BeepBoop Electronics 2hp CMP V2 Eurorack Comparator Utility Module

Generate gates and triggers by comparing two signals. Think of it as a CV controlled logic gate!

A comparator has two inputs and an output. The output goes high when the level of one input exceeds the other. Compare an external signal routed to the input with an internal threshold voltage set by the slider. What makes the 2hp CMP V2 a flexible utility is it is also possible to CV control the threshold as well. This makes it possible to compare two external signals. The internal threshold is set by the sum of the offset slide control and the CV input jack at the top of the module.

The range of the internal offset depends upon the position of the central push button switch.
ON – BIPOLAR MODE +/- 10v range
OFF – UNIPOLAR MODE 0-10v

Getting Started

• Patch the output to any module that reacts to gates and triggers, for example an envelope generator.
• Adjust the offset slider.
• The input signal will be compared with the built in offset (set by the slider and top CV jack) producing a gate at the output.
• The output gate will stay high as long as the input signal level is higher than the threshold voltage.
• Check you are in Bipolar mode. With nothing or 0V patched to the input jack the output will go high as the slider moves past the middle position.
• Now apply a bipolar CV signal to the input labeled IN, for example a triangle wave.
• The output will go high depending upon the position of the slider.
• As we increase the internal threshold the pulse width of the output should get smaller as now only the crests of the triangle wave are higher than the internal threshold.
• Now apply another CV signal to the top input jack labeled CV.
• A new threshold level is now created by combining the slider control offset and the CV signal routed to the top jack. This new threshold is compared with the input jack.
• Using two LFOs patched to the input and CV control will produce gate and trigger patterns depending upon the relationship between their levels but also shape and frequencies.

As well as being very useful for creating interesting rhythms the module also responds to audio rate signals. Create PWM type effects by feeding in an oscillator to the input and another oscillator to the CV input new waveforms can be generated.
