The Ocean of Sound

For all creatures in the ocean of sound - Sonic textures from other worlds, Analog signature sounds, Cut-through-the-mix leads and silkily smooth pads: POSEIDON sets a new standard for sounds and ease of use. All of this was made possible through a combination of the familiar, conceptual simplicity of the analog synthesis and our new, F-Domain synthesis technology.


At first sight POSEIDON looks like a simple structured analog “Oscillator-Filter” synthesizer with all controls visible at once. This gives POSEIDON the ease of use with nearly no learning curve. The real power is working under the hood: The oscillator is nothing less than the award winning spectral modelling sound generator of CUBE. The variable slope Filter is a completely new design based on our unique F-domain synthesis. But let´s go step by step...

Spectral model oscillator

Select a basic sound model from over hundred delivered with POSEIDON. The basic sound model determines the sound characteristic you want to start: taking a artificial model like “Sawtooth” gives you analog style sounds. Use complex models from analyzed samples for earth shaking ambients and evolving pads.
Analyze your own favourite samples to create new models. For really fat sounds use the unisono mode giving you up to eight oscillators with variable detune.

Time manipulation

POSEIDON gives you complete control over the temporal evolution of a complex sound model: time stretching, manual time control and freezing made simple with an unprecedented quality!

Model parameters

High level controls allow for changing the spectral shape, the harmonicity and balances the level of residual noise and spectral amount of the oscillator model. The inherent sound movement can be blurred in time.

F-Domain Filter

The newly developed F-Domain filter allow for drastic changes in the resulting sound spectrum. Five filter types including lowpass/highpass characteristic can be used to shape the sound. They have the usual controls like cutoff but also very unusual ones like a variable slope ranging from 0 dB to 72 dB / Octave and independent controls for resonance and bandwidth! This kind of controls are only possible in the context of our F-Domain synthesis technology. This results in an extremely clear filter sound with breathtaking fast modulation possibilities.


This simple control gives your sound a distinctive moving distribution in the stereo panorama. Every atomic sound particle has it´s own path through the space !

Sound browser

The sound browser in POSEIDON gives you a fast selection of sounds based on five search criteria: sound category, timbre expression and style. But POSEIDON´s browser doesn´t stop here. The current selection can also be used to generate random new sounds fitting the selection you´ve made !
