MIDI INPUT
MIDI IN
The Mother-32 has a 5-pin DIN MIDI input that allows for external MIDI control, 
MIDI clock sync and MIDI to CV conversion. When MIDI information is being 
received, the MIDI IN LED will ash red. Details of the MIDI implementation are 
contained in the “MIDI Functions and Implementation” section of this manual. 
 
VC MIX (VOLTAGE CONTROLLED MIXER/ATTENUATOR)
VC MIX
This is a DC-coupled, patchable, voltage-controlled mixer/attenuator that allows 
two different CV or audio signals to be blended together, modulated, and then 
patched to a new location. The VC Mixer is directly connected to the MIX 1, 
MIX 2, VC MIX CONTROL and VC MIX inputs. Mix 1 is normalled to 0V and 
Mix 2 is normalled to a +5V source. This enables the use of this module as a 
voltage source, an attenuator, a VCA, or a Mixer. It is not internally connected 
to Mother-32 synthesizer functions, and requires patch cables for use. 
PATCHBAY OVERVIEW
PATCHBAY
The patchbay contains 32 x 3.5mm patch points, which allow for 
extended synthesis capabilities and modular interconnectivity.
 
AVAILABLE INPUTS

VCO 1V/Octave, VCO Linear FM, VCO Modulation, LFO Rate, 
Mix 1, Mix 2, VC Mix Control, Multiple, Gate, Tempo, Run/Stop, 
Reset and Hold.
 
AVAILABLE OUTPUTS
VCA, Noise, VCF, VCO Saw, VCO Pulse, LFO Triangle, LFO

ASSIGNABLE OUTPUT
The output labeled “ASSIGN” is a multipurpose control output 
for selecting from a number of available functions. The default 
output is the Accent signal from the Sequencer.
