From the project
Software to Hardware Prototyping for Eurorack using C++, Max/Gen~ or Faust
This block is a simple analog audio input for the Daisy Seed onboard codec. 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 -12 to be connected to the -12V of the power-bus, - This block needs its +12 to be connected to the +12V of the power-bus, - The NOP pin can be either connected to: - GND to send (slightly noisy) zeros to the software implementation, - Cascading the DI signal from another audio-in-daisy block, - A pseudo-random predefined signal to detect a jack connection as explained…
