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.

    Excellent ergonomy, nice sound ! I wish, Adam, that you’re working on other Fx, delay, reverb, etc., because I like you way to design this phaser. Bonne continuation !

    Sounds really good, but crashes Cubase all the time when I try to change the preset. Default preset works, I can change parameters, but when I switch to the next preset, sound mutes, and if I desactivate/reactivate the plugin, I get a general Cubase crash. Can you do something about it ?

    This effect does sound really nice but there is something wrong with the presets like Paupaul said. It would be terrific if you could find a workaround. Thanks.

      Michal Janowski 05/05/2010 at 10:38 am Hey,No problem. I can keep the tmtelape project you’ve provided, and import it into another project as a precomp and then tweak the ellipses myself. This is still a huge timesaver.Thanks for the cool stuff It is really impressive.Cheers,Michal
