From the project

Software to Hardware Prototyping for Eurorack using C++, Max/Gen~ or Faust

This block is a simple 3V3 gate output compatible with Eurorack levels.

It is adapted from the Mutable Instruments Frames schematics.

This block provides a standard eurorack jack connector that is used for eurorack gate output +5V signals.

This module needs to be connected to the +12V and GND lines from the power block.

All GND pins are internally connected in the block.
