Help with MIDI Library

Projects Programming

Hi,

I am building a solenoid orchestra and am using the MIDILibrary found

here: Arduino Playground - MIDILibrary

Im trying to have something like Ableton to trigger 6 solenoids through MIDI. Each note would trigger a specific solenoid.

I have built the circuit but am having troubles reading MIDI from within Arduino. Can someone help me decipher how to use the this library? How do I access the note of an incoming message? The help file is not much use to me.

Without using Midi library, you can test with this sketch :

//variables setup
byte incomingByte;

int statusLed = 13;   // select the pin for the LED


//setup: declaring iputs and outputs and begin serial
void setup() {
  pinMode(statusLed,OUTPUT);   // declare the LED's pin as output
  Serial.begin(31250);	  //start serial with midi baudrate 31250 
  digitalWrite(statusLed,LOW);
}


void loop () {
  if (Serial3.available() > 0) {

    incomingByte = Serial3.read();

   if (incomingByte != 0xFE)
    { 
      Serial.print("MIDI IN !");
      Serial.println(incomingByte, HEX);
    }
    // wait for as status-byte, channel 1, note on or off
    if (incomingByte==0x90)
    { 
      digitalWrite(statusLed, HIGH);
      delay(20);
      digitalWrite(statusLed, LOW);
      delay(1);
    }

  }
}
