CatSynth TV: Benjolin!

Our latest video features the Benjolin, a module designed by Rob Hordijk and distributed by Epoch Modular.  From the official website:

The benjolin is a multifunction synthesizer designed by Rob Hordijk. The module consists of four separate function blocks: two VCOs, a state variable filter and an additional circuit, invented by Hordijk himself, called a rungler. This particular arrangement emerged from his efforts to design a synthesizer that was, as he puts it, “bent by design”. As such, the module functions according to principles of chaos theory, where short to long sputtering patterns spontaneously transform themselves, at times, gradually, at others, quite suddenly, morphing into new pattern doublings and bifurcations. ​

The rungler is what gives the module (and its predecessor the Blippo Box) its chaotic character.  It’s basically a shift register timed off the two oscillators which then fed as a control signal back to the oscillators, creating a nonlinear dynamic feedback system.  It’s a lot of fun to just play and explore, but I have also used it in both recordings and live performance.  It works particularly well with subtle control inputs, like the Theremini.
