INTRODUCTION
The Memorymoog is a voice-assignment polyphonic synthesizer with the ability to store up to
100 patches in computer memory. It has six independent voices, each containing three voltage-con-
trolled oscillators, a voltage-controlled 24dB/octave lowpass filter, two ADSR contour generators,
and extensive modulation facilities. This means that there are 18 oscillators, six filters, and 12 con-
tour generators in the unit. However, there is a single set of controls for those components, meaning
that their sound is programmed homophonically - each program governs each voice identically.
At the heart of the Memorymoog is the System Controller which gives you command over the
instrument's microprocessor. With the System Controller you can change programs, store patches,
change keyboard modes, use the cassette interface, alter arpeggiation mode, and set up program se-
quences. Learning to use the System Controller is the key to learning how to use the Memorymoog.
This manual is designed in sections, starting with a quick setup guide for those of you who are
in a hurry to quit reading and start playing. It tells you some dos and don'ts about setting up and ex-
plains what you'll need to know about the System Controller in order to get at the programs.
Section II is a reference guide designed to help answer any questions regarding specific features on
the Memorymoog. Section III is a step-by-step explanation of each set of controls for those of you
who aren't all that familiar with synthesis. It's designed to help clarify things that may seem vague in
Section II. The final section of the manual deals with service information and contains schematics
and maintenance details. A sound chart section is included that contains diagrams of all the factory
programs. Some blank panel diagrams are also provided for you to copy down your own patches.

SECTION I
SETTING UP
If you haven't bought a flight case for your Memorymoog, save the carton it came in in case you
have to arrange long distance transportation.
After unpacking your instrument, hook it up to a wall socket by first inserting the detachable
three-pronged cord into the back of the Memorymoog and then into the power outlet. Be sure that
the outlet is putting out the right amount of voltage.
110V = USA
220V = EUROPE
If you want to operate your Memorymoog on a voltage that differs from what's coming out of
the wall socket, i.e. 220 instead of 110 or 110 instead of 220, an authorized Moog service center can
set up your instrument to operate at the proper voltage.
Next hook any footpedals or switches you desire to use up to their respective inputs. Then con-
nect the audio output of the Memorymoog to an amplification system using either an XLR cable or
a 1/4" phone jack. A high quality amp is desirable due to the wide frequency range of the Memory-
moog. Also, note that different amps will make the programs sound different.
Turn the output volume of both the Memorymoog and the amp down to zero. Turn the Memory-
moog on and then turn the amp on. Bring the volume of the amp up to where you're used to setting
it. While holding down a note, bring the MASTER VOLUME control (at the upper right corner) up
until it's at a comfortable level.

6 TUNED
After you've turned the instrument on, let it warm up for about 10
minutes to allow the oscillators to stabilize. Then hit the AUTO TUNE
control in the upper left-hand corner. This will tune the Memorymoog's
18 oscillators. Notice that the SYSTEM CONTROLLER's Alphanu-
meric Display reads "6 TUNED" after the tuning cycle is complete, in-
dicating that all six voices have been tuned. If a number less than six
appears in the screen, it means that the system was unable to tune one
or more of the oscillators for some reason. Try hitting the AUTO
TUNE switch again if this occurs. If they still fail to tune, they can be
manually disabled. Refer to the Service Section of the manual for de-
tails.
CALLING UP PROGRAMS
When you first turn the Memorymoog on, program Number 1 will
appear in the PROGRAM DISPLAY window of the SYSTEM CON-
TROLLER. To change program numbers, hit any number from 0 to 99
followed by hitting the ENTER button on the Numeric Keyboard of the
SYSTEM CONTROLLER.
EDITING A SOUND
Changing or editing programs is very simple. If you want to alter
some aspect of any of the sounds supplied by the factory, all you have
to do is hit any of the switches (except those in the SYSTEM CON-
TROLLER) or hit any of the rotary controls (pots). You'll notice that
when you hit a switch the Alphanumeric Display will read "EDIT," and
when you turn a pot, six numbers appear in the display screen.
The group of three numbers on the left indicates the value of the pot as
it is in the program memory, and the group of three numbers on the
right indicates the current value of the pot.
Hitting the ENTER button will immediately restore the program
values.

