Ability to read DAW output

[Arti5458]

Hi!
I'm creating MIDI controller based on Arduino Mega. I have a couple of encoders and potentiometers. Now, I already can use it with DAWs (particularly, Ableton Live) to control any elements that support control via MIDI, including any plugins (e.g. Portal or Thermal).

The only last thing I need is to read the actual value of this plugin or raw Ablton elements and print it on a small LCD screen. I have no issues with working with the screen. I just need to retrieve the correct values from those elements. Cause, for example, my encoder just sends +1 or -1 to MIDI channel and I don't know the actual value of what I'm changing in Ableton.

So my question - Is there any way to read such values via MIDI output or other protocols?

The one approach I have in my thoughts -

1. Is to create Arduino internal counter with the same limit range as Ableton elements have (e.g. from 0 to 127).
2. Do not allow that counter to go out of this limit range.
3. Increment and decrement this counter when sending the signal to MIDI.
4. And when I increment/decrement the encoder to one side more times than limit range length - I can guarantee that both, Ableton element and my internal counter would have the same value (e.g. 0 or 127).

But this approach has lots of inconveniences, so I'm looking for a way to know the exact value from Ableton.

Thanks in advance to everyone willing to help!

Attaching my Arduino code below.

`
#include <Control_Surface.h> // Include the Control Surface library

#include <LiquidCrystal_I2C.h>

// Instantiate a MIDI over USB interface.
USBMIDI_Interface midi;

LiquidCrystal_I2C lcd(0x27,16,2); // set the LCD address to 0x27 for a 16 chars and 2 line display

CCRotaryEncoder enc1 {
{22, 23}, // pins
{MIDI_CC::Dry_Wet, CHANNEL_10}, // MIDI address (CC number + optional channel)
4, // optional multiplier if the control isn't fast enough
};

CCRotaryEncoder enc2 {
{29, 30}, // pins
{MIDI_CC::Speed, CHANNEL_10}, // MIDI address (CC number + optional channel)
4, // optional multiplier if the control isn't fast enough
};

// Instantiate a CCPotentiometer object
CCPotentiometer Macro1 {
A0, // Analog pin connected to potentiometer
{MIDI_CC::Macro1, CHANNEL_10}, // Midi CC 3
};
CCPotentiometer Macro2 {
A1, // Analog pin connected to potentiometer
{MIDI_CC::Macro2, CHANNEL_10}, // midi CC 9
};

void setup() {
Control_Surface.begin(); // Initialize Control Surface
lcd.init(); // initialize the lcd
lcd.backlight();
// Print a message to the LCD.
lcd.setCursor(3,0);
lcd.print("Hello, world!");
Serial.begin(9600);
}

void loop() {
Control_Surface.loop();
}
