This project is a C++ application that allows you to control your Windows system volume using a MIDI controller. By rotating a MIDI knob, the application reads the MIDI signal and adjusts the system's master volume accordingly.
- MIDI Input: Listens for changes in the MIDI Control Change (CC) value from a MIDI controller.
- Volume Control: Maps the MIDI controller's knob position to the Windows system volume, allowing smooth adjustments from 0% to 100%.
- Error Handling: Catches and displays errors related to MIDI input using
RtMidi.
- Windows: This application is designed for Windows.
- C++ Compiler: A C++ compiler that supports C++11 or later.
- Libraries:
- RtMidi for MIDI input handling.
- Windows API for system volume control.
- mmdevapi.lib: Ensure you link against this library for multimedia device control.
- Clone this repository:
git clone https://github.com/telnorp/midivolcontrol.git
- Find your MIDI port:
- change ccNumber in volumeController.cpp to the number you get in the debug section at https://midi.tools/
- Add preprocessor definition:
- add WINDOWS_MM to preprocessor definitions before compiling. (the code only works on windows platforms on its own)
