OVERVIEW AND FEATURES

The Minitaur is a monophonic Analog Bass Synthesizer with a 100% analog audio
path. It is based on the legendary Taurus I and Taurus 3 Synthesizers. The Minitaur
features 2 ultra -stable voltage controlled oscillators, a genuine M oog low pass
filter, 2 envelope generators and a modulation circuit. The Minitaur has a classic
one knob per functi on design in a rugged performa nce package that is s mall
enough to take with you anywhere.

BACK PANEL

SIGNAL FLOW

To understand how the Minitaur generates sound, take a look at the diagram
below. It shows the flow of Audio, Control Voltage and Modulation signals in
the Minitaur. Heavy lines indicate audio signals, which flow from left to right.
Lighter lines indicate Control Voltages (CV’s), which flow from the top and
from the bottom. Dotted lines indicate Modulation routings.

The Minitaur’s source signals are created by two Voltage-Co ntrolled Oscil­lators (VCO) which are mixed with the External Audio I nput. The Mixer
Output is routed to the Filter, where the ton e is sculpte d according to th e
Filter pa rameter s and the Fil ter AD SR Envelope. Th e signal is then passed
to the Amplif ier ( VCA) stag e, where the Volume ADSR envelo pe shapes it.
Finally, the signa l is rou ted to th e Output se ction, where

the final level is

set by the Volume control knob.

For most users, MIDI will be the main source of control for the Minitaur. Each
time the Minitaur receives a MIDI “Note On” command, it produces a Pitch CV
and Gate signal in response. The Pitch CV signal sets the Pitch of the Oscillators,
while the Gate signal triggers the Filter and Volume ADSR Envelop es.

The Mi nitaur can also be oper ated vi a CV and G ate trigger co nnections ,
for a mo re ‘old school ’ meth od of control . Both control meth ods (MIDI &
CV/Gate) can be used at the s ame time, altho ugh s ome combinations of
control signal s may ca use unpredictable results .

BASIC OPERATION

The Minitaur responds to MIDI messages on both DIN and USB MIDI Inputs.
In addition, Minitaur’s knobs and switches transmit MIDI Control Change
(CC) commands via MIDI USB, allowing parameter adjustments to be
captured by any MIDI-recording device. Minitaur has an LED MIDI indicator
that indicates MIDI activity on either the DIN MIDI or USB MIIDI connector.
To further extend the Minitaur’s capabilities, there are additional parameters
that can be accessed via MIDI control. A complete list of all MIDI CC commands
can be found on page 22-23.

The frequencies of both Oscillators are affected by a number of sources. The
main source is a ‘Note On’ command transmitted from an external MIDI
controller or DAW. The ‘Note On’ command is translated into a Control
Voltage that allows the Oscillators to be played in an equal-tempered scale.
Other control sources include Minitaur’s GLIDE circuit, VCO 2 FREQ, the
PITCH CV INPUT, the FINE TUNE control, and the output of the MODULATION
(LFO) circuit. The highest pitch produced by Minitaur’s Oscillators is C5
(523.25 Hz) or MIDI note value 72.

PANEL CONTROL S FOR THE OSC ILLATOR

OSCILLATOR 1 Switch (CC# 70):
Select s a Sawtooth (LED OFF ) or Squ are wave (LED ON) for VCO 1.

OSCILLATOR 2 Switch (CC# 71):
Select s a Sawtooth (LED OFF ) or Squ are wave (LED ON) for VCO 2.

VCO 2 FREQ (CC# 17):
Sets the freque ncy of fset of VCO 2 from VCO 1. The offset range is +/-1
octave. Center position tunes VCO 2 in uniso n with VCO 1. NOTE: If playing

between notes 60 and 72, the pitch of VCO 2 is limited to note 72 (C4)
regardless of this control setting.

The Oscillators are the main sound source of Minitaur.
They create electronic vibrations that can be tuned
and amplified into sound that we can hear. The
Minitaur’s VCOs can produce a total musical range
of 6 octaves.

