Summary of Contents for Moog Minimoog

  • Page 2: Table Of Contents

    The purpose of this manual is to acquaint you with the component circuitry of the Mini Moog and the operation of each of the controls and switches regulating the generators, modifiers, and control devices involved in the synthesizing of a musical sound.

  • Page 3: Basic Mini Moog Features

    The Mini Moog contains the basic components and features to be found on larger, studio- oriented synthesizers. Its five sound sources include three oscillators for the production of pitched tones, one noise source for the production of unpitched sounds, and one microphone preamplifier for the introduction of live signals.

  • Page 4: Setting Up The Instrument

    3. Plug the power cord into any conventional 117 Volt A.C. outlet. 4. Two 6’ patch-cords are supplied with the Mini Moog. If you are using a portable, guitar- type amplifier, run the cord with the phone plug at each end from the LOW level MAIN OUTPUT jack on the rear connector strip of the Mini Moog to an input on your amplifier.

  • Page 5: Output Section

    output section The Output section of the front panel includes two basic switches: the POWER switch, which turns the instrument on and off, and the MAIN OUTPUT switch, which sends the final audio signal out the MAIN OUTPUT jacks at the rear and into your amplifier. In addition, there are volume controls for the MAIN OUTPUT and HEADPHONE signals, and an A-440 switch, all of which will be described below.

  • Page 6: Oscillator Bank

    oscillator bank This group of circuits contains three separate and independent oscillators. Each oscillator produces a waveform which repeats regularly, thereby giving rise to a tone of definite pitch. The audio signal outputs of the three oscillators are activated by turning on mixer switches (C), (E), and (G).

  • Page 7: Modulation Mix

    controllers This section will demonstrate the use of the controls located to the left of the Oscillator Bank (used in tuning and setting up a sound), as well as the keyboard and the manual controls on the panel to its left (used during performance). All of these controls have an effect on the os- cillators’...
  • Page 8 11. The TUNE control (1) is used to tune up the Mini Moog oscillators to the pitch of the en- semble in which it is being used, or to its A-440 reference tone. Check to see that switch (C) is on, and notice that, when a key is depressed, the pitch moves up and down by a few tones as the TUNE control is turned through its range.
  • Page 9 Mini Moog. 1. The OSCILLATOR VOLUME controls (12, 13, and 14) are used to regulate the relative levels of the audio signals produced by the three oscillators.

  • Page 10: Filter And Filter Contour

    The Mini Moog features a wide-range lowpass filter. This filter attenuates, or cuts out, those frequency components of an audio signal which lie above a variable cutoff frequency, while passing those components which lie below it.
  • Page 11 TIME control from left to right. You will hear the brightness of the note increase sharply at first, and then more gradually as the attack time increases. 4. The DECAY TIME control (21) determines the duration of the second segment of the contour, the fall from the initial peak to the sustain level.
  • Page 12 It thus is available as a sixth sound source within the Mini Moog. The pitch of this additional oscillator may be controlled by the five other controls on the keyboard. The sixth sound source may be used alone or mixed with the other sound sources to achieve a variety of complex effects.

  • Page 13: Loudness Contour

    The volume of the audio signal which passes through the Modifiers section of the Mini Moog is contoured by the Loudness Contour controls. These controls are connected to a contour generator which supplies a control signal to the amplifier. Like the filter contour signal, the loudness contour signal is composed of three segments −...

  • Page 15 The 962 allows one to extend a sequence of one function to up to 24 events (example: 24 note repeating bass line). The 961 extends flexibility in triggering the contour generators and can be used to synchronize the MINI MOOG with external equipment (example: tape recorded click track).

  • Page 17: Left-Hand Controller

    The rocker switches in the left hand controller section have replaced the momentary push but- tons used previously. Jacks have been added so that the performer can connect foot switches to engage GLIDE and DECAY functions. R. A. Moog will soon make these momentary switches available as an accessory.
  • Page 18 Mini Moog Model D Back Panel Adjustments (on instruments with serial number 1237 and higher) As with any fine musical instrument, the Mini Moog may require periodic tuning and adjustment. Holes in the back panel provide access to internal trim potentiometers for necessary adjustments. DO NOT ATTEMPT TO REMOVE THE BACK PANEL.

Depress lowest A key and zero beat OSCILLATOR 1 with OSCILLATOR 2 using OSCILLA- TOR 2 low end adjustment (D).
