FOREWORD Foreword We here at Moog Music are grateful that you have chosen the Slim Phatty® analog synthesizer for your musical pursuits, and hope you find it to be an inspiring instrument for years to come. Good things can come in small packages – and “the Slim” is no exception. Making the Slim Phatty has been a labor of love, transforming the electronic workings of the Little Phatty® into a package that is easily used as a desktop or a 3U rack-mount unit.
THE BASICS Slim Phatty User’s Manual - The Basics How to Use this Manual The Setup and Connections section explains how to unpack, setup and connect the Slim Phatty, and provides a quick start to get you up and running with your new synthesizer. The Components section offers detailed explanations of the components that create and modify sound. First time users should check out the Tutorial in Appendix E, where you will find an explanation of sound and subtractive synthesis.
Slim Phatty User’s Manual - The Basics Set up Make sure you have an adequate place to set up. Use care when unpacking the Slim Phatty, and be sure to save the carton and all packing material in case you need to ship the Slim Phatty for any reason. Connect to Power & MIDI Connect the Slim Phatty’s power receptacle to a properly-wired wall outlet using the supplied AC power cord. The Slim Phatty’s universal power supply will operate with a power source from 90 to 250 Volts AC, 50/60Hz.
Slim Phatty User’s Manual - The Basics Overview and Features The Slim Phatty (SP for short) is a monophonic analog synthesizer that is a descendant of the classic Minimoog Model D. The SP features 2 ultra-stable oscillators, a genuine Moog 24dB/Octave low pass filter, two 4-stage analog envelope generators and a flexible modulation matrix.
Slim Phatty User’s Manual - The Basics Front Panel (con’t): 5. The Envelope Generator (EG) section - contains two ADSR-style envelopes, one for the Filter and one for the Volume. The EG section includes controls for adjusting the Attack, Decay, Sustain and Release parameters of each envelope. 6. The Output section - includes controls for adjusting the Master Volume, and a switch to toggle the Audio output on and off.
Slim Phatty User’s Manual - The Basics Signal Flow To understand the operation of the Slim Phatty, refer to the diagram below. The diagram shows the flow of the audio, control voltage and modulation signals in the Slim Phatty. Heavy lines are used to indicate audio signals, which flow from left to right. Lighter lines indicate the control voltages (CV’s), which flow from the top and bottom. Dotted lines indicate programmable modulation routings.
Slim Phatty User’s Manual - The Basics Basic Operation The SP has two operating modes: Master and Preset. • Master mode allows you to access and change global parameters and other utility options. A complete list of the Master mode functions and parameters is shown on page 26. • Preset mode allows you to access the presets and manipulate the sound from the front panel controls. The Preset mode is the main operating mode for editing and playing the SP. Information on Preset mode is found on page 23.
Slim Phatty User’s Manual - The Components THE COMPONENTS The Components Now let’s take a look at the individual module components that make up the Slim Phatty Synthesizer, starting with the Oscillator section and moving right across the front panel, explaining the features and functions of the Filter, Envelope Generator and Output sections. Then we’ll cover the Modulation section, the Input/ Output Back Panel, and the User Interface section. A.
Slim Phatty User’s Manual - The Components Waveform: Each oscillator has a switch labeled WAVE that allows the analog edit control to modify the waveform. The waveform is continuously variable from triangle, to sawtooth, to square, to rectangular. The waveform is morphed gradually from one to another as the value control is rotated. The legend around the analog edit control for the oscillator section indicates the knob positions to obtain the triangle, sawtooth, square and skinniest pulse waveforms.
Slim Phatty User’s Manual - The Components B. The Filter Section Filters are used for adjusting the timbre of an audio signal. Filters modify sound by attenuating some frequencies while allowing others to pass through unaffected. An important term to understand regarding filters is “Cutoff Frequency”. This is the point at which frequencies begin to be rejected. The SP features a lowpass filter, which behaves as its name indicates: it allows low frequencies to pass and rejects high frequencies.
Slim Phatty User’s Manual - The Components Finally, the Overload (O.L.) parameter allows you to set the amount of signal clipping from none to soft to hard clipping as the amount is increased. The results you get with Overload will depend on the settings of the oscillator waves and levels, and the filter cutoff and the filter resonance settings in addition to Overload amount. Note that Overload is not the same distortion you’d get from a fuzz box.
