Finished Pieces


    The Benjola is a kit format adaptation of the Benjolin synthesizer.
    It has been designed to be easy to assemble and modify and I’ve added a few cool new features along the way.
    This project is officially sanctioned by Rob Hordijk, the inventor of the Benjolin.

    The Benjola is a deceptively simple analog circuit capable of generating a remarkable range of abstract, melodic and rhythmic sounds.
    It is made up of a small number of modules:
    -Two voltage controlled triangle & square wave oscillators
    -One resonant 2-pole state variable filter (with a few tricks according to Rob).
    -A voltage controlled lo-fi echo.
    -A chaotic pattern generator invented by Rob called a “Rungler”.




    The rungler is the beating heart of this instrument and is somewhat difficult to explain. Rob talks about his “deluxe”rungler synth module
    in the video below. The design in the Benjola is a bit different than the one in the video but the core functionality is the same.


    Sorry, no sound files for this piece.
