MMMC sysex Transport messages

Hello,to all reaper afficionados,
i'm building a system with a 10" screen to control the DAW,using only the buttons created by the TFT,
i've found enough materials to create a sketch for transport control:
Code: 
//---------------------SYSEX COMMANDS REAPER MACKIE CONTROL MMC------------------------
byte sysex_stop[]= {0xF0, 0x7F, 0x7F, 0x06, 0x01, 0xF7};//stop
byte sysex_play[] = {0xF0, 0x7F, 0x7F, 0x06, 0x02, 0xF7};//play
byte sysex_defPlay[] = {0xF0, 0x7F, 0x7F, 0x06, 0x03, 0xF7};//deferred play
byte sysex_fastForward[] = {0xF0, 0x7F, 0x7F, 0x06, 0x04, 0xF7};//fast forward
byte sysex_rewind[] = {0xF0, 0x7F, 0x7F, 0x06, 0x05, 0xF7};//rewind
byte sysex_punchIn[] = {0xF0, 0x7F, 0x7F, 0x06, 0x06, 0xF7};//punch in
byte sysex_punchOut[] = {0xF0, 0x7F, 0x7F, 0x06, 0x07, 0xF7};//punch out
byte sysex_pause[] = {0xF0, 0x7F, 0x7F, 0x06, 0x09, 0xF7};//pause

...and so on
void setup()

...and so on
void loop(){

if(blabla...){
usbMIDI.sendSysEx(sizeof(sysex_stop), sysex_stop, true);
}


}
But i've some problem with the PAUSE,it never stops,only quickly stop then play continuously,the others like
stop,play,rewind,fast forward work fine.
Does someone has the same trouble? :unsure:
 
I didn't notice that i was always repeating the play and sthe stop in a loop because you can't see it,until
you look at the monitor to debug,i should have noticed it with the forward and review never stopping.

Well i've not that problem when i use physical buttons and the pressed/released process,it gives only one reaction,
but with the TFT touch button,it's always in a loop and don't stop after one reaction.

physical buttons exerpt:
Code: 
if (button2.pressed())
{
   usbMIDI.sendSysEx(sizeof(sysex_play), sysex_play, true);
 
   Serial.println("Button 2 PLAY pressed");
 
}

if (button2.released())
{
   Serial.println("Button 2 PLAY released");
 
 
}

The ideal is to simulate a physical button process,but how? :unsure:

EDIT:i use the goodix.h driver for the touch because i'm using a RA8876 TFT
and it's not easy to make it work like adafruit FT6206.

Ok, finally @DJETH helped me to handle goodix's touch in a better way,no more problem with the loop result and touch is fast,

Here's the MMC touch with goodix & RA8876 - 4 wires that works with my reaper DAW.
