Harmony and Sound

A surprisingly versatile tool.

Obscurium animates you to explore new paths to creation of music & sound design. Like a modular system, it allows for most complex circuits, yet remains easily accessible.

It will change your process of making music, to a fun and playful state of flow and you’ll come up with patch after patch of cool melodic and chordal passages that intiate new tracks. Never mind the possibilities of the VST synth integration!

If you are sound designing for films, adverts or games, if you are looking for a fresh short cut to your creative cloud, give it a go!

Here’s a quick walkthrough by the great Tom Cosm:

Sound Design Playground

Obscurium's scope can only be matched by very large and costly modular setups

The two sound generators are deceptively basic looking. Number 1 is an emulation of an analogue oscillator with an unisono functionality. The second oscillator uses FM synthesis with a flexible ratio. Both can be routed through the effect section and you can mix and modulate them via the sequencer. Ask Audio's Quick Tip

The Super Obscure Mode automatically draws sequences in most various ways. The Modifiers paint all parameters at once: while setting individual steps you can define their sound. Step by step a different sound – this is the agenda here.

VST interface

Resurrect your library of long-forgotten plug-ins

You can host any of your sound generator VST2 plug-ins for fresh sounds. Obscurium sends trigger, pitch and 11 automation lanes. Take your plug-ins to new levels!

Setting this up couldn't be easier - pick any of the plug-in's presets, use a random mode to assign parameters or use the Learn function in Obscurium's hosting options.

In this video, Tom uses Sugar Bytes "Cyclop" as an example: „Cyclop“:

Shift and Morph

The more you play, the more you discover.

We implemented the unique possibility to rotate parameters and their motion lanes. Organic and complex sound changes just blossom around you with a tender touch of these faders. This feature can be modulated for endlessly evolving results.

Additionally you can morph between two sequencer states (copy and paste between the two states is very useful!). That makes it possible to vary parts of a sequence while it repeats.

Obscure Clock

A Warp drive to the new dimension of sequencing

The clock tab regulates the master speed, swing & direction. Combine its 2 mini sequencers for clock and direction with the main sequencer for finest colorful rhythm tapestry.

Sequencer steps can be assigned to MIDI notes, playback speed and direction might change at any time. A different sound for each note of a melody and tumbling rhythms, rolls and triplets, ready to be explored.

Sounds & Presets

An instrument with a mind-boggling scope

Rummage around in these sounds...They give a pretty good idea of what Obscurium is capable of. Better yet: check out the demo - the modulated presets are a feast for ear and eye.

The presets are a good inspiration and starting point for your own ideas. Obscurium invites you to experiment!

”We can't think of a synth that makes it easier or quicker to create complex, unique patches, and as the selection of over 400 presets demonstrates, it's surprisingly versatile. It also sounds great, offering warmth, punch, bite, edge and smoothness in equal measure and then there's the ability to incorporate third-party instruments, which obviously extends the shelf life immensely. 10/10”

”Am meisten imponiert mir, dass Sugar Bytes den Spagat zwischen komplexen Pop-Hit Presets und wundervoll abstrakten Klangwelten schafft. Obscurium ist, ganz ironielos, ein extrem hippes Plug-in.”


”Obscurium empfiehlt sich nicht nur als experimentelles Sounddesigner-Tool für Produzenten elektronischer Musik. Insbesondere Musikschaffende aus der Game-, Werbe- oder Film-Branche sollten sich das Plug-in unbedingt mal genauer anschauen.”

Professional Audio Magazin

”Your Frankenstein has changed my life: I've been producing music professionally for almost 15 years, but Obscurium has been the game changer I've been waiting for my whole career. Since its release, my process of making music has drastically changed. It has become more fun and playful and my creativity and efficiency has just skyrocketed because of this tool.”