Slim Phatty User’s Manual - The Components TECH NOTES: 1. The SP’s Overload circuit uses asymmetrical clipping, which clips each side of the waveform differently. Asymmetrical clipping circuits tend to produce tones with unique richness and character. 2. The Overload circuit has no effect on the sound when the analog edit control is set fully counterclockwise.
Slim Phatty User’s Manual - The Components Envelope Generator Section Controls: Attack: When the ATTACK switch is selected, the analog edit control is used to adjust the Attack time of the corresponding envelope from 1 msec to 10 seconds. Decay: When the DECAY switch is selected, the analog edit control is used to adjust the Decay time of the corresponding envelope from 1 msec to 10 seconds.
Slim Phatty User’s Manual - The Components D. The Modulation Section Modulation is the heart of making interesting sounds with analog subtractive synthesis. The SP’s Modulation section opens up a world of modulation possibilities that were not available on the original Minimoog. The Modulation section allows you to select from six modulation sources, specific one of four destinations, and set the modulation amount.
Slim Phatty User’s Manual - The Components The Modulation Section (con’t) Destination: The DESTINATION switch selects the destination of the modulation. The modulation destination is chosen in the same manner as the source. The modulation destination selections are: - Filter (affects filter cutoff) - Pitch (affects the pitch of both oscillators) - Wave (affects the waveform of both oscillators) - Osc 2 (affects the pitch of Oscillator 2) E.
Slim Phatty User’s Manual - The Components F. Input/Output Panel The Back Panel provides all of the input and output connections. In addition to Audio Input/Output jacks, there are CV and Gate inputs, connections for MIDI, and the power connector and power switch. Power Connector: This is a standard AC power inlet, Use only a power cord designed to mate with this receptacle. The Little Phatty’s built-in universal power supply is designed to work with power inputs of 90-250 Volts AC, 50/60 Hz.
Slim Phatty User’s Manual - The Components G. Interface Panel The Interface Panel is located on a far left of the instrument. The Interface Panel provides a status display and controls for all of the Slim Phatty’s software functions and instrument settings. The status display is an LCD screen located in the center of the panel above the section controls. When the SP is first powered on, the screen will display the message: Slim Phatty Version X.
Slim Phatty User’s Manual - The Components Enter/Store: The ENTER/STORE button is used to enter changes and store edited presets in PRESET mode and to execute SysEx and System Utility functions in MASTER mode. Fine Tune: The FINE TUNE control is used to tune the Slim Phatty’s oscillators ±3 semitones for matching an external reference pitch. Glide On/Off: The GLIDE ON/OFF switch enables or disables the glissando effect between notes. Glide is ON when the switch LED is lit.
THE USER INTERFACE Slim Phatty User’s Manual - The User Interface Preset Mode Preset mode is the default mode when the SP is powered on. Preset Mode is used to access presets and provide control for editing, naming and storing sounds. Preset sounds are selected using the VALUE knob. As the VALUE knob is advanced, the next preset appears in the display and is immediately available to be auditioned (you do not need to ‘activate’ the preset to hear it).
Slim Phatty User’s Manual - The User Interface NOTE: When the Arpeggiator is running, the ENTER/STORE button is also used to activate the latch if the Latch parameter has been enabled. For more on the Arpeggiator and Latch functions, see page 40. Changing A Preset Name Changing a preset name is a simple operation. The characters in a name are individually selected by moving the cursor to the desired location and scrolling through the character list.
Slim Phatty User’s Manual - The User Interface Tap Tempo Tap Tempo is an easy and intuitive way to adjust the speed of the LFO Rate or the Arpeggiator Clock. The Tap Tempo function is always available for any preset in PRESET Mode. Tap Tempo can be used to adjust the LFO Rate when the Arpeggiator is not running, or adjust the Arpeggiator Clock when the Arpeggiator is running.
Slim Phatty User’s Manual - The User Interface Master Mode Master Mode is used to access the global settings and Advanced Preset settings for the Slim Phatty, and the routines for sending and receiving data. To enter master mode, press the MASTER button. By default, the first master menu entry is Performance Sets. When switching between the Master and Preset modes, the last used master menu entry appears. When the master menu is active, the VALUE knob is used to scroll through menu entries.