CALLING UP AND STEPPING THROUGH PROGRAM SEQUENCES
To get into the PROGRAM SEQUENCE MODE hit PREFIX letter D, followed by any number
from 0 to 9, followed by ENTER. This gets you to one of the 10 PROGRAM SEQUENCES. What
will appear in the Alphanumeric Display looks like this:
The number in the PROGRAM DISPLAY is the first program of the PROGRAM SEQUENCE.
The B at the left of the screen indicates the beginning of the SEQUENCE. As you step through the
SEQUENCE, the number that appears in this spot indicates the previous program number. The cen-
ter of the display shows the PROGRAM SEQUENCE number, and the number to the right of the
screen is the program number next in line in the SEQUENCE.
To step through the PROGRAM SEQUENCE, use the A PREFIX switch to go forward and
the B PREFIX switch to go backward. You can also use PROGRAM ADVANCE and PROGRAM
BACKSTEP footswitches for these functions. (Note that the footswitches aren't supplied with the
instrument.)
Experimenting with the programs, editing them, and stepping through the PROGRAM SE-
QUENCES should keep you busy for at least a few minutes. It should also start generating questions
about other features on the instrument. Section II of the manual provides brief descriptions of all the
various functions of the Memorymoog, while Section III offers step-by-step explanations. From this
point, refer to those sections as the need arises.

1.0 KEYBOARD/PERFORMANCE CONTROLS.
1.1 AUTO TUNE.
Touching this switch causes the computer in the unit to tune the
18 oscillators. Tuning takes about 8 seconds. The instrument
will be "dead" for that period of time. The SYSTEM CON-
TROLLER's (3.0) Alphanumeric Display will show "TUNING"
when the switch is initially depressed, and it will show how
many voices have been tuned at the end of the tuning cycle.
1.2 TUNE.
Lets you fine tune the instrument over a range of ± 3 semitones.
This is a non-programmable control and will affect all voices
identically.
1.3 MONO.
This switch puts the instrument into the monophonic mode - it
will play only one key at a time. The number of voice cards you
control is variable from I up to 6, giving you control over from
1 to 18 oscillators. This is programmed by the SYSTEM CON-
TROLLER (3.0) and the MIXER section (7.0).
1.4 MULTIPLE TRIGGER.
When on, the keyboard triggers all contours when any new
keys are depressed. When off, new notes trigger only the as-
signed voice.
1.5 KB OUT.
KEYBOARD OUT controls the trigger and voltage outputs
from the EXTERNAL SYNTHESIZER OUTPUT section
(14.0). It's used when controlling an external synthesizer. When
on, the Memorymoog will control the external synthesizer.
1.6 GLIDE AMOUNT AND GLIDE ON/OFF.
The glide is both monophonic and polyphonic. When the in-
strument is in mono mode, a master glide circuit takes over for
the 6 separate glide circuits that work when it's in polyphonic
mode, and allows the instrument to glide in unison. Glide is
linear. Maximum glide time between the outer notes of the key-
board is about 10 seconds.

SECTION II
This section of the Memorymoog manual is designed to answer questions about the function of each
control on the front and back panels of the instrument. It's a quick reference guide; more detailed
explanations will be found in the next portion of the manual.

