MIDI lib, controlling volume on ch 1 with pot

Using Arduino Audio
7

In the meantime I worked on the remainder of the code. I got pitch bend and reset 0 point to work.

Here's the code in its entirety

#include <MIDI.h>
# define SWITCH 7 // switch for noteOn
# define PITCHADJUST 8 // switch to adjust pitch
# define PITCHINPUT 1 // 10 turn pot for pitch bend

int val1 = 0;
int val2 = 0;
int DATA3 = 0;
int noteCounter = 0;
int MIDI_ROOT_NOTE = 60;

int PITCHADJUST_RANGE = 0;
int PITCH_RANGE = 24;

byte LowerBits;
byte UpperBits;

int SensorPin = 0; // Connect the pressure sensor to A0
int sensorValue;
int MidiValue = 0; // volume Value
int Old_midiValue;
int vol07 = 0;
int vol39 = 0;
int cc7 = 7; 
int cc39 = 39;

float MIDIPITCHSCALE = 0.03785;

MIDI_CREATE_DEFAULT_INSTANCE();

void SendMIDI (char cmd, char data1, char DATA2) {

  Serial.write(byte (cmd));
  Serial.write(byte (data1));
  Serial.write(byte (DATA2));

}

void control () {

  val1 = digitalRead (SWITCH);

  if (val1 == HIGH) {
    noteCounter = noteCounter + 1;
    if (noteCounter == 1) {
      SendMIDI(0x90, MIDI_ROOT_NOTE, 127);
    }
  }
  else {
    SendMIDI(0x80, MIDI_ROOT_NOTE, 127);
    noteCounter = 0;
  }
}

void volume () {
 sensorValue = analogRead (SensorPin);
 MidiValue = sensorValue * (16383 / 1023);
 
 if (MidiValue > 16383){
   MidiValue = 16383;
 }
 if (MidiValue < 0){
   MidiValue = 0;
 }
  
  vol07 = (byte)(MidiValue >> 7);
  vol39 = (byte)(MidiValue & 0x7F);
  
  SendMIDI(0xB0, cc7, vol07);
  SendMIDI(0xB0, cc39, vol39);
  
}



void ProcessAnalogValue (byte) {

  float _x = Z(1);
  val2 = digitalRead(PITCHADJUST);
  if (val2 == HIGH) {
    DATA3 = analogRead(1);
    PITCHADJUST_RANGE = 608 - DATA3;
  }
  int _Converted = (int) ((_x - 297 + PITCHADJUST_RANGE) / MIDIPITCHSCALE);

  if (_Converted > 16383) {
    _Converted = 16383;
  }
  if (_Converted < 0 ) {
    _Converted = 0;
  }

  LowerBits = (byte)(_Converted & 0x7F);
  _Converted >>= 7;
  UpperBits = (byte)(_Converted & 0x7F);

  SendMIDI(0xE0, LowerBits, UpperBits);
}


float Z (byte PIN)
{
  int tmp;
  int data1 = 0;
  int DATA2 = 0;
  int summary = 0; // summary of input data
  int h;

  // Get average data from Analogpin1
  for (h = 0; h < 10; h ++) {
    data1 = analogRead (PITCHINPUT);
    summary = summary + (data1);
  }
  tmp = summary / 10;
  return (float) tmp;
}


void setup() {

  MIDI.begin(1);
  Serial.begin(115200);
  SendMIDI (0xB0, 0x06, PITCH_RANGE);
  pinMode (PITCHADJUST, INPUT);
  pinMode (SWITCH, INPUT);
}

void loop() {

  volume();
  control();
  ProcessAnalogValue(PITCHINPUT);
  delay (1);
}

Credit for the code goes to Mitshusi Abe, I only tinkered with it to get it working.