Slim Phatty User’s Manual - The User Interface ADVANCED PRESET: Advanced Presets is a set of menus that allows you to access additional parameters for the selected preset. These parameters are stored individually for each preset. There are eleven Advanced Preset menus: - Filter Poles - EGR Release - Gate Trigger Options - Filter Sensitivity - Additional LFO Modulation Sources (SRC5 & SRC6) - Pitch Bend - Secondary Modulation destinations.

To change the status of either parameter use the CURSOR button to highlight the parameter, then use the VALUE knob to set the new parameter value.
Slim Phatty User’s Manual - The User Interface NOTE: While you are in this menu with AutoTune enabled, the output of the SP will be muted (the Output ON/OFF button status will not change, however). The reason for muting the output is that AutoTune uses a special Calibration Preset tone which isn’t very musical. The SP’s output will remain muted as long as you stay in this menu, or until you disable AutoTune.
Slim Phatty User’s Manual - The User Interface PRECISION MODE: Precision Mode is a feature that allows precision editing of SP parameters using the VALUE knob. Each SP parameter stored has a value from zero to 4095. In Precision Mode that value is displayed on the second line on the screen. To edit a parameter in Precision Mode, press the corresponding parameter button on the front panel (for example, Filter Cutoff). You will see that parameter name along with its value on the display.
Slim Phatty User’s Manual - The User Interface MIDI CHANNELS IN AND OUT: This menu is used to select the SP’s MIDI In and Out channels. The SP can only send and receive on one channel at a time, but each channel can be set independently. To change the MIDI channel, use the CURSOR button to highlight the desired parameter, then use the VALUE knob to select the new parameter value.
Slim Phatty User’s Manual - The User Interface MIDI SETUP (con’t) The fourth page of the MIDI Setup menu allows you to select the MIDI output connection. To specify the MIDI output connection, use the CURSOR button to highlight the output selection, then use the VALUE knob to select the new output. Values: NONE, DIN, USB, DIN/USB; the default is DIN/USB The fifth page of the MIDI Setup menu allows you to select the routing of the MIDI Merge function for the USB input.
Slim Phatty User’s Manual - The User Interface MIDI SETUP (con’t) The seventh page of the MIDI Setup menu allows you to set up multiple Moog synths as a polyphonic synth stack. The settings are ‘POLY: OFF’ or ‘POLY: (#) of (##)’. The first number represents which note this particular SP is assigned to play, the second number sets the total number of available voices.
Slim Phatty User’s Manual - The User Interface SYSEX MENU: SysEx (System Exclusive) is a set of commands to transmit and receive selected presets, bulk dumps and firmware dumps. For more information on SysEx commands, see the SysEx Menus section on page 42. SYSTEM UTILITIES: System Utilities is a set of commands used to perform a system reboot, restore factory default values or perform various system calibrations on the instrument. For more information, see the System Utilities Menus section on page 45.
Slim Phatty User’s Manual - The User Interface B. Advanced Preset menus The Advanced Preset menu provides a set of additional programming parameters for each preset. These parameters are stored individually for each preset. FILTER POLES: This menu allows you choose the number of Filter Poles for the preset. The number of Filter Poles specifies the filter response, from a gentle 6db/octave (1 pole) to a steep 24db/octave (4 poles).
Slim Phatty User’s Manual - The User Interface MOD SOURCE 5 (MOD SRC 5): This menu allows you to select one of two modulation options that will be used when the FILT ENV source is selected on the front panel (Modulation Source 5). FILT (Filter Envelope) is the default source, but S-H (Sample & Hold) can be chosen as an alternate. To change the parameter, use the CURSOR button to highlight the parameter, then use the VALUE knob to set the new parameter value.
Slim Phatty User’s Manual - The User Interface KEYBOARD PRIORITY (KB PRIOR): The Keyboard Priority menu allows you to select the keyboard priority for individual presets. The default is GLOB (Global), which inherits the global keyboard priority setting from the Master KEYBD PRIORITY menu, but this can be changed to low note, high note or last note priority. To make a change, use the CURSOR to move to the priority parameter field, then use the VALUE knob to select the desired value.
