Installation

Download mixer.zip -> Unzip it -> Enjoy

It may be necessary to install CH340 drivers.

Configuration

Before using The Mixer, you need to configure it with the following parameters in the config.yaml file:

• "port": Choose the COM port to which your Arduino is connected.

• "port: auto": Program automatically selects port. Might not work with more than 1 arduino connected to the computer

• "baud-rate": Set the baud rate to match the configuration on your Arduino.

• "apps": Enter the names of the programs you want to control with the potentiometers. You can organize applications into groups to manage audio settings efficiently. You can have multiple groups, and one potentiometer controls the entire group or the programs within that group.

  • Master: Adjusts the overall system volume.

  • Groups: Control volumes of specific groups of applications.

  • Individual Applications: Adjust volumes for specific applications.

  • Ensure that the number of programs and groups listed in apps does not exceed the number of available potentiometers connected to your Arduino. Having more entries in apps than available potentiometers may lead to error.

  Example

  port: Com6
  baud-rate: 9600
  apps:
      - master
      - spotify.exe
      - game:
            - geometrydash.exe
            - terraria.exe
            - rustclient.exe
            - fortnite.exe
      - discord.exe
      - group:
            - opera.exe
            - chrome.exe

  Different example

  port: auto
  baud-rate: 9600
  apps:
      - master
      - opera.exe
      - discord.exe
      - group:
            - spotify.exe
            - AMPLibraryAgent.exe
      - game:
            - geometrydash.exe
            - albion-online.exe
            - rustclient.exe
            - FortniteClient-Win64-Shipping.exe
            - cs2.exe

Arduino Configuration

1. Configure the arduino_code.ino according to your needs:

   • Set the number of potentiometers by changing const int NUM_SLIDERS = X;, where X is the desired number.

   • Define the potentiometers' pins using the const int analogInputs array.

   Example

   const int NUM_SLIDERS = 5;
   const int analogInputs[NUM_SLIDERS] = {A0, A1, A2, A3, A4};
   

2. Upload the modified code to your Arduino.

Usage

1. Connect your Arduino to your computer and ensure it has been programmed with the appropriate code as described in the "Arduino Configuration" section.

2. Run the mixer.exe. If the program doesn't work, check config.yaml. You can do this by clicking Change config in The Mixer options. If you change config make sure that you reload program by clicking reload in The Mixer options.

3. Use the potentiometers connected to your Arduino to control the volume of the specified programs and groups.

All option are in the system tray icon options.

Features

The Mixer provides additional features:

• Running in the Background: The main script runs silently in the background. You can access it through the system tray (hidden icons) on your taskbar.

• Open Config: Right-click on the system tray icon and select "Open Config" to open and edit config.yaml.

• Reload Configuration: Right-click on the system tray icon and select "Reload" to refresh the configuration.

• Exit: To close the program entirely, right-click on the system tray icon and select "Exit."

Autostart with Windows

If you want The Mixer to start automatically with Windows, you can add a shortcut to the program in the startup folder. Here's how:

1. Press Win + R to open the Run dialog.
2. Type %appdata%\Microsoft\Windows\Start Menu\Programs\Startup and press Enter.
3. Copy the shortcut of Mixer.exe into this folder.

Now, The Mixer will launch automatically when you start your computer.

Note

Ensure you have the required hardware set up, including the potentiometers and Arduino, for APVC to work effectively.
