Contrenot

The Contrenot (pronounced "con-truh-no") is a musical interface designed to loosely emulate the mechanics of a bowed upright bass. It's inspiration comes from other electronic musical interfaces such as the Ondes Martenot, the Gametrak (as used by SLORK), and the Omatone. The Contrenot has a form factor similar to that of an electric upright bass. The neck consists of a high-resolution linear softpot and FSR for monophonic pitch and aftertouch detection. The body houses a pull-string sensor, created from a gutted tape measure spring, a high resolution incremental rotary encoder, and custom 3d printed parts. The pull-string sensor is able to detect velocity and motion very precisely, allowing for very nuanced control similar to bowing a bass. All sensors and components are powered by an Arduino Uno. Data is sent over USB serial to a Linux computer, where it processed and mapped to sound parameters in Sporth, a stack-based audio synthesis language.
