From the project
Eurorack 4 voice effects processor based on STM32H563
Quadmod is a Eurorack modular four channel effect module. A modulation section allows either phasing or flanging followed by a delay. As part of the Mountjoy Modular polyphonic range the module uses a series of intermodulation paths to convert a four channel input to a stereo output.
Quadmod uses an STM32563 microcontroller which controls a four channel Audio Codec (AsahiKasei AK4619) using SPI for configuration and SAI (Serial Ausio Interface) peripheral to manage the 4 in and 4 out I2S audio streams. The microcontroller reads the front panel controls with internal 12 bit ADCs.
