Critic Reviews

Pittsburgh Modular Microvolt 3900

soundonsound.com

Pittsburgh Modular's Microvolt 3900 is a sonic playground for the experimental musician, packing an impressive array of features into a compact, semi-modular synthesizer. Its standout Low-pass Gate and modulation options invite creative exploration and unexpected soundscapes. However, the unit's esoteric design choices and error-laden manual make it less accessible to newcomers. While the synth's lack of VCAs and mixers limits its standalone capabilities, it excels as a supplement to a larger modular setup. If you're after a quirky, feature-rich synth for sound experimentation, the Microvolt 3900 is a compelling choice.

Pittsburgh Modular Microvolt 3900 review | MusicRadar

musicradar.com

The Pittsburgh Modular Microvolt 3900 is a standout semi-modular synth with a unique blend of 'East Coast' and 'West Coast' synthesis styles. Its compact design doesn't skimp on character, offering a dual-mode VCA and a binary filter that can be both smooth and gritty. Although the absence of sequence saving and the initially confusing filter resonance could be drawbacks for some, the synth's sound engine is both inspiring and characterful. The 39-point patchbay, while not the most extensive, is intelligently designed to maximize creative possibilities. Overall, it's an impressive package for those looking to explore semi-modular synthesis.

Review: Pittsburgh Modular Microvolt 3900 : Ask.Audio

ask.audio

The Pittsburgh Modular Microvolt 3900 is a robust semi-modular synthesizer that impresses with its intuitive design and rich sound. Its blend of east and west coast synthesis, coupled with 39 well-organized patch points, makes it a versatile choice for both newcomers and seasoned modular enthusiasts. The unique random source and powerful arpeggiator are standout features, adding depth and creativity to sound design. However, its delicate sliders and somewhat confusing MIDI/Clock section may require careful handling and a learning curve. Despite these minor drawbacks, the Microvolt 3900 offers substantial value and flexibility, making it a compelling addition to any setup.
