INTRODUCTION
Thank you for choosing the Moog" Taurus II Synthesizer.
The Taurus II is a very powerful, unique instrument. It combines a foot pedal control with a versatile synthesizer
featuring a logically laid out front panel and the famous "fat" Moog sound.
This manual serves as an introduction to the instrument and explains the basics of synthesizers using the Taurus II
as a working model. Each of the following three sections takes a different approach to understanding the instrument.
"Trying Out Some Sounds" consists of sound charts which enable you to familiarize yourself with the front panel
and the sound capabilities of the instrument.
"Getting to Know Taurus II" introduces you to each front panel control by way of experimenting with it.
At this stage, you learn how to use the instrument.
"A Closer Look at Taurus II" is a more involved explanation of the Taurus II and explains the basics of the synthesizer.
Once you are familiar with the controls of the Taurus II, you'll be ready to create your own sounds. Part of the
excitement in makingonusic is experimenting with your instrument finding new sounds and new playing techniques.
There is always something else to discover and that's what makes mastering a musical instrument such an enjoyable
continuing experience.

SECTION 3
INITIAL SET UP
Now that you have unpacked the Taurus II, save the shipping cartons and packing materials in case any long distance
transporting is required.
First check to see that you have all the components:
Pedal board
Synthesizer Module
Stand
Power Supply
5 Pin Connector Cable
Gig Bag
Step 1:
Take the stand and carefully screw
Step 2:
Attach the synthesizer module to
Step 3:
Connect the 5-pin connector cable
the end with the larger thread into the
the stand. Underneath the synthesizer module
to the rear of the pedalboard and rear of the
adapter in the center of the pedal board.
there is an adapter which mates with the thread
synthesizer module.
of the stand. The thread is long in order to make
a sturdy connection so several turns of the
module will be required to make a tight fit.
Step 4:
Plugihe 24 volt power supply cord into the POWER IN jack on the rear of the synthesizer module,
plug the other end in the power outlet, then turn on the power switch on the front panel.
AMPLIFIER
Step 5: Using a 1/4" jack audio cord, connect the AUDIO OUT on the rear of the Taurus II to your amplifier
or monitoring system.
Always allow at least 10 minutes for any synthesizer to warm up prior to tuning up.
If no sound is heard, first check that all connections have been made properly.
Check the 5-pin connectors at each end.
Check that the power supply is pushed in all the way in the power outlet.
Check the power-in jack plug, at the rear of the synthesizer module, to see if it is inserted correctly. The power light
above the power-on switch should be glowing.
Check the audio cord by substituting it for another. Alternatively, turn the amplifier volume to a low level,
disconnect the audio cord from the Taurus II and touch the end of the jack plug. If a hum is heard, the cord is O.K.
If you have any problems with the Taurus II, you should first contact the dealer you purchased it from. Any technical
problems usually can be solved by the dealer. Service centers and our own Service Department are also on hand
to assist you. Information on the service center nearest you can be obtained by contacting:

SECTION 4
AMPLIFICATION
To get the best sound reproduction for Taurus II
Taurus II is a powerful monophonic synthesizer. Many of you will use it primarily for bass sounds, however it will produce
a wide range of pitch and tone color just like any other synthesizer. If you are going to use Taurus II for bass synth work only,
a bass amplification system will suffice. However, if you intend to continually use a variety of contrasting sounds, try to use
an amplification system which is designed for synths/keyboards. Your Moog dealer will be able to advise you on this subject.

Taurus II sound charts are line drawings of the instrument's front panel. Positions for placing toggle switches,
rotary controls and sliders are indicated by dots.
To help you remember your own front panel settings (patches) we have included two blank sound charts on page 18.
We suggest you photocopy them to have a supply of blanks. If you create a sound you wish to use again
(especially when you're experimenting or recording) write it down. You'd be surprised how easy it is to
forget that hot patch.

ci Tip
•These sound charts are designed to guide you toward a particular sound. After setting up the patch,
experiment by moving one or two controls. By making several adjustments, you might find a sound you prefer.
Suggested controls to experiment with are:
1. Cutsdff slider in the Filter section. (This controls the brightness of the sound.)
2. Octave switch in the Oscillator section. (This switch selects the overall pitch of the instrument.)
3. Attack and Decay sliders in the Contour Generator. (These control the rise and fall of the loudness
and the filter.)
O.K. You're eager to start playing the Taurus II. Set up these patches and get an idea of the many sounds
Taurus II can produce.

Moving the Pitch Wheel just small amounts can bend the pitch in subtle expressive ways. Small pitch glides
can also be achieved using the Pitch Wheel. Even rocking the Pitch Wheel around its notched central
position can produce interesting modulation of pitch. Large continuous movements of the Pitch Wheel
will create sound effects.
You can even transpose melody lines by leaving the wheel set at a desired interval.

A CLOSER LOOK AT TAURUS II
How are the functions of Taurus II organized?
The best way to think of any synthesizer's functions is to think of the whole thing as a modular instrument.
A module may best be defined as an individual part that has its own special purpose. To understand and use
a synthesizer correctly, you need only to understand each of its modules. The "connecting" of one module
to another is easily done with the switches and controls on Taurus II.