6
1.7 KB MODE.
KEYBOARD MODE affects the priority of the
keyboard when it's in both mono and polyphonic
modes. In mono mode, the SYSTEM CONTROL-
LER (3.0) Alphanumeric Display shows either
"MONO 1, 2 or 3," depending on the mono mode
programmed. Mono 1 is last-note priority, Mono 2
is low-note priority, and Mono 3 is high-note pri-
ority. In polyphonic mode, the Alphanumeric Dis-
play will show either "POLY 1" (cyclic), "2" (cy-
clic with memory), "3" (reset to voice A), or "4"
(reset to voice A with memory). Voltages routed
to an external synth via the EXTERNAL SYN-
THESIZER OUTPUT (14.0) are affected by this
control.
1.8 HOLD.
Lets you build up chords and transpose them in
parallel motion from the keyboard. Holding a
chord and then pressing the HOLD button will
memorize the chord. Holding down the HOLD
button and then pressing notes on the keyboard
will let you build widely spaced chords. Releasing
the HOLD button memorizes the chord. The chord
can then be transposed from the last note you
played on the keyboard.
1.9 ARPEGGIATOR.
Continuously triggers note played on the key-
board. Rate is set by the LFO (5.0) speed. The
Clock can be overridden by an external trigger
source at the CLOCK IN (15.5) on the back panel.
The internal clock is reset by the keyboard so you
can always play in time. The Arpeggiator operates
in six different modes:
1) Plays back notes from bottom to top, un-
latched (notes stop when you lift off the key-
board).
2) Plays back notes from top to bottom, un-
latched.
3) Plays back notes from top to bottom, and then
from bottom to top, unlatched.
4) Plays back notes from bottom to top (latched).
The notes will continue if you lift your hands
off the keyboard.
5) Plays back notes from top to bottom, latched.
6) Plays back notes from top to bottom, and then
from bottom to top, latched.
1.10 PITCH BEND AMOUNT.
Lets you vary the maximum range of the
PITCH BENDING WHEEL (2.2) up to
± 1 octave. Note that this control is pro-
grammable.
1.11 MODULATION AMOUNT.
Sets a programmable initial modulation
amount. The MODULATION WHEEL
(2.3) adds to the amount set by this con-
trol.

2.0 LEFT-HAND CONTROLLERS.
2.1 OCTAVE SWITCHES.
These are not programmable. They raise or lower the pitch of
all oscillators by one octave.
2.2 PITCH WHEEL.
Lets you bend the pitch of what's played on the keyboard by
an amount determined by the PITCH BEND AMOUNT con-
trol (1.11).
2.3 MODULATION WHEEL.
For injecting modulation from the LFO (5.0). Adds to the ini-
tial amount of modulation programmed by the MODULA-
TION AMOUNT control (1.12).
3.0 SYSTEM CONTROLLER.
3.1 PROGRAM DISPLAY.
The large numeric LED (Light Emitting Diode) display shows
which program number has been called up. Program numbers
range from 0 to 99.
3.2 ALPHANUMERIC DISPLAY.
Through this display, the Memorymoog's computer conveys
various sorts of information about what is going on in the in-
strument. When the AUTO TUNE cycle is complete, it will
display how many voice cards have been tuned up by showing
"1, 2, 3, 4, 5 or 6 TUNED." Note that any number less than 6
indicates that the computer couldn't tune one of the voice
cards for some reason.
If you change any part of the current program in the display
by activating a control pot or switch, it will read "EDIT." If
you've changed a rotary pot's position, the left side of the dis-
play will show the value of that pot as it is in memory, while
the right side displays the current value. With this readout,
you can match old programs or return a pot to its original val-
ue.
Keyboard mode is indicated on the Alphanumeric Display
when you hit the KB MODE switch (1.7). When the RE-
CORD INTERLOCK button (3.4) is hit, the display will read
"LOCK." When a program has been recorded into memory
the display will read "RECORDED."

3.6 PREFIX BUTTONS.
PREFIX A advances programs stored in the PROGRAM SEQUENCE MODE (see below). Also
advances program number by one in normal operating mode.
PREFIX B steps in reverse through the programs in the PROGRAM SEQUENCE MODE (see be-
low). Backsteps program number by one in normal operating mode.
PREFIX C1 (hit C, hit 1, hit ENTER) saves programs onto cassette tape (for more information on
this procedure see the next section of the manual).
PREFIX C2 (hit C, hit 2, hit ENTER) loads programs from cassette tape into the Memorymoog's
memory.
PREFIX C3 (hit C, hit 3, hit ENTER) verifies correct loading of programs when putting programs
from the Memorymoog onto cassette tape.
PREFIX C4 is used for defeating voices that aren't tuning up for whatever reason. See text in next
section of the manual for details.
3.3 NUMERIC KEYBOARD.
This calculator-type keyboard is used for calling up programs and other control functions. You do
this by hitting one or two numbers (from 0 to 99) and then pressing the ENTER button.
3.4 RECORD INTERLOCK.
This switch is used to temporarily lock the front panel settings in memory. By hitting LOCK, the
Alphanumeric Display (3.2) will read "LOCK," indicating that the current panel settings are tempo-
rarily locked, and turning pots or hitting switches will have no effect. This allows you to call up an-
other patch from memory (by hitting a number and pressing ENTER) without losing the locked
patch. Hitting the LOCK switch after you've called up another patch will bring up the locked patch.
This is useful for checking edited patches against the original version.
3.5 STORING A PATCH IN MEMORY.
This is done by holding the LOCK button (3.4)
down and hitting the ENTER button (see 3.3). This
loads whatever is currently shown on the front panel
into the memory position called up in the Program
Display (3.1). Note that recording a patch is impos-
sible if the Memorymoog is "write disabled," mean-
ing that a protect function against storing unwanted
information in memory is on. To turn the protect
function off and on, you must know the four-digit
security code (see Section III). Attempting to store a
patch in memory when the disable feature is on will
cause the Alphanumeric Display (3.2) to read
"DISABLED." When a patch has been successfully
written into a memory position the Alphanumeric
Display will read "RECORDED."

