from yves:

The ARP4072 filter equipped mostly the famous ARP2600 semi-modular synthesizer.
I designed my own version of this filter. I have included in the design an input buffer stage and an ouptut buffer stage.
The output buffer stage is also used to compensate the loss of low frequencies that is generally observed at high resonance in 24db/octave filters such as the famous Moog ladder.
Curiously enough, neither Bob Moog nor Alan Richard Pearlman cared to compensate for this loss. This is strange knowing that it is quite a simple modification. Such compensation was introduced by Roland for the  filter of their nowadays very sought after TB303 !

On the two boards I built of this filter I obtained pure sinewave auto-oscillation at high resonance within the range 20Hz-20kHz, for the first board, and within the range 60Hz-20kHz for the second board.
