Repro1 Electron

Repro1 Electron


The Repro1 Electron delivers an unparalleled experience by maximising the potential of u-he Repro1. The package includes 132 detailed and tagged presets, but the Synthmorph sequences are the heart of the matter.

First, briefly about the Repro1 Electron presets: as usual, almost all presets use pre-mapped controllers (typically modulation wheels, and sometimes velocity and aftertouch), so you can use the instant modulation options expressively right away in your own DAW application.

And the magic is further enhanced by the use of Synthmorph sequences and layers

As Repro1 itself has a simpler structure, you can fiddle with fewer parameters in the Synthmorph sequences (usually between 11-16), compared to other synths. Still, in the case of Electron presets, modulating these parameters in parallel generates a swirling kinetic energy in the audio domain that will make any electron particle detector go haywire!

20 full morphing custom Synthmorph sequences (some of which you can hear in the video) are available in both in .MID and .WAV formats.

As a further development of the Synhtmorph concept, the same 20 phrases are now also available as so-called "CTRL ONLY" sequences, where only the parameter modulations are run while you play the keyboard live on the original (or any other!) patch. This reveals an amazing world of possibilities where you can actually achieve more usable preset variations, while also having the joy of exploring and creating your own unique presets.

Finally, although the Repro1 is a monotimbral and monophonic instrument, layering presets adds a new sonic dimension. For the quick start you get 15 matching preset combinations, playing simple one-fingered melodies or trigger notes, which usually means playing 3 different MIDI parts for 3 separate Repro1 instances. You access these 15 layered example sequences in their original MIDI and WAV formats: modify the sounds that make up the layering, and use them to create additional variations of your own.

There's little point linking presets to genres these days, so for now we do not make any style-specific listing. Listen to the demo and decide for yourself how these sounds and sequences fit into your own musical world.

If you want to feel the movement and the pulsating plasma energy of the audio, the dynamics of the emotive sounds, then check out Repro1 Electron!
