Midi controller, LED status with push buttons

Other Hardware LEDs and Multiplexing
1

Hello, I have built a midi controller set up like this

it has modes of record, play and also overdub. I plan to use it in ableton live with mobius. The circuit I have built has a led to show if the pedal is in record mode or play mode

Record mode HIGH
play mode LOW

my code at the moment is: Dropbox - File Deleted

I want a led above track 1, 2, 3 and 4 to show the status of each track, I'm using common cathode 4 leg leds (without wiring the blue as I don't need it)

So I need the led to light up green when the track is playing and light up red when recording and possibly light up red also when overdubbing. each pedal is sending a midi note when pressed. I don't know if this is possible or not? it just gets complicated trying to keep track at what state the controller is at and also each track

any help would be great because I don't know where to even start with this. Here are the notes for each button. first notes on and off are in play mode and the second notes on and off are in record mode

Record Button

I don't know if this is possible or not?

Yes it is.

There has been a few such projects, this is one of them Recording Lights are looking for advice || help - Audio - Arduino Forum

This is the code from the link, is this what I need?

byte incomingByte;
byte noteByte;
byte velocityByte;
byte noteOn=0x90;

void setup(){
Serial.begin(38400);
pinMode(12,OUTPUT);
}

void loop()
{
if(Serial.available () > 2){
incomingByte = Serial.read();
noteByte = Serial.read();
velocityByte = Serial.read();
if (incomingByte == noteOn & noteByte == 95 & velocityByte ==127){
digitalWrite(12,HIGH);
}
else if (incomingByte == noteOn & noteByte == 93 & velocityByte ==127){
digitalWrite(12,LOW);
}
}
}

is this what I need?

No. Read that code, you need to change what it responds to, into what your system sends.

any help would be great because I don't know where to even start with this.

This is help, it is where to start, like you asked for.
If you want someone to write the code for you then post in the Gigs and Collaboration section and say what you are prepared to pay.
