The Toppobrillo Sport Modulator 2 is a fully analog, patch programmable Eurorack module designed to do a wide range of functions from a few basic elements.

At it's core the module is two channels of slew into sample/track & hold with a comparator circuit linking the two. The slews have voltage control over rate (both rise and fall) and have an end of rise gate output. When self cycled each channel can be configured with jumpers to be unipolar (0 to 10v) instead of the default bipolar (5v to +5v). Each channel has a gate input that allows you to snap the output to 0v. There are two CV inputs per slew (CV1 has an attenuverter while CV2 is tuned to 1v/oct). The comparator circuit outputs +5v when the top channel is outputting the higher voltage and 5v when the bottom channel is outputting the higher voltage. This comparator is linked to the sample & hold input of the top channel and the slew input of the bottom channel.
