Repro dives into the past for analogue inspiration, reverently modelling two classic synths. Every detail of the originals were 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.

Repro-1 is a fierce synth: hard working, raw sounding and immediately playable.

Repro-5 shares sonic DNA with Repro-1, but offers new flavours and features, most notably polyphony.

Repro-1 Key features:

  • Unashamedly monophonic.
  • 4-pole resonant lowpass filter.
  • Glide control.
  • Arpeggiator with latch mode.
  • Sequencer with two 32-step patterns (or 64 steps when chained).
  • 3 modulation sources controlling 5 destination.
  • 2 additional "performance" modulation assignments.
  • 5 effects: wavefolder/distortion, delay/chorus, EQ/resonator, reverb, sonic conditioner/dynamics processor.
  • 500 factory presets.

Repro-5 Key Features:

  • 8-voice polyphony.
  • 1 to 8 voice unison with glide control.
  • Audio-rate voice modulation: oscillator FM (frequency and pulse width), filter FM.
  • 4-pole resonant lowpass filter.
  • Flexible modulation options plus 2-slot matrix.
  • Polyphonic distortion unit with 4 types including bit crusher.
  • 5 effects: tape emulation, delay/chorus, EQ/resonator, reverb, sonic conditioner/dynamics processor.
  • Over 950 factory presets.

Common Key Features for both synths:

  • Powerful analogue sound using component-level modelling.
  • 2 oscillators: saw / pulse and saw / triangle / pulse.
  • Oscillator waveforms can be combined.
  • Waveform pulse width modulation and oscillator sync options.
  • White noise generator.
  • ADSR envelope.
  • "Tweak" screen for adjusting component behaviour.
  • Host-syncable LFO with 3 waveforms.
  • Microtuning support (.tun files).
  • Resizable UI.
  • MIDI learn page and editable list.
  • Global preferences page.
  • New preset browser with powerful search functions, tagging.

An amazingly organic-sounding synth, and a two for one value. I came across U-he mainly as I'm a Linux user and I've ended up purchasing almost everything they make.

Repro-5 is the best sounding software synthesizer available today (20/08/2018).

The trade off is a really high CPU usage.

It's really easy to make good sounding presets, the stock ones are better than average softsynth presets but still not as good as in some hardware keyboards and synthesizers.

Still, I can't give it less than 5 stars just for the sound that it delivers.

ONe of the best synth here, .

the sound is incredible, .

when Repro will be fully mpe compatible, it will be the ultimate analogue emulation.

2 synths for the price of one .

One of the best and most realistic emulations around. For classic synths in software, U-He is one of the few no-brainers. And with Repro, you get two synths in one.

Amazing sound, the most analog sounding synth I ever heard. Its easy to create original patches too. Its a bargain now it also comes with Repro-5 for the same price.

Its heavy on CPU though. Give the demo a good try to make sure your computer can handle it.

Is it just me or a monosynth model for $100 is a really niche market? :)

6 December 2016 at 7:11pm

Depends. Some companies were more successful with mono synths than with their poly stuff. Try the demo and maybe you'll see why.

28 August 2017 at 8:59pm

I have gotten $100 worth out of it in under two weeks. I love it. I love all u-he's stuff, but this has quickly become number one! Plus, basses, arps, leads and even some pads are monophonic by nature, so being monophonic is really not as limiting as you might think. And I imagine you already own oodles of polys, as do I. What you're paying for with this is character, and it has it in bucket loads. And frankly, I actually like being limited to monophonic in a lot of cases. It forces me think in a different way.

And lastly (this should be the kicker for any fence-sitters out there), word on the street is that Repro-5 (a polyphonic synth based on the Prophet 5) will be free for Repro-1 owners.

I tried the demo. It was good. Not too taxing on CPU, friendly interface, and crisp sounds. It is on par with u-he's other offerings (it is well-made).

This and Bazille seem to suit me perfectly --though still using the CM and Beta versions. Can't wait to finally get a full version of this.

Repo 1 and 5 are just plain awesome! So good to have them both in the arsenal.

Repo 1 / the Sequential Circuits Pro-One and its multitimbral bigger brother was used by so many artists and notorious bands and it has been so convincingly reproduced on the software side by u-he...it's pure joy to use them.

On par with that kind of quality emulation of a hardware Synth only the OBX-II PRO comes in mind.

Have fun.

Repro 1 & Dune 3 doing a silent revolution in synthesizing, quality - it's all about this synths, they both can kill any Hardware or sofware synth for now.
