// "Sequencer/Advanced/CommonConfiguration" - Changes the common configuration of a `Sequencer` in runtime
//
// This example shows how easy is to change the common configuration of a `Sequencer`
// while affecting all the layers that are being played at the moment.
//
// Setup needed to run the examples: https://github.com/razrotenberg/Midier#setup
// No additional setup is required for this sketch
//
#include <Midier.h>

    // if you are connecting using a physical MIDI connector and cable, set it to 31250
    // if you're not sure what this is, or which baud rate to use: https://github.com/razrotenberg/Midier#baud-rate
