the frequency parameter to 'tune' the feedback with your tone.

Frequency : frequency of the filter. Well you are supposed to know what it is.
