Pittsburgh Modular Synthesizers Semi-Patchable Desktop Monophonic Analog Synthesizer

Pittsburgh Modular Synthesizers Microvolt 3900 takes a new approach to building a raw, analog monosynth with a host of unconventional and inspirational features. Patch cables are optional!

Creative synthesis design
With its new temperature-stabilized dual-VCA oscillator core, the analog audio engine of Microvolt 3900 feeds a set of timbral waveshapers crafted for deep harmonic shaping, enabling a layer of additive synthesis alongside the classic subtractive synthesis waveforms.

Waveforms are fed into the binary filter, a custom state variable filter architecture offering near infinite resonance with or without self-oscillation. Sonically, this creates a juicy, fluid filter, adding depth and energy to the oscillator that can scream if you ask it to.

  • Voltage-controlled West Coast-style wavefolder
  • Switchable, harmonically rich sine wave
  • External preamp with independent 30× gain and output level controls
  • Classic Pittsburgh Modular low pass filter with extended resonance
  • Dynamic VCA with standard VCA and dynamic low pass gate modes
  • Variable overdrive on output
  • Multi-mode sequencing arpeggiator
  • Chaotic random CV and gate generator
  • Multi-tasking function generator works as a voltage controlled envelope, LFO and oscillator
  • Highly-tuned ADSR envelope generator
  • 39-point eurorack format compatible patch bay

Open electronic experimentation
Microvolt 3900 is patched internally and does not require patch cables to dial in a wide variety of unique and powerful sounds. For deeper experimentation there's a 39-point eurorack format-friendly 1/8" jack patchbay for complete signal routing control over a full complement of audio and modulation options. A four-stage envelope generator, multi-purpose function generator, wide-range LFO, chaotic random source, arpeggiator, sequencer and MIDI-to-CV control are also available to create dynamic sounds unique to Microvolt 3900.

Voltage-controlled oscillator
Temperature-stabilized, dual VCA-based analog saw core oscillator simultaneously outputting saw, sine, pulse and folded waves. Modulation options include exponential frequency modulation, pulse width and fold timbre. The sine wave is capable of switching from a clean sine to a harmonically rich, half-rectified sine wave.

Waveform mixer
Microvolt 3900's waveform mixer lets you blend oscillator waveforms, analog noise and preamp. The preamp uses a 30× soft clipping overdrive circuit to push external audio or internally patched feedback loops from mellow to monstrous.

Binary filter
Based around the classic Pittsburgh filter circuit, the binary filter in Microvolt 3900 utilizes a smooth two-pole, state variable core to create a buttery smooth frequency sweep paired with a new resonance circuit that slides from clean, gummy bubbles to a screaming, overdriving freakout.

Dynamic VCA
Organic and percussive, the dynamic VCA utilizes an entirely new, all-analog design to replicate the impact transients and vibrance of a percussion hit. The result is a versatile VCA section that sounds natural and energetic. The dynamic VCA works in two modes: high quality VCA and a low pass gate mode that manages both timbre and loudness at the same time.

Output overdrive, line level and headphone outputs
The output section uses a proprietary 30× symmetrical overdrive circuit for additional sound sculpting; results can vary from subtle warmth to squared out, harmonic bliss. A high quality stereo headphone amplifier and a monophonic line level output are controlled by a master volume slider.

MIDI / arpeggiator
A 128-note MIDI-to-CV converter with assignable modulation output and variable pitch bend has been paired with a multi-mode arpeggiator. The arpeggiator offers 'as played,' hold, transpose, multiple octave, random and 16-step sequencing with rest and note repeat modes. Octave up and down buttons shift the frequency of the oscillator ±2 octaves.

Modulation sources
Microvolt 3900's balance control mixes a free-running, wide-range LFO with variable ramp and pulse waves with a complex random CV. The random section offers multiple modes from standard sample-and-hold type response to evolving six-stage shift register pseudo-random CV patterns.

Function generator
Multi-function, periodic control voltage generator can be used as a voltage-controllable two-stage attack/decay envelope generator, voltage-controlled LFO and voltage-controlled oscillator, perfect for modulating the filter or FMing the oscillator!

Envelope generator
Microvolt 3900 has a four-stage envelope generator with independently adjustable attack, decay, sustain and release stages that shapes incoming gate signals to produce a more expressive instrument. The ADSR output can be used to control the amplitude of an oscillator, the cutoff frequency of a filter or any other voltage-controlled function.

Inverting mixer / splitter / offset
An extension of the patch bay, this flexible circuit works as a ±5 volt CV source, signal attenuator/inverter, 2-channel audio or CV mixer, and audio or CV signal splitter.

39-point patch bay
Override the internal wiring and unlock the unlimited audio and CV signal routing potential of Microvolt 3900 for maximum creative control. Fully modular patch bay allows almost every function of Microvolt 3900 to be controlled with patch cables.
