What it is

Repro is a synthesizer plug-in containing Repro-1 and Repro-5 in one product and installer. Repro-1 models a monophonic analogue keyboard and can step-record two patterns of up to 32 notes each. Its five rearrangeable effects include a wavefolder, delay, EQ/resonator, reverb and sonic conditioner. Repro-5 supports up to eight-voice polyphony or unison, with optional glide, and includes more than 950 factory presets and a polyphonic distortion unit with four modes, including a bit crusher. The product runs on Linux, macOS and Windows, but is not standalone and requires host software; it supports nearly all DAWs. The listed plug-in formats include CLAP, AUv2, VST3 and AAX on macOS, and VST3, CLAP and AAX on Windows. Repro is NKS-ready and compatible with Maschine and Komplete Kontrol hardware. The listed Repro plan costs €149 as a one-time purchase, and a free trial is available; its demo emits a crackling sound. Linux builds are beta and receive less support than macOS and Windows versions.
