benjolinMod

In the spring of my Sophomore year at Skidmore College, I began working and collaborating with Peter Edwards, also known as Casper Electronics. One of the projects that came from this time of collaboration was our reinterpretation and construction of Rob Hordijk’s Benjolin circuit. Our version comprised the addition of several original circuits, which served to augment this original circuit, as well as a redesigned faceplate, control interface, and the adaptation of the module into our own synthesizer module format.

The circuit originally featured eight controls and a small patchbay. We extended this to twenty-two linear controls, two switches, seven LEDs and a twenty-five point patchbay. The additional circuits we added include two envelope generators, several input and output buffers to allow better interfacing within a modular synthesizer, and the redesign of the original circuit to breakout many previously inaccesible controls.

Check out the schematics below for the modifications to the original circuitry.
