Repro-1 is a fierce mono-synth: The classic design gives you immediate access to all the raw power: Two oscillators, a self-oscillating 4-pole lowpass filter, arpeggiator, step sequencer, the unique modulation section, and five stomp-box effects, which you can arrange in any order. Hardworking, raw sounding and immediately playable, it's a simple and intuitive synthesizer that belies a deep feature set capable of a wide range of sounds.

Features

Tweaks panel

Apart from being unashamed eye-candy, the Tweaks page is there to let you change the fundamental behavior of individual modules. There are 5 user-adjustable jumpers (mini circuit connectors) and 5 module tweak selectors. While on this page, all the main controls of the synthesizer are still accessible.

Besides the option to modify the synth's fundamental characteristics through jumpers and selectors, the panel also includes access to the Microtuning section with many included presets.

Sequencer

The sequencer in the original hardware may have been a stroke of genius. Repro-1's version lets you step-record two patterns of up to 32 notes each, which are also saved with the preset and support copy/paste of pattern's presets between different instances of the plug-in.

Other than having more steps than the original, the integrated sequencer supports per-step velocity, a rest button to add pauses, the ability to record your sequences through a MIDI controller, and other improvements.

Stomp-boxes

Repro-1 ships with a set of 5 high-quality effects in the shape of stomp-boxes. From subtle to extreme adjustments, this section expands the analog synthesizer's capabilities beyond expectations.

The effects section includes Jaws (wavefolder), Lyrebird (a flexible delay, which inspired the creation of Colour Copy), RESQ (semi-parametric EQ or resonator), Drench (a lush plate reverb), and Sonic Conditioner (a stereo saturator and transient designer - to add the right amount of gelatine to your patches). All effects are rearrangeable through drag and drop in the FX Chain section.
