"Here's the first prototype of my tabulaRasa wavetable oscillator module. Making progress on the tabulaRasa hardware – ordered the second prototypes from dorkbotpdx today. More soon."

follow-up to this post where you'll find a video of the breadboard version.

tabulaRasa: Arduino Shield Wavetable Oscillator - Cycling Waveforms

YouTube via surgesg | October 26, 2010

"The tabulaRasa is a Wavetable Oscillator on an Arduino Shield. Users can design and load their own waveforms.
Here, the oscillator cycles through 11 custom waveforms.

tabulaRasa is currently in development...

Arduino Wavetable Oscillator Demo

"Using an Arduino, voltage-to-frequency converter, and digital-to-analog converter to make a wavetable oscillator. The sinewave output is stored in a memory array on the Arduino, and read out at varying frequencies - which are determined by a voltage input. See more at http://www.gregsurges.com/"
