Or this:


"A single chip 1V/Oct voltage controlled digital oscillator, with 20 
waveforms in a scannable wavetable.
The VCDO uses a PIC 16F1847 microprocessor to create a versatile and 
simple voltage-controlled 8-bit digital wavetable oscillator. All 
oscillator parameters are controlled by 0-5V control voltages. The chip 
has a native exponential control response, making interfacing with 
1V/Oct control voltages very simple, even without an exponential convertor."