OSCILLATOR 1 (VCO 1) serves as a master Oscillator
to which OSCILLATOR 2 (VCO 2) is tuned. Two
independent switches select the waveform for
each Oscillator (Sawtooth or Square). A FINE TUNE
control adjusts the master tuning of both Oscillators.

FINE TU NE:

Adjusts the freque ncy of both VCOs by approximately +/-1 semitone. The
FINE TU NE control does not transmit M IDI.

MIDI ACCESSI BLE CONTROL

VCO 2 BEAT (CC# 18):
Select s the fine freque ncy offset for VCO 2 . The adjustment range is
+/- 50 cents.
Default = 64.

NOTE SYNC (CC# 81):
When enabled, NOTE SYNC forces both oscillators to s tart at the same
time, eliminating a ny phase differences at the start of each “ Note On”
command . This ensures energy is consistent at th e start of each new note.
Default = OFF.

EXTER NAL CONTROL

The PITCH CV jack on the back pane l is a CV input for external control of
the Oscillator pitch. This input controls the fre quencies of both Oscillators.
A 1 volt change of this voltage will change the pitch by one o ctave. The
jack acce pts 0 to +5 volts, or an expression pedal like the Moog EP-2.

PERFO RMANCE TIPS:

• For punchy bass lines, try using NOTE SYNC to keep the
energy at the beginning of each note the same.

• A steady control voltage applied to the PITCH jack will
offset the base pitch of both oscillators. You can use this
feature to transpose the oscillators to any desired interval.

• To recreate the classic Taurus sound, choose the Sawtooth
wave for one or both oscillators.

The FILTER is a classic Moog 24dB/
Octave Low-Pass Filter design with
resonance. It has controls for CUTOFF
frequency which determines the range
of frequencies the filter will affect, as

GLIDE (AKA ‘portamento’) is a musical effect that makes smooth
changes in pitch between notes. The Minitaur’s GLIDE RATE is
adjustable from instantaneous to extremely long.

GLIDE

Each Oscillator (VCO 1 & VCO 2) has a dedicated level
knob that allows you to control the relative strength of
each oscillator from 0 to 100%. NOTE: The VCOs begin

to clip the filter at about 2 o’clock creating more
agressive sounds.

the same regardless of the interval. When LCT is selected, the GLIDE TIME stays
the same regardless of the interval. When EXP is selected, the GLIDE RATE follows
an exponential curve that starts fast and then slows as it approaches the target
note (like the Taurus).
Default = LCR.

LEGATO GLIDE (CC# 83):
Normally, GLIDE occurs with every new note. When LEGATO GLIDE is enabled,
however, GLIDE is only applied when a new note is received while another note
is still being held.

ENVELOPE GENERATORS (EGs) add motion to
a sound after a note is played. The Minitaur has
two separate Minimoog style Envelope Genera­tors that affect the brightness and loudness of
the Minitaur's sound by modulating the Filter
Cutoff (VCF) and Volume (VCA).

The EGs are started by a Gate or MIDI
Not e message. Once started, their
shape in time is set by th e ATTACK,
DECAY/RELEASE, and SUSTAIN controls,
as well as the Release switch and length
of the Note played.

MODULATION is an important part in the crea­tion of musically-expressive sounds. The Minitaur’s
MODULATION section provides an LFO with adjustable
RATE and AMOUNT controls for the oscillators

(VCO) and the Filter (VCF). The Low Frequency
Oscillator (LFO) is a signal used to move the pitch of VCOs and the Filter Cutoff
up and down automatically. A LFO can be used to simulate vibrato, create
wobbling filter sweeps, or make interesting synthesizer sounds.

