u-he Repro VST Synth — Two Classic Analog Synths, One Plugin
The u-he Repro VST Synth takes component-level analog modeling seriously. Rather than approximating the sound of vintage hardware, Repro models the actual behavior of individual electronic components — the way the filter clips, how the oscillators drift, the subtle imperfections that make analog synthesis feel alive. The result is a plugin that sounds like the hardware it’s built on, not just a digital impression of it.
You get two complete synthesizers in one purchase: Repro-1 and Repro-5. Both are modeled after legendary instruments and cover different ends of the synthesis spectrum.
u-he Repro VST — Repro-1 and Repro-5 Explained
Repro-1 — Monophonic (Based on Sequential Circuits Pro-One)
- Monophonic architecture with the raw, direct character of the Pro-One
- Excellent for punchy basslines, aggressive leads, and classic synth sequences
- Oscillators: Saw/Pulse waveforms with sync and cross-modulation
- Fast, focused, and full of analog attitude
Repro-5 — Polyphonic (Inspired by the Prophet-5)
- 8-voice polyphony with unison mode and individual voice panning
- Rich pads, lush chord voicings, and expressive vintage textures
- Oscillators: Saw/Triangle/Pulse with fine-tuned analog character
- The polyphonic warmth that defined 70s and 80s film and pop production
Analog Modeling — What’s Under the Hood
Both synths share a 4-pole resonant lowpass filter modeled for analog warmth and smooth musical response. The Component Tweak Page lets you adjust internal behavior that you’d normally only access with a screwdriver on real hardware: oscillator drift, filter calibration, component tolerances. This is what separates Repro from surface-level analog emulations — you can actually tune the personality of the instrument.
Audio-rate modulation is available for oscillator frequency, pulse width, and filter cutoff, which opens up a range of harsh, metallic, or subtly animated tones that standard LFO modulation can’t reach. Polyphonic distortion ships in four types including a bit crusher, which adds character without needing external processing.
Built-In FX Chain
- Analog-style Delay — warm, musical, with natural analog movement
- Chorus — adds spread and movement to pads and leads
- Plate Reverb — classic studio-style spatial depth
- EQ/Resonator — tone shaping and resonant coloring
- Sonic Conditioner — overall tone and character adjustment
- Tape Emulation — saturation and compression from magnetic tape behavior

Why u-he Repro Stands Apart
Most analog-modeled synths nail the broad character of the hardware they’re emulating but miss the smaller details that make the original instruments feel like they’re breathing. Repro doesn’t miss those details. The oscillator drift, the filter self-oscillation behavior, the way the envelope stages interact — it all tracks accurately enough that producers who’ve used the original hardware recognize it immediately.
The 950+ factory presets cover synthwave, techno, R&B, film scoring, and experimental sound design. Individual voice panning in Repro-5 creates stereo width from the instrument itself without needing to add external processing. The unified installer means you get both synths from a single download without managing separate packages.

Frequently Asked Questions
What hardware synths inspired Repro-1 and Repro-5?
Repro-1 is modeled on the Sequential Circuits Pro-One, a monophonic synth from the early 1980s. Repro-5 draws from the Prophet-5, one of the most influential polyphonic synthesizers ever produced.
What is the Component Tweak Page?
The Component Tweak Page gives you access to internal parameters that affect how the modeled components behave — oscillator drift, filter calibration, and component tolerances. These adjustments create the subtle variations in character that make each instance of the synth feel slightly different, just like hardware units do.
Does Repro work in Pro Tools?
Yes. Repro supports the AAX format, making it compatible with Pro Tools on both Mac and Windows.
Do I get both Repro-1 and Repro-5 in one purchase?
Yes. Both synthesizers install from a single unified package. You get the full Repro suite — Repro-1 and Repro-5 — with one purchase.