Slim Phatty User’s Manual - The User Interface POT MAPPING (con’t): Press the CURSOR button once more to select whether the assignment applies to internal only (INT), external only (EXT) or BOTH. Pressing the CURSOR button again will return you back to the beginning. Once programmed, Pot Mapping is enabled in a section by selecting the active parameter in that section. For example, suppose Pot Mapping is configured for the MODULATION knob to send MIDI CC#10.
Slim Phatty User’s Manual - The User Interface ARPEGGIATOR: The Arpeggiator provides a wide range of musical sequencing possibilities. The Arpeggiator is programmed for each preset individually through the seven menu pages described here. The Arpeggiator is activated from the front panel (see Activating the Arpeggiator and Latch, page 52). To enter the Arpeggiator Menu, use the CURSOR to highlight ‘ARPEGGIATOR’ and press ENTER.
Slim Phatty User’s Manual - The User Interface ARPEGGIATOR (Con’t): The third page of the Arpeggiator menu allows you to specify the Arpeggiator Clock Divider. The available Arpeggiator Clock Divider values are the same as the LFO Clock Divider (see table on page 28). To make a selection, use the CURSOR button to move to the divider parameter field, then use the VALUE knob to select the desired divisor value. The default clock divisor value is ‘1/4’.
Slim Phatty User’s Manual - The User Interface ARPEGGIATOR (Con’t): The seventh page of the Arpeggiator menu allows you to enable or disable the Latch function. The Latch allows the Arpeggiator to keep repeating the arpeggio state when you remove your hands from the keyboard. The Latch menu arms the Latch function the same way the Arpeggiator ON/OFF menu arms the Arpeggiator.
Slim Phatty User’s Manual - The User Interface C. SYSEX Menus (Con’t) SEND ALL PRESETS: This option allows you to send the system exclusive data for archiving the complete bank of presets in the SP’s memory. To complete this command, enable the device that is to receive the SysEx data. Once the remote SysEx device is enabled, press ENTER to start the data transfer.
Slim Phatty User’s Manual - The User Interface Receiving SysEx Data The SP is able to receive System Exclusive data at any time without any special prior setup. SysEx files are recognized and received automatically when a SysEx data transfer is initiated. The Little Phatty’s LCD screen will display the status of SysEx data transfers as follows: SINGLE PRESETS: The SP will briefly display a ‘RECEIVING SINGLE PRESET’ message whenever a single preset is transmitted via SysEx.
Slim Phatty User’s Manual - The User Interface D. System Utilities Menus System Utilities provide a set of useful system commands, including commands to calibrate, restore factory defaults and set global system options. There are six pages of System Utilities menus, beginning with the Version number display. The second page of the System Utilities menu displays the Headphone Volume (HP VOL) menu , which allows you to scale the headphone volume in relation to the output volume.
Slim Phatty User’s Manual - The User Interface While the restore process is taking place, the LCD will briefly display a ‘RESTORING FACTORY DEFAULTS’ message. When complete, the screen will return to the System Utilities menu. The sixth page of the System Utilities menu allows you to calibrate the Slim Phatty. In the past, calibration of analog synthesizers had to be performed manually by experienced service personnel.
Slim Phatty User’s Manual - The User Interface CALIBRATION (con’t) NOTE CALIBRATION: This calibration option allows you to select Note calibration. This calibrates individual notes exactly for each oscillator and octave setting. Press ENTER to access the Note calibration menu. The Note calibration menu will be displayed, allowing you to set the calibration range. The default note range is MIDI notes 12 - 116.
Slim Phatty User’s Manual - The User Interface CALIBRATION (con’t) PITCH WHEEL AMOUNT: This option allows you to select Pitch Wheel Amount calibration. This calibrates the Pitch Wheel Amount parameter to precise semitone values (± 2, 3, 4, 5, 7 and 12). Press ENTER to access the Pitch Wheel Amount calibration menu. You will be asked if you wish to proceed. Use the VALUE knob to select YES or NO, then press ENTER.