EXTER NAL CV CONTROL

The GATE jack on the back panel is a trigger input that accepts a +5V G ate

triggering via M IDI. You will still be able to control the Osc illator pitch and
Mo du latio n a mounts from a M I DI co ntro ll er, bu t the envelo pe s will not

The RELEASE switch enables or disables the Release segment of
both Envelope Generators. When enabled, the Envelope Release
time is the same as the Envelope Decay time, and the DECAY

control adjusts the time for both segments. When disabled, the
Release segment does not occur and the Envelope stops abruptly in response
to a “Note Off” message (or when the Gate CV goes to zero).

PERFO RMANCE TIPS:

• You can use the Minitaur to process any audio signal simply

by plugging into the AUDIO IN jack. To hear the external
audio signal, you will need a MI DI NOTE ON message. To
hear the external audio signal without issuing a M IDI NOTE
ON message, apply +5V to the GATE jack. This will leave
the Gate open, and the A mplifier Envelope will remain at
its Sustain level until the Gate closes .

• The M initaur’s audio input is not limited to processing
monophonic sig nals - it can work well for processing
polyphonic signals, too. For example, connect the Audio
Output of a MIDI-e quipped polyphonic keyboard to the
Minitaur’s AUDIO IN jack, and turn the MIX level of VCO 1
and VCO 2 all the way down on the Minitaur. Now you
have a polyphonic source affected by the M initaur’s
Filter and Envelope circuits - a great way to warm up a
sterile digital signal!

MIDI CO NTROL CHANGE (CC) MESSAGES

The tables on the followin g pages list all MIDI CC message s f or the

Min itaur. Messag es shown with an (M) indicate paramet ers which are
only accessible via MIDI. Bolded values indicate the appropriate range
for 7-bit mess ages (MS B).

NOTES :

•

The Minitaur sends 7-bit MIDI CC messages for all parameters.

It can receive eith er 7-bit o r 14-bit values f or the par ameters

controlled by knobs, but only 7-bit values for parameters con­ trolled by switches.

• For all parameters, the MSB indicates the ‘regular’ CC number,
and the LSB indicates the high-resolution ‘ fine’ control value.
If you are only sending 7-bit MIDI CC messages to the Minitaur,
use the MS B n umbe r by it self. N ot e th at w he n MSB -o nly
messages are issued, the value range is always 0-127.

A NOTE ABOUT CONTROL PARAMETERS

LOCAL CONTROL OF F (CC# 122):
This parameter allows the front panel controls to send MIDI, but disconnects
the Minitaur sound eng ine fro m direct control by the panel. Per the MID I

spec, only values of ‘0’ and ‘127’ work (0 = OFF, 127 = ON). If you are conn­ected to a DAW using U SB MIDI pa tched thro ugh, you may n eed this to
avoid feedback artifacts. After changing the state of LOCAL CONTROL
on/off, the Minitaur remembers th e last setting after power down.

ALL SOUN DS OFF/ALL NOTES OFF (CC# 120 or 123):
Both of these parameters are MIDI ‘panic’ functions that are used to silence
hung MID I notes. Controllers or DAWs may send one or the other command

which is why the Minitaur will respond to either.

COMPL EX TIMBRAL MO DULATION

1. Using a 1⁄4” patch cable, connect the CP-2 51 LFO Triangle
output to an Att enuat or Input

2. With another 1 ⁄4” patch cable , connect the At tenuator
Output to the M initaur’s FILTER CV jack.

3. On the Minitaur, set the LFO RATE contr ol and the VCF
LFO AMOUNT c ontrols to the 12 o’c lock position.

On the CP -251, set the LFO Rate c ontrol to 1 o ’cl ock an d adjus t the
Attenua tor t o +3 on the dial . This will result in a co mplex modula tion
effect as the Filter Cutoff Frequency is modulated by both LFOs. Setting
the LFO ra te s c onsidera bly higher w ill r es ult in e ven wilder timbr al
texture s, while very lo w settings will cre at e slowly evo lving complex
filter sweeps. For a “random stepping” filter effect, use the S&H Out 1
in plac e o f th e LFO Triangle out .

