MIDI | Klangstrom Documentation

KLST_PANDA features a so-called analog or serial MIDI interface for intput and output via two audio jacks ( see Technical Specifications ):

㉑ :: MIDI out ( analog )
㉒ :: MIDI in ( analog )

void midi_note_on(uint8_t channel, uint8_t note, uint8_t velocity);
void midi_note_off(uint8_t channel, uint8_t note, uint8_t velocity);
void midi_event(SerialDevice* serial_device);

bool midi_init();
void midi_deinit();
void midi_send(const uint8_t* data, uint16_t length);

@TODO( MIDI is missing some callbacks basic callbacks like midi_sysex, midi_control_change, midi_program_change and clock functions )

note, that there is also a USB-based MIDI interface, that allows to connect the board as a USB device to a host or act as a host for USB MIDI devices.
