 In details 

Moog

The VX-351 connects to the Voyagers accessory port with a sub25.
It features  21 jacks that are connected to the CV and Gate outputs

The CV sections is organized in 6 sections: Touch, keyboard gate, wheel, pedal bus, envelope and samplehold.

351 also features  two 4-way multiples (buffered) and two attenuators - great for use with modular systems

19x CV I/O

 2x gates

2x attenuators

CV and Gate I/O description

Touch

TOUCH This group of outputs is generated from the Voyager keyboard’s Touch Surface Controller.
X is the CV generated by horizonta position of contact, Y by vertical contact, and A is the CV generated by the amount of area covered on the touch surface. Finally GATE is a gate signal generated by contact with the touch surface. 

Keyboard

KBD This group of outputs is generated from the Keyboard.
PITCH: This is the CV determined by the note that is played on the Keyboard.
VEL: This is the CV determined by the relative velocity
PRESS: This is the CV determined pressure
GATE: This is the gate signal generated when a key is depressed. 

Wheels

WHEELS generated by voyager modulation wheels.
PITCH: This is the CV generated from the Pitch Wheel.
MOD: This is the CV generated from the Mod Wheel.  

Pedal

 This is the output of the Pedal/On Mod Buss. It is the Pedal/On SOURCE shaped by the
SHAPING signal. The level is determined by the
AMOUNT control and the signal at the  MOD1 Input jack

Envelope

This group of outputs is the output of the Envelope Generators.
FILTER: This is the CV output of the Filter Envelope Generator.
VOLUME: This is the CV output of the Volume Envelope Generator. 

Sample and Hold

relative to the Sample and Hold Circuit.
STEP: This is the output of the Sample and Hold Circuit.
SMOOTH: laged Smoothed output 

Multiple and attenuators

VX351
MULT

MULT  two 4-way Mults (aka modular Multiples). A "mult" is used to distribute a single source to multiple destinations.

An example is connecting the Voyager’s LFO to the Volume, Filter and Pan Control Inputs. In  this case, all 3 of those parameters will be controlled simultaneously by the LFO.  

ATTENUATORS are used to reduce the amount of a CV signal. The attenuators have an input jack, an output jack, and a knob. The knob sets the amount of the signal present at the input jack that passes to the output jack. When the knob is set to fully clockwise, the full input signal  passes to the output. When the knob is fully counter clockwise, no signal passes to the output
