Repro-1: A reverent emulation of a famous vintage synth. All the quirks and personality of the original captured using component-level modelling for a truly authentic analogue sound.

Product details

A classic design with fierce capabilities: two-pattern step sequencer, self-oscillating filter, arpeggiator, a unique modulation section, five stomp-box effects … and proudly mono like the original.

Mix oscillator waveforms, add white noise or feedback, dial in rich LFO-driven pulse width modulation or try out the sync and cross-modulation options. To experience Repro-1’s aggressive side, push the filter resonance over the edge—you will soon discover that Repro-1 is a wolf in sheep’s clothing