PREFIX C9 makes the front panel live. The Alpha-
numeric Display (3.2) will read "LIVE PNL" when
you hit C, hit 9, hit ENTER. In this state, the front
panel controls override the memory settings.
PREFIX C0 flashes all the LEDs. This is another
service function to check if all the LEDs work. Hit-
ting any switch turns the function off.
PREFIXES D0 to D9 call up PROGRAM SE-
QUENCES. These are chains of up to 20 programs,
each arranged in some predetermined order. To call
one up hit D, hit a number from 0 to 9, and hit EN-
TER. To load a PROGRAM SEQUENCE, hit D, hit
D again, hit a number from 0 to 9 and hit ENTER to
get into PROGRAM SEQUENCE LOADING
MODE. Then to enter programs, hit the program
number, hit ENTER, hit A (ADVANCE switch) or
B (BACKSTEP switch). Repeat until you've loaded
all the programs you require. The loading mode will
stop after 10 programs are loaded. You can also use
the ADVANCE and BACKSTEP footswitches (15.3
and 15.4) to step forward and backward in the PRO-
GRAM SEQUENCE.
PREFIX C5 tunes all oscillators to unison, regardless of front panel settings.
PREFIXES C6 and C7 are electronic tuning aids for service technicians.
PREFIX C8 displays current memory status, ENABLED or DISABLED in the Alphanumeric Dis-
play (3.2). The unit powers up with the memory disabled so that you can't accidentally record a
patch and you can't use the cassette interface functions of PREFIXES C1, 2, and 3. To enable the
memory store function, hit C8 followed by the four-digit security code (see Section III). Hitting the
letter C after entering C8 tells the instrument that you want to change the security code. Do this by
entering the old four-digit code (the code of instruments fresh from the factory is 0000); the display
will read "NEW CODE" or "BAD CODE" depending on if you have it right or not. If the old code
is correct, you may then enter any new four-digit code.

4.0 FOOTPEDALS.
4.1 AMOUNT 1, PITCH, VOLUME, FILTER.
The AMOUNT knob controls the overall range of footpedal num-
ber 1 which can be routed to control the pitch of all the oscillators,
the volume, and the filter's cutoff frequency. Functions are pro-
grammable.
4.2 AMOUNT 2, MOD AMT, OSC 2.
Determines the range of a second voltage pedal which can be
routed to control the amount of modulation and/or the frequency of
the second oscillator.
NOTE: Footpedals are not supplied with the instrument. The in-
puts on the back panel (13.0) will use any voltage input that ranges
from 0 to 5 volts. If you plug in just one pedal, the input will cross-
couple so that one footpedal will control whatever is called up on
either PEDAL 1 or PEDAL 2's programs.
5.0 LFO MODULATION.
The amount of modulation is controlled by the MODULATION
AMOUNT knob (1.12) and the MODULATION WHEEL (2.3).
5.1 RATE (HZ).
Controls the LFO frequency. Variable from
.1 Hz to 100Hz.
5.2 WAVESHAPE SELECTION.
Five switches to the right of the RATE (5.1)
knob for selecting triangle, positive-going
saw-tooth, negative-going sawtooth, square,
or sample-and-hold waveshapes for the low
frequency oscillator. Selecting one wave-
shape excludes the others; waveshapes can't
be intermixed.
5.3 DESTINATION SWITCHES.
The output of the LFO can be routed to seven
places. It can be used to modulate the fre-
quencies of oscillator 1 (OSC 1), oscillator 2
(OSC 2), oscillator 3 (OSC 3), the pulse
width of oscillator 1 (PW 1), the pulse width
of oscillator 2 (PW 2), the pulse width of os-
cillator 3 (PW 3), and/or the filter's cutoff fre-
quency.

