The C110 2044 VCF is a four pole low pass filter based in
the classical filter SSM2044. This filter chip is responsible for
the sound of some well known polysynths from the 80s like the
Korg Mono / Poly , Korg Polysix , Korg Trident, PPG Wave 2.2
and 2.3 ,EMU Emulator I, Kawai K3, Sx-240 , Siel Opera 6 ....
The C110 is designed using the new reissued SSI2144 IC. It is
an updated version of the original SSM2044 with lower noise,
better control feedthrough but preserving all the sonic
characteristics of the original design.
Like many filters the SSM2044 suffer from gain loss when the
resonance is increased , the C110 includes an especially
designed circuit co correct that. This circuit can be activated or
deactivated on the front panel allowing the user to select
between the traditional response and the gain compensated
response.
The C110 has temperature compensated voltage control and it
will oscillate at high resonances. It can be used as an oscillator
over 3-4 octaves.
The C110 main characteristics are :
- Four pole response ( 24db/octave )
- Gain compensation circuit
- Three modulation inputs one with an attenuverter
- Voltage controlled resonance
- Temperature compensated
- One audio input
The FM2 input has a 0,66 V/Octave response expanding the
modulation range to 7,5 octaves using the typical 5V envelope.
