DESCRIPTION

Beast is a digital synthesizer and music creation system. It has support for Linux Audio Plugins (LADSPA), multi-track editing, unlimited undo, real-time synthesis, MIDI and various free audio codecs. Bse is the Beast Sound Engine, a library providing the synthesis and audio functions used by Beast.

REQUIREMENTS

Beast is a soft realtime application which needs elevated CPU scheduling priorities to avoid audio glitches and drop outs. For this purpose, it installs a small uid wrapper which acquires nice level -20 for the synthesis threads and then immediately drops privileges. For Linux kernels of the 2.6.x series and later, this enables the low-latency scheduling behavior needed to avoid audio artefacts.

In order to build release tarballs, Rapicorn, GnomeCanvas, Ogg/Vorbis, libflac and npm are required. Support for MP3 files is optional and requires libmad (MPEG audio decoder library) when compiling Beast. Compilation requires g++-5.2.1 or later and a recent Linux distribution like Ubuntu-14.04.

INSTALLATION

In short, Beast needs to be built and installed with:

./configure
make
make check         # run simple unit tests
make install
make installcheck  # run audio tests

Note that Beast has to be fully installed to function properly, and that the binaries built in the launchers/ directory have to be installed with permissions of the root user.

BINARY PACKAGES

New source code pushed to the Beast repository is automatically built and tested via Travis-CI. Ever so often we create release candidate packages and later release packages after a stabilization phase. Some of the release candidates and the stable versions are provided as binary packages which can be installed via apt:

# Enable HTTPS transports for apt
apt-get -y install apt-transport-https ca-certificates wget
# Recognize signatures from the Beast-Team
wget -qO- https://beast.testbit.org/apt/archive.key | sudo apt-key add -
# Add Beast release packages to the repository list
echo "deb https://beast.testbit.org/apt xenial/stable/" |
  sudo tee -a /etc/apt/sources.list.d/beast-team.list
# Update package list and install Beast
apt-get update && apt-get -y install beast

The directory xenial/stable/ holds end user release packages, and the directory xenial/rc/ holds temporary release candidates.
