Using MIDI

Here is a simple MIDI sketch.  It works with this MIDI shield that uses the Tx pin (D1):

You will need to download the latest ShieldBuddy software to get the MIDI's 31250 bit/s! Overwrite the Core 0 setup() and loop() but do not touch the Core 1 and Core2 equivalents otherwise it will not compile.

/*** Core 0 ***/

void setup() {
// put your setup code for core 0 here, to run once:

Serial.begin(31250); // Midi Baudrate

}

void noteOn(int cmd, int pitch, int velocity);

void loop() {

// play notes from F#-0 (0x1E) to F#-5 (0x5A):
for (int note = 0x1E; note < 0x5A; note ++)
{

//Note on channel 1 (0x90), some note value (note), middle velocity (0x45):
noteOn(0x90, note, 0x45);
delay(100);

//Note on channel 1 (0x90), some note value (note), silent velocity (0x00):
noteOn(0x90, note, 0x00);
delay(100);
}

}


void noteOn(int cmd, int pitch, int velocity)
{
Serial.write(cmd);
Serial.write(pitch);
Serial.write(velocity);
}