5.4 VOICE MODULATION.
The source of this modulation is selectable from either the filter's contour generator or the third os-
cillator. These affect each voice independently. Voice Modulation is independent of the LFO Modu-
lation (5.0).
5.5 OSC 3.
Controls the amount of modulation from oscil-
lator 3.
5.6 FILTER CONTOUR.
Controls the amount of modulation from the
filter's contour generator.
5.7 CONTOURED OSC 3 AMOUNT.
When switched on allows the filter's contour
generator to shape the amount of modulation
coming from oscillator three. This is useful for
creating modulation effects that vary with
time.
5.8 INVERT.
Inverts the filter contour as it's applied to the
CONTOURED OSC 3 AMOUNT (5.7) and
inverts the output of OSC 3 (6.0).
5.9 DESTINATION SWITCHES.
Voice Modulation can be routed to five places
using this set of switches: the frequency of os-
cillator 1 (OSC 1 FREQ), the frequency of os-
cillator 2 (OSC 2 FREQ), the pulse width of
oscillator 1 (PW 1), the pulse width of oscilla-
tor 2 (PW 2), and/or the filter's cutoff fre-
quency (FILTER).

6.5 FREQUENCY (oscillator 2).
A dual concentric pot which lets you tune the
second oscillator ± a minor sixth. The outer
ring is for coarse control and the inner ring is
for making finer adjustments.
6.6 FREQUENCY (oscillator 3).
Tunes the third oscillator ± a minor sixth.
However, when the KEYBOARD CONTROL
switch (6.8) is off or the LOW switch (6.7) is
on, the range of this knob is increased to 2 ½
octaves.
6.7 LOW (oscillator 3 only).
Drops the frequency of oscillator 3 by approxi-
mately 5 octaves, converting it to a low fre-
quency oscillator. With this switch on, the
range of the FREQUENCY control (6.6) is in-
creased to 2 ½ octaves.
6.8 KEYBOARD CONTROL (osc 3 only).
For turning on and off the keyboard control
voltage routed to oscillator 3. With the key-
board control voltage off, the range of the
FREQUENCY control (6.6) is increased to
2 ½ octaves.
6.0 OSCILLATORS.
6.1 OCTAVE (oscillators 1, 2, 3).
16', 8', 4', and 2' octave settings for each os-
cillator are available via these switches.
Note that the octave switches in the LEFT-
HAND CONTROLLER section (2.0) will
raise or lower the pitch of the oscillators
one octave.
6.2 SYNC 2 TO 1 (oscillator 1 only).
Locks the fundamental frequency of oscil-
lator 2 to that of oscillator 1. It is hard
sync.
6.3 PULSE WIDTH (oscillators 1, 2, 3).
Varies the width of the rectangular wave-
shape from 0 to 100%. At the outer ex-
tremes of this range the pulse width will be
so narrow that you won't hear any signal.
6.4 WAVESHAPES (oscillators 1, 2, 3).
These three switches let you call up pulse,
sawtooth, and/or triangle waveshapes.
Waveshapes can be combined.

7.0 MIXER.
Four level controls for adjusting the relative volumes of the three os-
cillators and a pink noise source as they feed into the filter. Note that
beyond a setting of 4 or 5, these controls cause the signals to clip (dis-
tort). This gives a little more punch to a sound where desired. It also
turns the triangle waves into sine waves. At a setting of 10 you will
hear some intermodulation distortion.
8.0 VOLTAGE CONTROLLED FILTER.
The Voltage Controlled Filter is the patented Moog 24db/octave low-
pass filter.
8.1 KB TRACK.
Varies the amount of voltage from the keyboard that controls the filter
cutoff frequency. You can select either } of the keyboard voltage, { of
the keyboard voltage, all of the keyboard voltage (both switches on),
or no keyboard voltage (both switches off).
8.2 CUTOFF.
Controls the cutoff frequency of the filter.
8.3 EMPHASIS.
Controls the degree of filter resonance. Oscillation begins at a little
past a setting of 7.
8.4 CONTOUR AMOUNT.
Controls the amount of voltage from the
FILTER CONTOUR GENERATOR (8.5)
that is applied to the cutoff frequency.
8.5 FILTER CONTOUR GENERATOR.
8.6 ATTACK.
Varies the attack time from 1 millisecond to
10 seconds.
8.7 DECAY.
Variable from 2 milliseconds to 20 seconds.
8.8 SUSTAIN.
Varies the sustain level of the filter contour.
8.9 RELEASE.
Adjustable from 2 milliseconds to 20 sec-
onds. The RELEASE SWITCH (10.4) and/
or the RELEASE FOOTSWITCH (15.1)
turn the release portion of the contour on
and off.

