Panner Waveform Generator

Posted on Feb 7, 2013

This device is a microprocessor controlled waveform generator that can be used for driving a voltage controlled stereo panner for music applications. Panning is simply the movement of a mono audio signal between the left and right channels of a stereo sound system . The circuit can also be used to drive other voltage controlled modules that are used in analog music synthesis. The output of the waveform generator is a 0-10V DC control voltage. One of eight waveforms can be selected using an 8 position BCD switch. Waves include: ramp, triangle, sine, cos(x)*sin(5x), damped 4 cycle sine wave, and pseudo random.

Other waveforms may be substituted by changing the assembly language waveform tables. The waveform generator runs in an asyncronous manner, int can be syncronized with other devices by use of an external (5V logic) sync signal or a manual sync trigger
