SampleScience Modular Synth VCO, free virtual instrument plugin for mac and win

SampleScience Modular Synth VCO is a new free virtual synth instrument based on sampled waveforms from the Doepfer A-110-1 analog oscillator.

According to the developer, it emulates the distinct sonic character of this module.

it’s designed to evoke a sense of nostalgia while enabling diverse sound exploration, this instrument caters to both lo-fi enthusiasts and those seeking a range of new textured tones.


The core consists of an oscillator with all 4 VCO waveforms (rectangle, sine, triangle, and saw) that runs through a multimode filter with lowpass and highpass. From here, it goes into an amp (VCA) with three ranges and a multi-FX processor. You can find a distortion, delay, chorus, and reverb.

A multi-wave LFO and a straight ADSR envelope are available for adding movement to your sound. Sounds can be played in three voice modes, including monophonic, legato, and polyphonic. There is also a built-in keyboard.

The plugin does not have the scope of a prominent popular soft synth like Serum or so, but you can quickly get analog-style sounds here. And thanks to the built-in filter, and effects, you can tweak the sounds in different directions. So they are not super fixed.

SampleScience Modular Synth VCO is now available as a free download with the option to donate voluntarily. It runs as a VST, VST3, and AU plugin on macOS (Intel + native Apple Silicon) and Windows.
