Releasing Symbolic Composer 7.2
Download SCOM 7.2.1 here!
2015, AUG 20 --- Tonality Systems today release Symbolic Composer 7.2 for the Mac. This release adds stability though OS X 10.6 up to the latest 10.10.5.

It also adds compatibility with 30 year old scores made on IBM 360/InterLisp 1.5 and Atari from SCOM 0.9 and up. As a commitment to your musical future, SCOM provides a solid platform to experimental composers world-wide.

This release also adds support for latest Sibelius, Logic, Reaper and Renoise apps. It provides up to 30% more speed and provides new functions for the advanced composer. Included are transpose & ornament chains, random chords, tonality belong-filtering, and easy section inversions and reversions.

What is Symbolic Composer?

Symbolic Composer s a massive collection of computer music algorithms packed in an efficient music composition language and interactive development environment.

Besides providing the composer a toolbox of traditional composition tools Symbolic Composer also enables the composer to explore advanced  mathematics to determine compositional elements.

Symbolic Composer's rich molecular music language enables the composer to extend musical capabilities and helps to realize the maximum power of existing studio investments spent on synthesizers and sequencers.

Sounds cool, but does it suit for mortals?

Yes. You are not required to know how to program. Press Listen button to listen computer-generated functions. When you learn a couple of tricks you can program it to produce music the way you want.

Press Listen to preview algorithms. Program a section for details. Make more sections, and then chain them together. Bounce the score to disk and publish.

SCOM works together with Logic, Sibelius, Finale, Encore, MainStage, Digital Performer, Reason, Reactor, Rondo, QuickTime, Renoise, Reaper. Here showing a custom SCOM playback rig in Apple's MainStage.

Control playback with a click, press forward, rewind, stop/continue. Let it loop a section to set up your synth sounds.

Display instant notation, too. Finish them in Sibelius or use free LilyPond. Display generated notation instantly to performers, too.

SCOM Rocks: Introducing Guitar-Synth

If you are into string instruments this special feature is tailored to you.

Tune up guitar, bass or orchestral strings the way you prefer. Then enter tablatures of playing, and turn them into SCOM pieces.

Make riffs and arrange them into full-blown composition. Tweak it algorithmically.

This is also for a guitarist wanting to do some more in digital domain. Or port your skills into modern algorithms.

SCOM The Music Language

• Music Language, that allows composing music of any style and complexity.

• Standard MIDI file output. This makes SCOM a perfect partner no matter of the software and hardware you are working with.

• Build-in 96 channel MIDI playback. Plays through GM MIDI or IAC for final sounds. Press button to record sthe core in production quality audio.

• Build-in Notation (LilyPond), HyperHelp & Search.

• Complete Chord, Scale and Micro-Tonal libraries fully expandable by the user.

• Mathematical Generators & Processors provide advanced fractals, chaos and number-theory functions.

• Symbolic Generators & Processors allow Recursion, L-systems, Fibonacci, and other special solutions.

• Programmable Neurons supply added intelligence to your instrumentation.

• Programmable Phrase Library allows sequential drum and chording pattern generation.

• Historical & Contemporary Music functions supply the classic compositional tools.

• Over 1000 Algorithms included, combine freely to each other for exponential creative freedom.

"SCOM covers past 500 years of compositional traditions and the tools for the future. SCOM's rich music programming language supplies the composer tools to program any music style and complexity. When the idea hits you, just draft your score and press Compile", summarizes composer and music educator Nigel Morgan from UK.

System Requirements
Macintosh OS X 10.6-10.11,  2 GB RAM minimum, 4-32 GB suggested.
Windows XP/7/8, 2 GB RAM minimum, 4-16 GB suggested.


SCOM runs first on Demo Mode, which allows to try out functions. Authorization restores full functionality.



“Symbolic Composer was one of the first systems that I encountered that explored the art of algorithmic composing interactively. The system functions are selected from hierarchical menus and pasted on the editor, so it’s a completely different approach to musical compositions. It’s like composing music from one’s DNA structure.”, Composer Richard Devine.


"Nowadays, symmetries are widely used in musical composition, for instance in the various transformation tools of sequencers, and explicitly in the author‚s prestor (see chapter 49) and in Opcode‚s MAX or in music software with fractal composition tools as realized by Mesias Maiguashca [220] or by the ingenious Symbolic Composer software",  Mazzola G., Author of Topos Of Music (If the direct link has changed due publisher, search the title at Springeronline


"I wish to thanks people that have contributed in important way to the creation of this book:
   All the developers of the wonderful algorithmic composition software Symbolic Composer, that I have used for the composition of the exercises - and Douglas R. Hofstadter for the beauty of his ideas on the perception, and parallels to artificial intelligence", Claudio Martini, Author Of I Pattern Automutanti
