Additionally, Rex wrote the following to me a while back regarding my ÷N Comparator, and it helped me out a lot!
“Input signal(s) must be in either (or both) of the [comparator] (IN+ / -) blue jacks and the knob directly above them set for the 'optimal' pulse width of the conversion. This resultant GATE out (or pulse stream out) is then outputted from the red jack directly above the knob. [The comparator section] of the function has to be set up BEFORE the [÷N] section with the dividers will work correctly.”
Hope that helps you too!

Subject: Re: [SergeModular] Dual Comp questions
The N com is one of those things you could
write a full article about.
It has two main sections: the comparator and the divider. The comparator
has the same function as each unit in the dual comparator module.
You put a signal into either nput, it compares it to the knob setting
summed with the other input. Its easiest use is making nice square and
rectangular pulses from a sine, triangle or sawtooth. Input an audio
signals into + and -, you get interesting klang tones at the
comparator's output.
Yes, you can use the comparator to make triggers also. The comparator's
output is either high or ground. Use slower signals and trigger signals
in + and - to make trigger pulses.
The divider divides the pulse from the comparator by the /N knob
setting, from 1 to 31. You can use this as a frequency divider. The /N
output gives you one (narrow) pulse for every N input pulses. You can
control the divisor with the knob or a voltage.
The "Step Out" gives you a staircase with N equal-sized steps. If you
have a staircase with 10 steps, each step is smaller than one with 3 steps.
Something I never hear discussed is the pairing of the comparator and
the quantizer. I forget the exact connection, but patch the input of the
quantizer into the + input of the comparator, and the quantizer's output
to the - input of the comparator. Using this, trigger signals will come
from the comparator output every time the quantizer's output makes a
transition. "So what" you say. If you use the quantizer to quantize
slow-moving LFO or random signals, this is a great way to trigger them
as notes.
