Pittsburgh starts pre-orders for Microvolt 3900 modular synthesizer

Having showcased its latest offering the 2018 NAMM Show last month, electronic instruments-maker Pittsburgh Modular Synthesizers has announced that it is taking pre-orders for its Microvolt 3900 semi-modular synthesizer.

Thanks to Pittsburgh’s new temperature-stabilised, dual-VCA (Voltage Controlled Amplifier) oscillator core, the analogue audio engine of the Microvolt 3900 feeds a set of timbral wave-shapers carefully crafted for deep harmonic shaping, allowing a layer of additive synthesis alongside the classic synthesis waveforms.

Waveforms are fed into the binary filter, a custom state-variable filter architecture allowing for near-infinite resonance – with or without self-oscillation.

Pittsburgh’s new dynamic VCA lies at the heart of the Microvolt 3900. Whereas a standard VCA works in two dimensions, the dynamic VCA technology adds a third dimension. When the dynamic VCA closes, decreasing the amplitude, harmonics are removed from the source. Whereas when the dynamic VCA opens, the harmonics are restored. This mimics the behaviour of sounds in nature. The result is a lively, organic-sounding synthesizer, full of energy.

The Microvolt 3900 includes a 39-point Eurorack format-friendly 1/8-inch jack patchbay for complete signal routing control over a full complement of audio and modulation options.

On top of that, a highly-tuned, four-stage envelope generator; multitasking function generator, wide-ranging lfo, chaotic random source, multi-mode sequencing arpeggiator, and MIDI-to-CV control are also available.

The Microvolt 3900 is scheduled to ship to Pittsburgh Modular Synthesizers’ global network of authorised dealers and resellers on April 27th 2018, when it will become available to purchase with an RRP of $629.
