Ok, It's bedtime here and this code compiles so am looking forward to good news.

Code:
///************LIBRARIES USED**************
#include <MIDI.h>
MIDI_CREATE_INSTANCE(HardwareSerial, Serial1, MIDI);
#include <ResponsiveAnalogRead.h>

// ******CONSTANT VALUES******** 
const int channel = 1; // MIDI Out channel
const int A_PINS = 1; // number of Analog PINS

// define the pins you want to use and the CC ID numbers on which to send them..
const int ANALOG_PINS[A_PINS] = {A0}; //            Need to change this 
const int CCID[A_PINS] = {16};  //CC for Modulation. Need to change this

//******VARIABLES***********
// a data array and a lagged copy to tell when MIDI changes are required
byte data[A_PINS];
byte dataLag[A_PINS]; // when lag and new are not the same then update MIDI CC value

//************INITIALIZE LIBRARY OBJECTS**************
ResponsiveAnalogRead analog[]{{ANALOG_PINS[0],true}}; 

int previousTimer;

//************SETUP**************
void setup() {
  MIDI.begin(MIDI_CHANNEL_OMNI); 
}

//************LOOP**************
void loop() {
    MIDI.read();
    mergeIncoming();
    getAnalogData();
    doActiveSensing();
}
//*************Merge
void mergeIncoming()
        {
   if (MIDI.read())
            {
        MIDI.send(MIDI.getType(),MIDI.getData1(),MIDI.getData2(),MIDI.getChannel());
            }
        }
//************ANALOG SECTION**************
void getAnalogData(){  
  for (int i=0;i<A_PINS;i++){
    // update the ResponsiveAnalogRead object every loop
    analog[i].update(); 
    // if the repsonsive value has change, print out 'changed'
    if(analog[i].hasChanged()) {
      data[i] = analog[i].getValue()>>3;
      if (data[i] != dataLag[i]){
        dataLag[i] = data[i];
        MIDI.sendControlChange(CCID[i], data[i], channel);
      }
    }
  } 
}  
//******** Send Active sensing
void doActiveSensing()
     {
   int currentTimer = millis();
      if(currentTimer - previousTimer > 300)// If 300Ms has passed
        {
          // Reset the counter
          previousTimer = currentTimer;
          // And send ActiveSensing
          MIDI.sendRealTime(0xFE);
          // and you need to find and put the number for activeSensing inside the brackets.
        }
      }
