From the project
Software to Hardware Prototyping for Eurorack using C++, Max/Gen~ or Faust
This block is a simple analog CV input. Its design is detailed here.
- This block needs its GND to be connected to the ground. All GND pins are connected internally, - This block needs its -12V to be connected to the -12V of the power-bus, - This block needs its 3V3A to be connected to the Daisy Seed 3V3 Analog Power I/O on Pin 21, - The NOP pin can be either connected to: - GND to send (slightly noisy) zeros to the software implementation, - Cascading the DI signal from another cv-in block, - A pseudo-random predefined signal to detect a jack connection as explained on the Mutable…