To begin with, there are four basic modules on every synthesizer:
1. Audio Generators (oscillators, noise generator)
2. Modifiers (filter and modulation sections)
3. Articulators (contour generator and voltage-controlled amplifier)
4. Performance Controllers (pedalboard, pitch bend wheel)
What are audio generators?
The audio generator portion of Taurus II consists of two oscillators and a noise generator. The oscillators
produce electrical waveforms with variable shapes and frequencies that you can control for different
tone colors or pitches. The noise generator produces a non-pitched signal that can be used for percussion,
wind or surf-like sounds and many other effects.
Both oscillators produce sawtooth waveforms (
wave (
|~LJ
/[/]/
). Oscillator one also produces a square
) and oscillator two produces a narrow pulse wave (
fl
I
)•
The octave switch provides a 3-octave range for both oscillators. In addition, oscillator two may be
tuned up to one octave higher than oscillator one.
The "detuning" of oscillator two is done by first switching the SYNC switch OFF, then turning the
INTERVAL knob to the desired position.
When the SYNC switch is turned ON, the pitch of oscillator two will be locked in synchronization
to that of oscillator one.
When the SYNC switch is turned to CONTOURED, the settings on the contour generator will change
the spectrum of oscillator two. However, since the two oscillators are locked in synchronization,
this frequency sweeping will cause a rapid change in the output waveform, creating unusual "screaming"
effects. This is a unique sound on Taurus II; it can be heard clearly on the Bass III Sound Chart on page 8,
and the Bass VII Sound Chart on page 11.

What are the modifiers?
There are two types of modifiers used on Taurus II, and since each has a very separate purpose,
it would be best to look at them one at a time.
1. Filter
This module changes the tone color of the sound produced by the audio generators. It does so by adding
or reducing the amounts of high frequencies present in the signal. This is controlled by the CUTOFF slider.
In addition, EMPHASIS may be added to increase the effect of the filter's function, and the CUTOFF can be
controlled further by the pedalboard and contour generator. EMPHASIS amplifies a narrow band of frequencies
surrounding the cutoff point.
Raise the AMOUNT slider to increase the effect of the contour on the filter CUTOFF.
The KEYBOARD TRACK control may be adjusted from "0" (no effect of the notes played on the pedalboard
is heard in the filter) to "1" (full control of the filter by the pedalboard).
A great many unusual tone colors may be produced using the filter, and a complete understanding of its function
will give you control over an almost infinite variety of musical sounds.
33
• V f -»
2. Modulators^
Modulation means change. The use of the modulators will give you unusual changes in the outputs
of the audio generators or filter. As the performer, you will be able to control the amount of these changes,
the speed of the changes, and the portions of the synthesizer that may be affected by these changes.
The modulation section of Taurus II provides such effects as vibrato, tremolo, automatic repetition and
sample-and-hoid
The actual modulation is produced by a low-frequency oscillator (LFO) built into Taurus II. You can control
its repetition rate with the RATE knob and its waveshape with the 3-position SHAPE switch.
You may then select to apply this modulation effect to either the two oscillators for vibrato or
the filter (VCF) for tremolo, or both, •
Note: The amount of modulation (amplitude) is controlled by the MOD WHEEL. If the wheel is in
its lowest position, no modulation effects will be heard.
AUTO TRIGGER will trigger the contour generator at each complete cycle of the LFO when turned ON.
For sample-and-hold patterns, select the RANDOM (
"r[/r ) shape, turn AUTO TRIGGER to ON,
route the modulation to OSC and/or VCF and raise the MOD WHEEL fully.

35
What are artictfjators?
The articulators are those portions of a synthesizer that allow the musician to control the loudness of the instrument,
the duration and shape of each tone, and the phrasing desired. On Taurus II, the contour generator controls
articulation. It is put into operation each time you depress a pedal on the pedal board or when triggered by the
AUTO TRIG function.
Sliders allow control of both the attack and decay times. These may be set from fast (0) to very slow (10). *
A SUSTAIN switch holds maximum loudness while a key is depressed.
The contour may be used to control the filter cutoff. This effect is created by raising the AMOUNT slider
in the Filter section.
A 3-position switch labeled VCA MODE applies the contour directly to Taurus ITs amplifier in position 1,
in center position allows the amplifier to be turned ON and OFF by the pedalboard alone, and leaves
the amplifier ON at all times in position 3.
♦Specific attack and decay times are listed in Taurus II Specifications in the back of this manual.

What are the controllers?
The two primary controllers on Taurus II are the pedalboard and the pitch wheel. Each of these
will change the frequencies (and therefore the pitches) of the oscillators in the audio portion.
The pedalboard can also be used to alter the cutoff of the filter. This is controlled by the KEYBOARD
TRACKING knob on the filter section. The pedalboard is also directly connected to the articulation
portion of the instrument so that pitch and articulation are controlled simultaneously.
A GLIDE control allows theaddition of portamento (sliding from note to note) when playing on the pedals.
The speed of the glide is adjustable.
The TUNING knob controls both oscillators simultaneously.
The MIXER allows different levels of each oscillator and/or noise to be combined into the final output
(MASTER VOLUME control).
Note: When placed at the upper level (7.5 - 10) the mixer will automatically go into overdrive.
This is a distortion circuit built into the instrument. Overdrive creates a driving sound similar to,
but less dramatic than, that of a fuzz box or other guitar processors. It also helps to create a fatter sound.
For normal oscillator sound set MIXER at approximately 5.

