SSM 2044 Lowpass

Not much to write here. I just copied the schematic of the SSM 2044 design of the KLM 366 Korg Polysix schematic. It works fine, the only modification is that PIN15 goes just to ground via 200 Ohm. And of course, frequency control (PIN 13) is fed by the output of a summing amplifier (Offset, in1, in2). The output (PIN 3) goes to a buffer (see datasheet).

Below, the clipped filter section of the KLM-366 schematic.

Here is the oficial datasheet of the SSM2044. Data sheet
