Volume Control Voicemeeter C#

This project is based on deej and the Voicemeeter API. It enables you to control Voicemeeter with analog Arduino Input

Installation

1.Use the Arduino IDE to upload this code to the Arduino.

const int NUM_SLIDERS = 11; //Edit based on the sliders you have.
const int analogInputs[NUM_SLIDERS] = {A0, A1, A2, A3, A4, A5, A6, A7, A8, A9, A10}; //Edit based on the sliders you have.

int analogSliderValues[NUM_SLIDERS];

void setup() { 
  for (int i = 0; i < NUM_SLIDERS; i++) {
    pinMode(analogInputs[i], INPUT);
  }

  Serial.begin(9600);
}

void loop() {
  updateSliderValues();
  sendSliderValues(); // Actually send data (all the time)
  // printSliderValues(); // For debug
  delay(10);
}

void updateSliderValues() {
  for (int i = 0; i < NUM_SLIDERS; i++) {
    float AverageTemperature = 0;
    int MeasurementsToAverage = 16;
    for(int r = 0; r < MeasurementsToAverage; ++r)
    {
      AverageTemperature += analogRead(analogInputs[i]);
      delay(1);
    }
    AverageTemperature /= MeasurementsToAverage;
    analogSliderValues[i] = AverageTemperature;
  }
}

void sendSliderValues() {
  String builtString = String("");

  for (int i = 0; i < NUM_SLIDERS; i++) {
    builtString += String((int)analogSliderValues[i]);

    if (i < NUM_SLIDERS - 1) {
      builtString += String("|");
    }
  }
  
  Serial.println(builtString);
}

void printSliderValues() {
  for (int i = 0; i < NUM_SLIDERS; i++) {
    String printedString = String("Slider #") + String(i + 1) + String(": ") + String(analogSliderValues[i]) + String(" mV");
    Serial.write(printedString.c_str());

    if (i < NUM_SLIDERS - 1) {
      Serial.write(" | ");
    } else {
      Serial.write("\n");
    }
  }
}

2. Download Autohotkey and run this script or use the pre compiled Version.

#NoEnv  ; Recommended for performance and compatibility with future AutoHotkey releases.
; #Warn  ; Enable warnings to assist with detecting common errors.
SendMode Input  ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir %A_ScriptDir%  ; Ensures a consistent starting directory.
Run, VoicemeeterSliderControl.exe , , Hide


#z::
Process, Close, VoicemeeterSliderControl.exe

#u::
Run, VoicemeeterSliderControl.exe , , Hide

3. Put the AHK script in the same folder as the VoicemeeterSliderControl.exe file.
4. Edit the Config.json to fit your needs!

{
    "PortName":"COM3",
    "BaudRate":9600,
    "SliderSets":[
    {
        "Slider":0,
        "VoicemeeterValue":"Bus[0].Gain"
    },
    {
        "Slider":1,
        "VoicemeeterValue":"Bus[1].Gain"
    },
    {
        "Slider":2,
        "VoicemeeterValue":"Bus[2].Gain"
    },
    {
        "Slider":3,
        "VoicemeeterValue":"Strip[5].Gain"
    },
    {
        "Slider":4,
        "VoicemeeterValue":"Strip[6].Gain"
    },
    {
        "Slider":5,
        "VoicemeeterValue":"Strip[7].Gain"
    }
    ]
}

5. Run it! When you run it, it starts automatically! (With Win+z and Win+u you can start or stop it.)
