VirSyn - Poseidon v1.4


The new version 1.4 of POSEIDON introduces the exciting PoleZero filter technology for modelling very complex resonant
characteristics with up to 8 bandpass/notch filters.
But thats not all...

News in POSEIDON 1.4


- PoleZero Filter with up to 8 bandpass and 8 notch filter with morph function between two filter parameter sets.
As a result the PoleZero filter can model very complex resonant characteristics, for example acoustic instrument
bodies, the human vocal tract or something that does not exist in nature. Even more you can use two parameter sets
named “Filter A” and “Filter B” to interpolate between two resonant structures in realtime with the “Morph”
parameter. There is also a “Cutoff” parameter which let you move the complete filter structure up and down
in the frequency range in realtime.
- New filter for emulation of analog 24 dB lowpass.
- 50 new presets demonstrating the new filter types.


- Mac/PPC: Crash on image import.
- Timing of MIDI program change messages improved.
- Filterparameter with type sensitive labels.
- Mac: scroll wheel is working now

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.