Slim Phatty User’s Manual - The User Interface CALIBRATION (con’t) OSCILLATOR 2 FREQUENCY (OSC2 FREQ): This option allows you to select OSC2 Frequency Calibration. This calibrates the OSC2 FREQ control so that turning the editing dial all the way CCW turns OSC2 down exactly a fifth (-7 semitones) and turning all the way CW turns OSC2 up exactly a fifth (+7 semitones). Press ENTER to access the OSC2 Frequency Calibration menu. You will be asked if you wish to proceed. Use the VALUE knob to select YES or NO.
Slim Phatty User’s Manual - The User Interface Performance Sets Performance Sets is a feature that allows you to customize the order of SP presets for a live performance situation or to enhance your productivity in a studio environment. Performance Sets are based on the idea that during a performance, you may need to switch between a sequence of sounds that doesn’t necessarily match up to the preset locations.
Slim Phatty User’s Manual - The User Interface Editing Performance Sets To edit a Performance Set, use the CURSOR key to select the Performance SET number (1-4), ENTRY location (1-8) and PRESET (00-99). For example, to select the SET number, press the CURSOR button once to highlight the SET number for editing. Press the CURSOR button a second time to advance to the ENTRY location, and a third time to advance to the PRESET. In the example show here, the SET number is ready to be changed.
Slim Phatty User’s Manual - The User Interface Activating the Arpeggiator and Latch Turning the Arpeggiator ON/OFF When a preset has the Arpeggiator function enabled, you turn the Arpeggiator ON and OFF by pressing the VALUE encoder switch (you must be in PRESET mode to engage the Arpeggiator). When the Arpeggiator is ON, an ‘A’ will appear on the bottom line of the display: With the Arpeggiator ON, any note or group of notes you play will be sequenced according to the settings in the Arpeggiator menu.
Slim Phatty User’s Manual - The User Interface Arpeggiator Examples The Arpeggiator takes the currently played note or group of notes and forms an arpeggio based on the Arpeggiator Menu settings. Here are some simple examples of the Arpeggiator function: Example 1. Pattern = UP, Octaves = 1, Mode = LOOP PLAY & HOLD NOTE THE ARPEGGIATOR PLAYS C3 C3, C4, C3, C4... Add E3 C3, E3, C4, E4...

Slim Phatty User’s Manual - Appendices APPENDICES Appendix A - LFO Sync Modes There are two LFO Sync Modes: INTERNAL and MIDI CLOCK. INTERNAL: When the LFO Sync Mode is set to ‘INTERNAL’, the LFO rate is controlled directly via the MODULATION knob (when the LFO RATE panel button is selected), or by Tap Tempo, or by sending a MIDI CC#3 command with a value between 0-127 (MIDI CC#3 controls the LFO RATE).
Slim Phatty User’s Manual - Appendices Appendix B - Arpeggiator Clock Source There are three Arpeggiator Clock Sources: Internal (INT), LFO, and MIDI Clock (MIDI). Detailed descriptions of these clock source options appears below. INTERNAL: When the Arpeggiator Clock Source is set to INTERNAL, the Arpeggiator runs at the internal Arpeggiator Clock rate. This defaults to the clock rate saved in the currently-active preset.
Slim Phatty User’s Manual - Appendices Appendix C - The Calibration Preset The SP has a specific Calibration Preset that is stored in a non-volatile memory location labeled ‘CA’ (this preset location appears after preset 99). The Calibration Preset is a single-oscillator squarewave tone that plays Oscillator 1 at full level. This preset is used primarily for the SP’s AutoTune function, but it can also be used for tuning the SP with an external tuner.
Slim Phatty User’s Manual - Appendices Appendix D - Accessories To further enhance the functionality and appearance of the Slim Phatty, Moog Music offers the following optional accessories. For complete information on everything listed here, including pricing and ordering info, see your Moog dealer, or visit www. moogmusic.com Rack Ears For those who wish to rack mount their SP, Moog Music offers matching metal rack ears for the Slim Phatty. Ships with the required washers and screws.
Slim Phatty User’s Manual - Appendices Appendix E - Tutorial For those who are new to the world of electronic music, let’s take a few moments to go through the basics of sound and synthesis. Sound is simply the audible change in air pressure. When we perceive sound, our ears are responding to variations in air pressure that happen to occur in our range of hearing. The rate of these variations is called the Frequency, which is measured in cycles per second, or Hertz (Hz).
