Interactive Users Guide

In order to better illustrate the behavior of this module we developed a javascript app for potential users to test and better understand the module’s inherent features.

This guide features all the functions of the real hardware module plus a graphical display that resembles an oscilloscope and a very simple sound engine as if the module output was plugged straight into the CV input of a VCO.

The audiovisual experience of using this application makes it a very effective demonstration of the module’s operation.



Also available is the offline Java App cross compatible with the three main operating systems.