10.0 CONTOUR CONTROLS.
This set of four switches affects both Contour
Generators.
10.1 RETURN TO ZERO.
Normally, the Contour Generators, if retrig-
gered during the attack segment, start from the
existing voltage level. With this switch on, the
attack segment will always reset to zero volts.
10.2 UNCONDITIONAL CONTOUR.
With this switch off, the Contour Generators
will go into their release states (if the RE-
LEASE SWITCH [10.4] is on or the RELEASE
FOOT SWITCH [15.1] is depressed) only when
you let up on a key. With the switch on, when
you let up on a note, the Contour Generators
will go through their entire attack phase and
then jump immediately into the release state.
10.3 KEYBOARD FOLLOW.
When this switch is on, the voltage from the key
board varies the attack, decay and release times
of the Contour Generators. The lower you play,
the longer the times; the higher you play, the
shorter the times.
10.4 RELEASE.
Turns the release segment of the Contour Gen-
erators on and off. This control interacts with
the RELEASE FOOTSWITCH (15.1).

15.1 RELEASE.
Accepts a switch input for turning the release
portion of the Contour Generators on and off
(see 10.4). With the RELEASE switch on the
front panel on, depressing the RELEASE
FOOTSWITCH will turn the RELEASE
switch on the panel off. At that point, the RE-
LEASE FOOTSWITCH will act as a SUS-
TAIN PEDAL would on a piano: pressed
down, the RELEASE function of the CON-
TOUR GENERATORS (8.5 and 9.0) will be
on; let up, the RELEASE function of the
CONTOUR GENERATORS will be off.
15.2 HOLD.

THE SYSTEM CONTROLLER
The SYSTEM CONTROLLER is the heart of the
Memorymoog. Of all the front panel controls, you'll find
yourself using the SYSTEM CONTROLLER most fre-
quently. It is used to store and recall patches, set up key-
board modes, set up arpeggiation modes, control program
sequencing, access the cassette interface, and many other
present and future functions.
When you first power up the Memorymoog, you'll no-
tice that the number 1 appears in the large LED display la-
beled PROGRAM. This tells you that program #1 is called
up and ready to play. This window, the PROGRAM DIS-
PLAY (3.1), will always show which program is currently
called up and ready to play, or which program is about to
be entered.
As discussed in the quick setup guide, let your instru-
ment warm up for about 10 minutes, press the AUTO
TUNE switch (1.1), and let the instrument tune itself be-
fore playing. After the AUTO TUNE routine is complete,
program #1 will appear again in the PROGRAM DIS-
PLAY and the appropriate LEDs for program #1 will light
up. (Should you need to tune the instrument at any time
after it's been warmed up, the computer will always re-
member the state of the panel controls just prior to the tun-
ing routine and return to it.) The Alphanumeric Display
(3.2) will read "6 TUNED" indicating that all six voice
cards have been tuned successfully. If any number less
than six appears you should hit AUTO TUNE again. If all
six voice cards still fail to tune, try turning the instrument
off for a moment. Then turn it on again and hit the AUTO
TUNE switch. If all this fails, contact an authorized serv-
ice center or call our factory service center for assistance.
CALLING UP PROGRAMS
To call up a program, hit any desired number from 0
to 99 on the Numeric Keyboard (3.3) and follow it by
pressing the ENTER switch.
The ENTER switch must be pressed in order for a new
program to replace the one that is currently called up.
The new number appears on the display immediately,
but the new program is not active until the ENTER
switch is pressed.
