Personatrix for Pure Data

Personatrix is an effects processor, providing sonic tricks to create imaginary characters. Note that this project is in early development and may present issues on your platform. Functionality and user interface may change.

download link


Personatrix needs Puredata ("vanilla pd") >= 0.47. You can download Pd from or (on Linux) install Pd from repository.

Personatrix also needs two external libraries: zexy and iemlib. These can be installed via Pd (menu > help > find externals), or on Linux from repository (pd-zexy and pd-iemlib).

how to use Personatrix

Connect an external mic to your computer for close miking. Open file personatrix.pd in Pd from the menu or by (double)clicking. Select presets with different voice effects through digits 0 till 9.

Personatrix currently has three banks of presets, accessible through the three buttons next to "num" on top of the interface. The other black buttons are reserved for future development.

To modify presets, click button "params" and use the sliders. Click "save" if you want to store your modifications in the preset files on disk. This will overwrite the original settings. No undo! A backup copy of original settings is stored in folder personatrix/abstractions/presets.

Numeric keypad is a convenient controller for Personatrix, otherwise use qwerty keyboard or mouse.