Using the multiple jack on the CP-251, you can simultaneously route the
LFO or S&H modul ation signal to the Minitaur’s Pitch, Filter and Volume
inputs all at once, or split the modulation signal using the multiple jack and
route it into both Attenuators to have two controllable modulation sources.

WE’VE JUST SCRATCHED THE SURFACE

Other CV-equipped gear like our Moogerfooger analog effects can be used
to expand the sonic potential of the Minitaur. We encourage you to experiment;
whether you are trying to create an original sound or duplicate an existing
sound, experimentation is part of the fun!

28

APPENDIX C - CARING FOR THE MINITAUR

Clean the Minitaur with a soft, slightly moist cloth only – do not use solvents
or abrasive dete rgents. H eed the safety warni ngs at the beginning of the
manual. Don’t drop the unit. If you are shipping your Minitaur to the factory
for servicing, we recommend using the original shipping carton, or an ATA
approved Road Case.

AN IMPO RTANT NOTE ABOUT SAFETY: Do not open the chassis. There are
no user serviceable parts in the Minitaur. Maintenance of the Minitaur
synthesiz er should be ref err ed to qualified serv ice personnel only.

APPENDIX D - USING THE CP-251 WITH THE
MINITAUR

Th e Moo g CP -251 C ontro l Pr o ce s sor mak es an ideal c ompanion to
the M in itaur. It provides an LFO with two wave forms (Triangle/Square),
a S a mple & Hold circuit with tw o outputs (S tepped/Smoo th ) , a Lag
Proces sor, Noise source , and a Mixer and two At tenua tors. The CP-251
greatly expands the sonic palate of the Minitaur, allowing for the creation
of n ew sonic texture s.

Here are some possible co nfigura tions for using the CP- 251 with the
Min itaur. Grab som e patch cor ds and try these sugges tions!

NOISE AS AN AUDIO SOURCE

You can use the CP -251 Noise source a s an audio source t o add inter­es tin g artif acts to an e xis ting sound (for ex ample , cre a tin g th e
illusion of ‘bre ath’ ) or proces s the noise jus t b y itself to crea te snare,
win d, and surf sounds. Simply route the CP-251 Noise output through
an atte nuator and then into the Minitaur’ s A udio In jack. Noise nev er
sounde d so good!

NOISE AS A CONTROL VOLTAGE

You ca n use the CP-25 1 Noise sour ce a s a C ontr ol Voltage by simply
routing it to any of the Minitaur’s CV inputs (PITCH, FILTER and VOLUME),
but a better me thod is to rout e the Noise through an A tte nu ator first:

1. Using a 1⁄4” patch cable, connect the CP-251 Noise output
to an Attenua tor input.

2. W ith anot her 1 ⁄4” pat ch cable, connect the At tenua tor
output t o one of the Minitaur ’s CV jacks.

This will allow you to raise or lower the Noise level as desired, adding
jus t a touch of noise t o add realism to a sound, or a blast of noise for
extreme sonic effect.

PRESETS

Minitaur can now store up to 100 presets in internal memory. Presets can be
saved and loaded using the Minitaur REV 2 Editor, or via any sysex utility.

TO SCROLL THROUGH PRESETS FROM THE FRONT PANEL:

While holding the GLIDE button, press the VCO 1 button to increment
presets or press the VCO 2 button to decrement presets.

Hold the GLIDE button and press both VCO 1 and VCO 2 buttons to return to
panel mode (Preset 0).

DECAY/RELEASE CONTROL

REV 2 introduces a new operational mode for the Envelope DECAY/RELEASE knobs.

DECAY AND RELEASE MODES

To toggle between Mode 1 and Mode 2 press and hold the RELEASE switch
for 1 second. The RELEASE switch LED will blink one time to indicate Mode 1,
or two times to indicate Mode 2. (The selected mode is remembered on

power-down).

