For the first time since 1981, Moog Music has officially resumed production of the Minimoog Model D. The Minimoog Model D was the world’s first portable synthesizer and served as the archetype for all electronic keyboards that followed. First released in the early 1970’s, the instrument gained worldwide acclaim for combining the colossal sound of Moog’s large-format modular synthesizers with the accessibility of pre-wired modules. Over the last 40 years, some of the world’s most influential artists like Trent Reznor, Gary Numan, Dr. Dre, Keith Emerson and Herbie Hancock have shaped their unique sounds and forged new musical genres using the Minimoog Model D. This valuable sonic tool is now made available to veteran synthesists and the next generation of electronic pioneers. Each newly built Minimoog Model D is lovingly handcrafted by the employee-owners at the Moog Factory in Asheville, NC. This 3-oscillator, monophonic, analog synthesizer is securely housed in a locally-sourced Appalachian hard-wood enclosure and hand-finished aluminum chassis. The circuit boards retain the exact component placement and through-hole design of a beloved 1970’s era Minimoog Model D. Though no changes have been made to the original sound engine or audio signal path, the Minimoog Model D now includes a series of popular functional modifications that expand this legendary instrument’s sonic capabilities. These modifications include a premium Fatar keybed with velocity and after pressure available via top panel CV jacks, a dedicated analog LFO with triangle and square waveshapes, CV outputs for pitch, gate, velocity and after pressure, basic MIDI integration, and a mixer overload modification, which when engaged, allows the Minimoog Model D to conjure thicker and far more overdriven sounds than before. NOTE: Due to the complexity of the build process coupled with the demand for other Moog instruments, we are only able to produce a small number of Minimoog Model D units per month. • 3 vintage Moog oscillators• Classic Moog low pass ladder filter with resonance• Analog circuit boards recreated using original designs and component placement• Custom reissued transistors critical to sound quality and character• Military spec precision resistors• Precision Linear System matched JFETs in oscillators• Classic thermoset, gnarled pitch and mod wheels• CV Modifications: outputs added for Pitch, Aftertouch, Velocity and Gate (Aftertouch and Velocity have dedicated output level attenuators) • Modulation Modifications: analog Triangle/Square wave LFO and Filter Envelope added as modulation sources, as well as an External Modulation CV input• Overload Modification: the output of the Minimoog Model D is automatically scaled and fed back to the External Audio Input for instantly available overdrive• Improved circuit board connectors for touring reliability• Fatar TP-9 keybed with velocity and aftertouch• MIDI in, out and thru SOUND SOURCES (5)Oscillators x 3Noise GeneratorExternal InputOSCILLATORSFrequency Range: 0.1 to 20 kHz (In Six Overlapping Ranges)Oscillator Stability (short term) > 0.25 %Waveforms: TriangleTriangle-Sawtooth (Oscillator–1, Oscillator–2) Reverse Sawtooth (Oscillator–3)SawtoothRectangleWide PulseNarrow PulseNOISE GENERATORWhite PinkLFORate: 0.05Hz to 200 HzWaveform: Triangle (knob down); Square (knob up)External InputInput Range: +10 millivolts to +2 voltsInput Impedance: 1MEG OhmsFilterFilter Type: Voltage Controlled Low Pass (Moog Ladder Filter)Cutoff Frequency Range: 10 Hz to 20 kHzFilter Slope: 24 dB per OctaveFilter Resonance: At Cutoff FrequencyContour GeneratorsAttack Time: 1 millisecond to 10 secondsDecay Time: 4 milliseconds to >35 secondsSustain Level: 0 to 100% of Contour peakFilter Contour Width: 0 to 4 OctavesVoltage Controlled Amplifiers (VCA)Loudness Contour Dynamic Range: 80 dBAudio Input Levels1/4” External Signal Input Voltage : +10 millivolts (min); +10 volt (max.)
