FILTER PATCH POINTS
These Filter module patch points 
provide a convenient way to 
independently modulate the Cutoff 
frequency of VCF 1 and/or VCF 2, 
and to modulate the value of the 
ENVELOPE AMT knob. In addition, 
audio inputs and outputs allow each 
filter to be used as a stand-alone 
processor for filtering any internal or 
external sound source.
VCF 1 IN
The input to VCF 1 is connected to the output of the Mixer module. Patching 
an audio signal to this input overrides the Mixer signal, allowing any audio 
source to be processed by VCF 1. 
NOTE: The path and mode of VCF 1 are determined by the FILTER MODE switch.
AUDIO INPUT: -5V to +5V
VCF 2 IN
The input of VCF 2 is connected to the output of the Mixer or VCF 1, depending 
on the position of the FILTER MODE switch. Patching an audio signal to this 
input overrides this signal, allowing any audio source to be processed 
by VCF 2 using the filter’s current settings. 
AUDIO INPUT: -5V to +5V
VCF 1 OUT
The audio output of VCF 1 is available via this jack, allowing it to be sent to any 
input on Matriarch itself, or to an external electronic music device.
AUDIO OUTPUT: 10V peak-to-peak
NOTE: VCF 1 can be used as a stand-alone audio processor.
VCF 2 OUT
The audio output of VCF 2 is available via this jack, allowing it to be sent to any 
input on Matriarch itself, or to an external electronic music device.
AUDIO OUTPUT: 10V peak-to-peak
NOTE: VCF 2 can be used as a stand-alone audio processor.
