POV DJ’s and music produces want to have fun with their music and this tool allows them to be physical and create effects. Each stacked disk controls an effect in PD (or MAX or other music production/effect platforms) that can alter a prerecorded track or create a new sound using waveforms, filters and other effects.
concept O3 uses three stacked disks to control an effect in PD (or MAX or other music production/effect platforms) that can alter a prerecorded track or create a new sound using waveforms, filters or other effects. O3 uses very sensitive Yumo Rotary encoders (1024 P/R) and an Arduino Mega to translate precise movements into sound. The Encoders report Quadrature data which is converted into data that PureData can read using custom firmware. See how it works here or by clicking the first image above.
mechanics This prototype uses stacked disks, a case and gears custom designed in Solidworks and laser cut from 1/4″ acrylic. Each disk is connected to a gear that is mated to a gear attached to an encoder. The gear tooth ratio allows for high definition feedback and control.
