Phazor is a free effect plugin, which emulates the phaser effect found in the Virus synthesizers, which helped make its characteristic sound. A lot of time was devoted to make it sound very close to the original and every control has been carefully adjusted to behave just like the phaser from the Virus. It has selectable 1 to 6 stage all-pass filters controlled by an LFO, with spread and feedback controls. The plugin is highly optimized and its CPU usage is minimal, allowing for multiple instances to be used in a project.

Credits go to J. Bradford Hunter for his help with the coding and optimization!



Available for Mac and PC, 32 and 64 bit. Ported by Andrey Starostin.

    Why no Mac and 64-bit version? Unfortunately, SynthMaker does not yet support export to 64-bit or AU, Mac VST yet. As soon as SynthMaker supports them, the effect will be available in these formats.

    Hi Adam,

    I was looking for a good phazor like it for a while, simple to use and very effective 🙂

    Can you add a midi lfo sync and your phasor will be perfect. I will use it on my next album for sure :).

    Perhaps you next project will be Characters another great Virus Ti effect.

    See you and thanks again.