MODE 1 - Control of DECAY and RELEASE functionality is linked.

MODE 2 - Turning the DECAY/RELEASE knob by itself adjusts DECAY time.

To adjust the RELEASE time, press and h

old the RELEASE switch while

turning the DECAY/RELEASE knob.

NOTE: The Release On/Off function is now toggled when the panel button
is released.

CV MAPPING

In REV 2 , the PITCH, VOLUME, and GATE Controller Inputs on Minitaur can be
re-mapped to control other parameters. This allows you to use control voltage
in new and creative ways.

The PITCH and VOLUME inputs provide continuous control, like the panel knobs,
while the GATE input only provides on/off type control. Therefore, the PITCH
and VOLUME inputs can be re-mapped to any parameter, while the GATE input
can only be used to control two-state parameters (on or off).

CV Mapping is configured in the Minitaur Editor/Librarian software on the

Hardware Settings panel (Ctrl/command+3 to display). There is a CV Mapping
menu for PITCH, VOLUME, and GATE. Simply click any item on these menus to
select a new destination.

NOTE: CV Mapping settings are global; they do not change per preset and are
saved on power down. To reset all Controller Inputs to default settings, simply
click the Default Mappings button on the Minitaur Editor Hardware Settings panel.

MINITAUR REV 2 ADDENDUM

CV TO MIDI CONVERSION

Minitaur can now convert multiple channels of Control Voltage to MIDI! This
allows you to take CV sources such as modular synths, a CP-251 Control Proces-
sor or a Moog Etherwave Pro Theremin, and translate the voltage into MIDI
control for your plug-in effects, soft synths, or other MIDI gear.

All Minitaur sound parameters have an assigned MIDI CC number. When a
parameter value changes, Minitaur sends out MIDI CC data over its USB MIDI
connection. When one of the Controller Inputs is mapped to a non-default
parameter, Minitaur will send out CC messages for that parameter in response to
control voltage changes at the input.

In order to get optimal response from the CV to MIDI conversion, you will need
to adjust the scale and range of the control voltage to stay within the range of 0
to +5 Volts, before applying voltage to the Controller Input.

WARNING: Do not apply a negative control voltage, or a CV greater

than +5 Volts.

MINITAUR REV 2 ADDENDUM

LFO SYNC PHASE RESET

LFO Sync Phase Reset in the Minitaur REV 2 Editor is labeled LFO Phase Reset.
This parameter affects the LFO behavior while it is synced to MIDI. If LFO Sync
Phase Reset is ON, then the LFO waveform is reset to the start of its cycle on the
beginning of every “beat” according to the current MIDI clock settings. Since
the LFO rate is set to give one cycle per “beat”, this Phase Reset is usually
inaudible, as it lines up with where the start of the cycle should already be. This
reset corrects for clock inaccuracies that could otherwise cause the LFO to drift
relative to the beat.

NOTE: If you sweep the LFO Rate knob while in MIDI sync, this can cause abrupt
and noticeable jumps in the LFO if it is reset mid-cycle. If LFO Sync Phase Reset
is OFF, then you can sweep the LFO Rate while in MIDI Sync, however you may
find that the LFO cycle drifts relative to the beat.

KNOB MODE

This parameter controls the behavior of Minitaur’s panel knobs when their
physical position does not match the associated parameter value, which often
happens when changing presets. In SNAP MODE, as soon as the knob is moved,
the parameter value jumps to the current knob position. In PASS-THRU MODE,
turning the knob will have no effect on the sound until the knob position
matches (“passes through”) the parameter value, after which the knob behaves
as normal. In RELATIVE MODE, turning the knob adjusts th

e parameter value

proportionally, so that there are no sudden jumps in value.

LOAD PRESET MOD WHEEL VALUE

If On, loads a saved Mod Wheel value on preset load (the Mod Wheel value that
was active when the preset was saved). If Off, then the “live” / current Mod
Wheel value persists when changing presets.
