hertz donut

Voltage-controlled digital oscillator, with a focus on higher-resolution output with realtime modulation from internal and external sources.

A prototype has been constructed. More information and sound clips will be available soon as the firmware takes shape. The prototype was exhibited at NAMM 2008 and valuable feedback was obtained.
