This circuit takes two input signals and divides them down by /2, /4, /8 & /16. It also XORs the two signals and all of their divisions. All of these individual signals can then be mixed to create the output waveforms. If this is done at audio rates the output is very thick and full of shifting harmonics. If it is done at LFO rates, the output is a complex pattern that can be used as a CV source.

To sum up, it is a dual sub-oscillator, harmonic divider, harmonic ring-modulator and pattern generator.

The best effect at audio rates is to get signals from 2 VCOs that are beating – running at almost the same frequency…but not quite. This gives a continuously shifting and active sound. As the input signals are divided down to /16, it is best to run the VCOs at higher frequencies than usual to be able to exploit all the available divisions.

To use as a pattern generator, connect two gate/trigger/LFO signals to the inputs (or just one – it will still work, but 2 is more interesting). Connect the output to a VCO and adjust the pots to find patterns that will be somewhat unpredictable but quite fun to use. The divided down logic signals are also available on the panel. AThis PCB can be used in 4U systems as well.
