The amplitude of input 1 is compared to input 2 and when the difference is less than the window size, the output is high

Add some interest to an oscillator as a sidechain processor that creates frequency tracking non-linearities.

This deceivingly simple circuit can be used in many configurations:

Pulse wave generation with new flavor of voltage controlled PWM shifting between root and one octave up

Generate (multiple) sub-period events

Create evolving rhythmic patterns

Add looping to any re-triggerable envelope with voltage control over the loop point

Use with an envelope to create a voltage controlled event delay

Tips & Tricks

Don’t forget to patch feedback!
Connect 1/2 gate outputs to an attenuated CV input on the speed of one of your signal sources. For a more dynamic patch, connect the pitch output to it.
Connect the divide gate output to a kick drum and the remainder gate output to a hihat. Now set the counter to 4 and you get a loop of 1 kick then 3 hihats. Adjust the divider setting manually or with CV to vary the ratio of kicks to hihats.
Connect the Coherence gate out to an envelope of one voice, and the Divider gate out to a 2nd voice with pitch out to both, but inverted to one of them. This provides a synchronous parallel event stream.
Although Coherence is a complex module, you can also use it in more simple ways such as a logic inverter, clock divider, gate to trigger converter, or manual 5v source.
Take the envelope output from one side of the Pingable Envelope Generator to input 1 or 2 on Coherence, and set the ping to multiply by 5. Connect the divider gate out to the ping input on the PEG and set the divider to 6. We now have two algorithms driving each other with one multiplying, the other dividing, and separate modulation inputs for each one! With the Coherence divider set to 6 the rate should slowly fall. If you set it to 5 or 4 it should start to speed up again. These speed changes are due to tracking errors between the two systems. It should be noted that window size impacts this behavior.
For more repetitive patterns, resync one or more of the input signals. this could be done by connecting the end of fall pulse on the slower input to a sync input on the faster input. another option would be to take the divider output from coherence so the resync happens after X number (modulatable) of coherence events. a third option would be to use the reset pulse from a sequencer.
Instead of using 2 periodic signals at the inputs, try changing one to be semi-periodic. Use an envelope that is manually triggered, or triggered from a sequencer. Alternatively you could use that envelope to open a vca to let a signal pass only at certain times. This configuration allows a basic melody to be set up with the periodic signal and the dc offset control on input 1, then add variation at specific moments.
