From MRAC Publishing:
Symbolic Composer is the most advanced and largest music composition language available with over 1000 music algorithms, suitable for modern, dance, classic, electronic, ambient and experimental styles. SCOM generates MIDI files and uses QuickTime Music Instruments for default playback. MIDI application loader can be set to a custom sequencer, MIDI player, or a software synthesis system such as Reaktor for direct playback used by the personal studio defaults.
What's new in this version:
This update fixes bugs and it is suggested for all user. The fixes smooth out work-flow on extensive music making sessions, and provide now also possibility to play sections with simply selecting a string such as "sect-a" in the editor. It also adds store-section, which allows plain non-evaluated section definitions which are later evaluated with redef-section.
