Command line tool for Mac and Linux for exporting Rosegarden files to MIDI files.

The code in this repository is adapted from the Rosegarden project:

https://www.rosegardenmusic.com/

Rg-2-midi was created by lifting out the minimal subset of code files from Rosegarden that were needed to support the reading of .rg files and the exporting of MIDI files, then gluing them to together with a small bit of code in main.cpp. Additionally, certain sections of code were commented out to remove dependencies not necessary for the task at hand, though nothing was added.

The Rosegarden project is an open-source GPLv2-licensed project, hence this project is also GPLv2, including the new code added to it that was not taken from Rosegarden.

$ rg2midi /path/to/sample.rg /path/three/sample.mid

First ensure that you have basic C/C++ compiler tools installed on your system (sudo apt install build-essential should do that for you on a Linux apt-based system such as Ubuntu, Debian, Mint, etc.). On Mac you would need to install X-Code. You will also need CMake installed. If that is not installed then install it via your package manager (should work on either Linux or Mac). Then make sure that you have have the following dependencies:

1. Qt5 Core
2. Qt5 Xml
3. zlib

On Linux you can find these in your package manager and on Mac you could use e.g. sudo port install qt5 (that is what the author does). Once you have that, then:

$ git clone https://github.com/dpacbach/rg-2-midi rg-2-midi
$ cd rg-2-midi
$ mkdir build
$ cd build
$ cmake .. -DCMAKE_BUILD_TYPE=Release
$ make -j4

Then you will find the binary in build/src/rg2midi which you can then copy to wherever you like, though keep in mind that it will need the relevant Qt5 and zlib libraries present in standard locations on the system in order to run.
