Like Chris L here above I'm having a problem making my Arduino read a poly midi signal.
When I send a MIDI signal from my TC Electronics Konnekt 48 it works fine and polyphonic works, but when I use my MOTU UltraLite it only receives a mono signal.
Here is the code I am using
//variables setup
byte incomingByte;
byte note;
byte velocity;
int statusLed = 13; // select the pin for the LED
int action=2; //0 =note off ; 1=note on ; 2= nada
//setup: declaring iputs and outputs and begin serial
void setup() {
pinMode(statusLed,OUTPUT); // declare the LED's pin as output
pinMode(2,OUTPUT);
pinMode(3,OUTPUT);
pinMode(4,OUTPUT);
pinMode(5,OUTPUT);
pinMode(6,OUTPUT);
pinMode(7,OUTPUT);
pinMode(8,OUTPUT);
pinMode(9,OUTPUT);
//start serial with midi baudrate 31250 or 38400 for debugging
Serial.begin(31250);
}
//loop: wait for serial data, and interpret the message
void loop () {
if (Serial.available() > 0) {
// read the incoming byte:
incomingByte = Serial.read();
// wait for as status-byte, channel 1, note on or off
if (incomingByte== 144){ // note on message starting starting
action=1;
digitalWrite(statusLed,HIGH);
}else if (incomingByte== 128){ // note off message starting
action=0;
digitalWrite(statusLed,LOW);
}else if (incomingByte== 208){ // aftertouch message starting
//not implemented yet
}else if (incomingByte== 160){ // polypressure message starting
//not implemented yet
}else if ( (action==0)&&(note==0) ){ // if we received a "note off", we wait for which note (databyte)
note=incomingByte;
playNote(note, 0);
note=0;
velocity=0;
action=2;
}else if ( (action==1)&&(note==0) ){ // if we received a "note on", we wait for the note (databyte)
note=incomingByte;
}else if ( (action==1)&&(note!=0) ){ // ...and then the velocity
velocity=incomingByte;
playNote(note, velocity);
note=0;
velocity=0;
action=0;
}else{
//nada
}
}
}
void blink(){
digitalWrite(statusLed, HIGH);
delay(1000);
digitalWrite(statusLed, LOW);
delay(1000);
}
void playNote(byte note, byte velocity){
int value=LOW;
if (velocity >10){
value=HIGH;
}else{
value=LOW;
}
//since we don't want to "play" all notes we wait for a note between 36 & 44
if(note>=36 && note<44){
byte myPin=note-34; // to get a pinnumber between 2 and 9
digitalWrite(myPin, value);
}
}
Anyone else seen this?
