 Welcome to Anthem!

Anthem is an advanced open source MIDI sequencer. Anthem allows you to record, edit and playback music using a sophisticated and acclaimed object oriented song technology. It runs under the KDE desktop environment, on Unix-based platforms.

It is based on the TSE3 sequencer engine and therefore provides a great deal of power, combining the innovative object oriented TSE3 song technology with a simple, intuitive interface.

This open source edition of Anthem is based on a previous commercial version which ran on Acorn RISC OS computers. This open source version of Anthem will only run on Unix-based platforms.

Anthem is still very much a work in progress, so keep coming back to see the latest developments. Anthem is developing fast.

Anthem is a Trax Software product, written by Pete Goodliffe.

  • Powerful linear sequencer
  • Flexible object-oriented song structure
  • Handles import and export of standard MIDI files (both type 0 and 1)
  • Playback with real time effects (remapping, transpose, quantise, velocity window, repeat, offset, etc)
  • GM/GS/XG support
  • Synchro start of playback
  • On screen gadgets, including:
    • Studio clock
    • Virtual keyboard
    • VU bars
    • Go to time
  • MIDI panic facility
  • Any number of tracks per song
  • Highly configurable metronome
  • MIDI echo facility

  • Intuitive user interface
  • Imports Cakewalk instrument definition files

Additional facilities which will be incorporated shortly:

    • Step editor
    • Drum editor
    • Innovative new stave roll editor
    • Score editor

In order to use Anthem to its full potential you will need a soundcard, preferably with external MIDI device support. Anthem will work without such a card, but it will not provide any musical output.

In order to use anthem you will need the KDE 2/3 libraries installed on your system and the TSE3 library. Anthem will produce MIDI output on any system that TSE3 supports - see the library pages for more information.

There are more details on the download page.