Slim Phatty User’s Manual - Appendices The Subtractive Synthesis Model The Oscillator is the starting point of Subtractive Synthesis, for it is here that the initial sound is created. The oscillator creates electrical vibrations which function in a manner similar to the strings of a guitar; they create the signal source that the rest of the system will use to modify and shape the sound. The key oscillator parameters are pitch and waveform.
Slim Phatty User’s Manual - Appendices Like the square wave, the triangle wave only contains odd harmonics, but the levels of the harmonics in a triangle wave are much less. The triangle wave has a soft, slightly buzzy sound that is suitable for highpitched leads (like a flute) or adding a beefy sub-bass to bass sounds. The sine wave is the purest waveform of them all. It has no harmonics, so it produces a very pure tone.
Slim Phatty User’s Manual - Appendices Returning to our Subtractive Synthesis model, the first of the auxiliary components is the keyboard. The keyboard provides a familiar musical instrument ‘interface’ that produces a control voltage and trigger signal whenever a key is pressed. The level of the control voltage signal is a function of which key is pressed - the higher up on the keyboard you play, the higher the level of the control voltage.
Slim Phatty User’s Manual - Appendices So there you have it - the six basic components that make up a synthesizer based on the subtractive synthesis model. Keep in mind that most ‘subtractive’ synthesizers often include more than one of each component. This is especially true of the oscillators and envelope generators (the Little Phatty has two of each), but may also be true of filters, amplifiers and LFO’s.

Slim Phatty User’s Manual - Appendices Appendix I - Using the CP-251 with the Slim Phatty The Moogerfooger® CP-251 Control Processor makes an ideal companion to the Slim Phatty synthesizer. The CP-251 provides an LFO with two waveforms (Triangle/Square), a Sample & Hold circuit with two outputs (stepped/smooth), a Lag Processor, a Noise source, a Mixer and two Attenuators. The CP-251 greatly expands the sonic palate of the SP, allowing for the creation of interesting new sonic textures.
Slim Phatty User’s Manual - Appendices To set the transposition interval, press the EP-2 footpedal all the way down and slowly adjust the Attenuator on the CP-251 while striking a note on the SP’s MIDI controller. The pitch will go up as you raise the Attenuator level. Rock the EP-2 pedal between full up and full down positions to hear the difference in pitch, and adjust the Attenuator until the desired interval is reached.

GLOSSARY Slim Phatty User’s Manual - Glossary Glossary Here are a few key terms that cover the basics of sound generation as used in the Little Phatty synthesizer. ADSR – Abbreviation for Attack, Decay, Sustain and Release, the four stages of an envelope control voltage. Amplitude – The strength of a sound’s vibration measured in Decibels (dB). Amplitude corresponds to the musical term Loudness. Continuous Controller (CC) – A type of MIDI message used to transmit control commands.
Slim Phatty User’s Manual - Glossary EEPROM – EEPROM stands for ‘Electrically Erasable Programmable Read Only Memory’. This is a type of digital memory used to store information, even after the power is turned off. In the Little Phatty, the EEPROM is used to store global settings and presets, and operating system parameters such as tuning information. Filter – A circuit that removes some frequencies and allows other frequencies to pass through the circuit.
Slim Phatty User’s Manual - Glossary Low Frequency Oscillator – Also called an LFO, this is a special type of oscillator that generates signals primarily below the range of human hearing (generally below 20 Hz). LFOs are typically used as a source of modulation. For instance, an LFO with a triangle waveform, set to about 6 Hz and modulating the pitch of a VCO results in vibrato. Changing the LFO waveform to a square wave will result in a trill. An LFO modulating a VCA with a triangle wave creates tremolo.
Slim Phatty User’s Manual - Glossary Sound – Audible vibrations of air pressure. For electronic sounds such as those produced by a synthesizer, loudspeakers are used translate the electrical vibrations into the changes in air pressure which we perceive as sound. Subtractive synthesis – A method of creating tones using harmonically rich (bright) source material, and then removing (or in some cases emphasizing) various frequency components to create the desired sound.
