repro - Two classic analogue synths recreated

Two classic analogue synths recreated



Repro dives into the past for analogue inspiration, meticulously modelling two famous synthesizers. Every detail of the original was captured using component-level modelling technology to create the most authentic model possible. All the subtle characteristics and quirks found in the originals are present in Repro. One product, one installer, two synths.

Repro contains Repro-1 and Repro-5 plug-ins.

Sights and sounds

Two in one

Repro-1 is a fierce monosynth: hard working, raw sounding and immediately playable. The classic design is simple and intuitive but belies a deep feature set capable of a wide range of sounds.

Repro-5 is the new polyphonic addition. It has a lot in common with Repro-1, a similar design and feature plus shared sonic DNA. But Repro-5 introduces new flavours, most notably is ability to play lush chords or thick unison leads, while keeping the authentic analogue sound.
