.COM is a comparator and divider network configured for audio applications. Think of it as an elaborate version of the pwm and suboctave of the sh-101. Or if you're not familiar with the sh-101, think of it as a little box you can put any waveform into and get a pulse wave and 4 varieties of suboctave from.

  • The signal input is where you would put whatever you want to turn into a pulse wave into.
  • The threshold control sets the "flip" point of the comparator, and has a range of approximately negative five volts to positive five volts. Think of it as a pulse width control.
  • The threshold input is summed with the manual control, and allows for external modulation of the threshold point. Think of it as a pulse width modulation input.

Next are five outputs. They are all ten volt peak-to-peak signal to play nice with other audio modules. This is unlike the sh-101, where the suboctave had a dc offset which made its bass frequencies not as strong as they could have been.

  • The first is the direct output of the comparator. In pulse width terms this is zero to one hundred percent.
  • The second output is a 50 percent duty cycle wave one octave lower than the main output.
  • The third output is a variable output, from one to forty-nine percent duty cycle, one octave lower than the main output.
  • The fourth output is a 50 percent duty cycle wave two octaves lower than the main output.
  • The fifth output is a 25 percent duty cycle wave two octaves lower than the main output.
