Midi-In Sysex

Hi!

I'm trying to read the sysex messages from a yamaha mixer with my arduino, but i'm doing something wrong for sure.

With the RTMIDI library (c++), it's easy to get a valid message like this one:
F0 43 10 3E 12 01 00 33 00 00 00 01 00 00 00 00 09 F7
(F0 -> begin sysex message, 43 ->Yamaha Vendor ID..... F7 -> End of the Sysex message)

I was expecting to read the same data format from the arduino, but what i get instead is something like:
FC 00 22 or values like those (in 3 Bytes groups)

I'm using a LCD to debug, as the serial monitor will not sync at the 31250 bauds of the Midi rate.

This is a very tiny code just to check the incoming data:

void setup() {
  lcd.begin(16, 2);
  pinMode(2,INPUT);
  digitalWrite(2, HIGH); // My resistor is there

  pinMode(3,OUTPUT); // Pins for other stuff (DIP)
  pinMode(4,OUTPUT);
  pinMode(5,OUTPUT);
  pinMode(6,OUTPUT);
  pinMode(7,OUTPUT);


  Serial.begin(31250);        //midi baudrate
  Serial.flush();
  
  lcd.print("Receiving");
 
}

void loop () {
  
 if (Serial.available() > 0) {
  incomingByte = Serial.read();
        lcd.print(incomingByte, HEX);
                               
          }else{
                lcd.home();

                }

      }

I really don't know if the first data i'm receiving (Not the F0 byte which is what i need), is becouse i'm doing something wrong... but if i'm able to read the midi port, what else can i do?

Thank you in advance!

Hi knob2001. I don't have any solutions for you, but I'm starting a similar project this week. I was wondering if you had a solution to your problem.
