Compare 2 - Dual Window Comparator

The window comparator is a very useful circuit building block that is common in general electronics, but rarely found in modular synths. While a regular comparator activates when the input signal voltage is higher than a threshold level, a window comparator checks if the voltage is between two levels (these form the 'window').Compare 2 combines two such comparators and a logic section in 8 HP. The result is an advanced tool for extracting gates and pulses from analogue signals in Eurorack synths.The detection windows are defined by the shift and size parameters, which can be varied using the knobs and CV inputs. Complementary gate outputs are available, with big three-colour LEDs showing each comparator's status.All inputs are normalised from the left section to the right, but the two comparators can also be used completely independently. On the bottom, the outputs from both comparators are combined in various ways by the logic section, which also features LEDs.You'll find a use for th
