  • Page 6: 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. The SP’s front panel has four variable-function edit controls for real time adjustment of the Modulation, Oscillator, Filter and Envelope Generator parameters, plus dedicated controls for Fine Tuning, Octave Switching, Glide, and Volume.
  • Page 7 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.

  • Page 8: Signal Flow

    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.

  • Page 9: Basic Operation

    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. •...

  • Page 10: The Components

    THE COMPONENTS Slim Phatty User’s Manual - The Components The Components Now let’s take a look at the individual module components that make up the Slim Phatty Synthesizer, start- ing with the Oscillator section and moving right across the front panel, explaining the features and functions of the Filter, Envelope Generator and Output sections.
  • Page 11 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.

  • Page 12: Filter Section

    An 18dB/Octave slope is steeper still, with a corresponding frequency rejection. Finally, a 24dB/Octave slope provides the steepest rejection of frequen- cies above the cutoff point. The classic Moog ‘ladder’ filter is a 24dB/Octave lowpass filter. The Moog filter also features a parameter called Resonance. This parameter adds a resonant peak at the cutoff frequency.
  • Page 13 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.

  • Page 14: Envelope Generators Section

    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 counter- clockwise.
  • Page 15 The KB GATE jack on the side panel is a trigger input that accepts a footswitch (momentary, normally closed like the Moog FS-1) or a gate signal. Pressing the footswitch or applying a gate signal (+5V) causes both envelopes (Volume and Filter) to trigger.

  • Page 16: Modulation Section

    Slim Phatty User’s Manual - The Components D. The Modulation Section Modulation is the heart of making interesting sounds with analog subtractive syn- thesis. 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.

  • Page 17: Output Section

    The jack accepts a positive control voltage from 0 to 5 Volts, or an expression pedal like the Moog EP-2. A voltage of 0 volts silences the SP, and a voltage of 5 volts corresponds to the output level set by the VOLUME control knob.

  • Page 18: Input/Output Panel

    Moogerfooger EP-2 (ring = +5.5 supply to the pedal, tip = variable CV return), or a control voltage from –5 to +5 Volts. The KB Gate Input accepts a footswitch (a momentary, normally-closed footswitch like the Moog FS-1) or a +5 Volt Gate Signal. MIDI Connectors (DIN and USB): These are DIN connections for MIDI In/Out/Thru, and MIDI USB connector.

  • Page 19: Interface Panel

    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.

  • Page 60: E - Tutorial

    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 hap- pen to occur in our range of hearing.
  • Page 61 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.
  • Page 62 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 high- pitched leads (like a flute) or adding a beefy sub-bass to bass sounds.
  • Page 63 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.
  • Page 64 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. For example, the Moog Voyager has three oscilla- tors, two filters, two amplifiers, an LFO, two extensive modulation sections, and the Voyager’s third oscillator can act as an additional LFO.
