Repro captures the essence of vintage analog synthesizers through detailed component-level modeling, faithfully recreating the unique sound and character of two iconic synths. This approach ensures every nuance and quirk of the original hardware is authentically represented, offering musicians a rich and expressive sonic palette. The collection includes two distinct instruments: Repro-1, a monophonic synth known for its raw and immediate tone, and Repro-5, which expands on this foundation with polyphonic capabilities and additional features.

Repro-1 delivers a powerful monophonic experience with features such as a resonant lowpass filter, glide control, an arpeggiator, and a sequencer with flexible step patterns. It also incorporates multiple modulation sources and a suite of effects including distortion, delay, and reverb, making it an ideal choice for crafting aggressive, dynamic sounds. Repro-5 builds upon this framework by offering up to eight voices of polyphony, voice unison, and advanced modulation options including audio-rate oscillator and filter frequency modulation. Its comprehensive effects section features tape emulation and polyphonic distortion, providing deeper sound design possibilities.

Both synths share a robust set of features designed for modern production environments. These include dual oscillators with waveform combination and modulation options, an ADSR envelope, host-syncable LFOs, and microtuning support. The interface is resizable and equipped with MIDI learn functionality and an enhanced preset browser with tagging and search capabilities. Comprehensive global settings and support for advanced tuning standards ensure seamless integration into any workflow, making Repro a powerful tool for producers seeking authentic analog sound with modern flexibility.
