Installation

maelzel needs a python version >= 3.9. For all platforms, the installation is the same:

pip install maelzel

There are some external dependencies which need to be installed manually:

Dependencies

MacOS

Install Csound

Download the .dmg package from https://csound.com/download.html (latest release: https://github.com/csound/csound/releases/download/6.18.1/Csound-MacOS-universal-6.18.1.dmg)

Install Lilypond

At the moment the recommended method to install lilypond is via homebrew: brew install lilypond. This will install the last version for your platform (both intel and arm64 architectures are supported) and add it to your PATH. See also: https://formulae.brew.sh/formula/lilypond

Windows

Install Csound

Install csound from https://csound.com/download.html. Use the installer: this will take care of setting up the PATH and setup csound so that it can be found by maelzel

This is currently not needed. Lilyond is installed automatically. These instructions are here only for reference

  1. Download https://gitlab.com/lilypond/lilypond/-/releases/v2.24.1/downloads/lilypond-2.24.1-mingw-x86_64.zip.

  2. Unzip it and place the folder lilypond-2.X.Y in C:\Program Files.

  3. Add the path C:\Program Files\lilypond-2.X.Y\bin to your PATH environmental variable (as “System Variable”)

Linux

Arch

sudo pacman -S csound lilypond

It is possible to install csound via the package manager:

sudo apt-get build-dep csound
sudo apt-get install cmake
git clone -b csound6 https://github.com/csound/csound.git csound
cd csound
mkdir build && cd build
cmake ..
cmake --build . --parallel
sudo cmake --install .