INTERFACING
Taurus II has a number of connectors on the rear panel which can be used to interface Taurus II with synthesizers,
sequencers and other instruments which are voltage controlled.
Interfacing can work in both directions. Taurus II can control or be controlled by another instrument. When interfacing
a Taurus II with another instrument, two connections are normally required: a control voltage (CV) and a trigger or gate.
EXAMPLE 1:
Interface a Taurus II to a Source.
Taurus II would be the master, the Source the slave.
Reason for interface: bigger sound because of two synths playing plus programmability of The Source.

The Liberation's control voltage output must be scaled and ranged. Scaling makes sure intervals are correct
on both instruments and ranging ensures unisons are correct. The proper procedure is as follows:
1. Check that the Taurus II is in tune with Liberation.
2. Make all interface connections.
3. Set volume of Taurus II and Liberation so you can hear both instruments clearly.
4. Depress top C on Liberation and adjust range until Taurus II is in tune with Liberation (zero beats).
5. Play low F on Liberation and adjust scale so both instruments are in tune (zero beats).
6. Repeat steps 4 and 5 until perfect tuning is obtained.
The two interface controls contain all control voltages necessary for performance. The voltages for the ribbon, force sensor,
modulation and keyboard are all summed together, so the slave instrument now becomes as versatile as Liberation.
41
EXAMPLE 3:Mnterface a RS-09 Roland Synth with a Taurus II.
Taurus II would be the slave, the RS-09 the controller.
Reason for interface: to use the strings and organ of the RS-09 and produce a brass sound via the Moog filter.

CONTROL VOLTAGES
The CV supplies information about pitch, e.g., the higher the voltage the higher the pitch. Moog synthesizers
use a CV of 1 volt per octave. Many other manufacturers use this system.
Control voltages enter and leave Taurus II at the synthesizer module In/Out connector which is a stereo jack.

INPUT
TRIGGERS
A trigger/gate sends a signal which turns ON or OFF the Contour Generators of an instrument.
Moog has customarily used S-triggers (switch triggers).
When an S-trigger occurs, the voltage (around 12 volts) goes from +12 to ground. Acting as a switch in the circuit,
this causes the Contour Generators to turn on.
Taurus II also has a V-trigger otherwise known as a gate. A V-trigger occurs when the voltage (at 0 volts)
goes from 0 to +10 volts. Taurus (I will accept input voltages from +3v to +10 volts as V-triggers.
TRIG IN/OUT

Example only. The wiring of these jacks will depend on the connector they are
being plugged into. Refer to a wiring diagram, if available.
AUDIO IN
Any audio signal can be processed by Taurus ITs filter section. (The Audio IN connector routes the signal
to the filter.) The signal impedance level should be around 18K. Most HI LEVEL audio signals
are within this general range.
The Taurus II filter will act as a sophisticated tone control. When the bypass switch is ON, the filter
is controlled by manually adjusting the CUTOFF, EMPHASIS or AMOUNT sliders. Alternatively, with the
VCA Mode switch in CONTOUR, the filter can be controlled by depressing a pedal and using the ATTACK
and DECAY controls to open and close the filter. Modulation of the filter can also be introduced via the
MODULATION WHEEL.
Patching a guitar through the AUDIO IN will enable you to control the tone color, but will not cause Taurus II
to play. A pitch to voltage device would be required to achieve this.
Using the AUDIO IN can produce some very interesting effects in conjunction with CV and Trig; e.g., utilizing
the Moog filter with a Roland RS-09.
45
EXAMPLE:.*,
1 • Take the GATE OUT from the RS-09 and connect it to the V-GATE IN
of the Taurus IL
2. Route the Audio Output of the RS-09 through Taurus II via the AUDIO IN.
3. Set the OSC 1 and OSC 2 sliders of Taurus 11 to 0.
4. Play the R5-09.
Remember that envelopes of both instruments will be functioning. The envelope with the shortest
cycle will dictate when the sound ceases. Therefore, long decay, sustain and release times
work best with this example.
When the RS-09 is played, it will control the VCF of Taurus II. Result, the RS-09's audio signal
will be passing through the Moog filter, with its full contouring control and the famous Moog sound.
COMPATIBILITY OF CONTROL VOLTAGES
The CV in Taurus II comes from the pedalboard. The bottom pedal is 0 volts, the top pedal
will give 1.5 volts.
If the bottom note of the instrument being interfaced to the Taurus II is C, only a small scale and range adjustment
will be necessary to match both instruments. In most cases, it is the slave instrument that should be recalibrated.
For bottom notes which are other than C, larger adjustments or modification may be required.
Refer to a Service Manual or consult a Moog Dealer or Service Center for correct retuning procedures for
interfacing.
