Well-known member
I am trying playing waveforms sounds on Teensy4.1 from Teensy LC using Midi communication.
i will connect ( Teensy LC's Gnd to Teensy 4.1's Gnd) & ( Teensy LC's Tx to Teensy 4.1's Rx). to send Midi commands Teensy LC to Teensy4.1.
I upload below code succesfully to Teensy
Code: 
#include <Keypad.h>                           
#include <MIDI.h>

const uint8_t ROWS = 8;  // 8 rows                        For TEENSY  LC as MIDI Keypoard
const uint8_t COLS = 8;  //8 columns   
char keys[ROWS][COLS] = {
{1,2,3,4,5,6,7,8},
{9,10,11,12,13,14,15,16},
{17,18,19,20,21,22,23,24},
{25,26,27,28,29,30,31,32},
{33,34,35,36,37,38,39,40},                 //  8 x 8

{49,50,51,52,53,54,55,56},
{57,58,59,60,61,62,63,64},
};
uint8_t rowPins[ROWS] = { 4,5,6,7,8,9,14,15  };    // 4,5,6,7,8,9,14,15         16,17,18,19,20,21,22,23
uint8_t colPins[COLS] = {16,17,18,19,20,21,22,23 };         
Keypad kpd = Keypad(makeKeymap(keys), rowPins, colPins, ROWS, COLS);

MIDI_CREATE_INSTANCE(HardwareSerial, Serial1, MIDI);
const int channel = 1;



void setup() {
     MIDI.begin();
    kpd.setHoldTime(2000);
    
}

void loop() {

        if (kpd.getKeys()) {
        for (int i = 0; i < LIST_MAX; i++) 
        {    int mykey = (kpd.key[i].kchar);
            if (kpd.key[i].stateChanged)  //  -----------------------------------------Key Changed----------------
            {      switch (kpd.key[i].kstate) {
                    case PRESSED:
                     MIDI.sendNoteOn(40+mykey, 127, 1);
                        break;
                         case RELEASED:
                          MIDI.sendNoteOff(40+mykey, 0, 1);
                        break;
                        
                }
            }  //--------------------------------------------------------------------------------------------------   
             if ((kpd.key[i].stateChanged)  && (mykey ==37))  //  -----------------------------------------Key Changed----------------

how to fix it????
 
@charnjit: I was able to successfully compile your code here (Arduino IDE 1.8.19 + TD1.60b1 & Arduino IDE 2.3.4 + TD 0.60.1), with either "Serial + MIDI" or just "MIDI" selected as the "USB Type" & T4.1 as the "Board:". I did comment out the audio portions of your sketch (assuming that the problem you are looking to resolve is MIDI related, not audio related).

I would suggest that you reload both your IDE & your TeensyDuino, as it is possible that portions are either corrupt, or have been blocked/removed by your anti-virus protection.

Here's the actual code that I compiled, if you want to try it to verify . . .

THANK YOU ,,,
I am using win7 32 Arduino 1.8.19 Teensyduino1.59 .
I was able to successfully compile your code here (Arduino IDE 1.8.19 + TD1.60b1
Click to expand...
I could not see TD 1.60. on
Pjrc page
as i see on error , i seemed it is related to midi.but here i found another way to communicate these 2 boards .
Code: 
#include <SoftwareSerial.h>
i succesfully upload code to both boards
i write in sender board : "101" for Note_On ,,,,, "mykey" for Note ,,,, "100" for Note_Off
Code: 
 {    int mykey = (kpd.key[i].kchar);
            if (kpd.key[i].stateChanged)  //  -----------------------------------------Key Changed----------------
            {      switch (kpd.key[i].kstate) {
                    case PRESSED:
                    mySerial.write(101);
                     mySerial.write(mykey);
                        break;
                         case RELEASED:
                      mySerial.write(100);
                     mySerial.write(mykey);
                        break;
                        
                }
            }  //--------------------------------------------------------------------------------------------------
and trying to read it from Teensy 4.1 . when i use
Code: 
// --------------------------------Read serial-------------------------------------------------------------
 int type, note, velocity, channel, d1, d2;
         if (mySerial.available())
    {

        Serial.println(mySerial.read());
 
      }
    // --------------------------------Read serial------------------------------------------------------------
serial monitor is printing right value
when i use:
Code: 
// --------------------------------Read serial------------------------------------------------------------
 int type, note, velocity, channel, d1, d2;
         if (mySerial.available())
    {
      type = mySerial.read();
      note = mySerial.read();
   if (type==101) {  Serial.println(note);  Serial.println("on"); }
    else  if (type==100) {  Serial.println(note);   Serial.println("off");} 
      }
    // --------------------------------Read serial------------------------------------------------------------

i am getting "-1" for "note" variable. & "on" when type is 101 & "off" when type is 100
where is missing ??
how to assign variable "note" from "mySerial.read()"
