Redwood City, Calif.-based U&I Software on Monday released MetaSynth 4 and MetaSynth 4 Pro, new versions of the company’s sound design tool. The developer noted so much has changed that it decided to bypass version 3 when updating version 2.7, the last one released. In addition to a revamped user interface, the software offers such new real-time capabilities as real-time stereo previews and capture-to-disk, along with the ability to create and play music on the fly in the Image Synth and Effects “rooms.”


Metasynthesis Of Qualitative Studies

MetaSynth, two-time recipient of Electronic Musician's prestigious Editor's Choice Award, is an extraordinary new visual paradigm for music composition, sound synthesis and sound design that applies the power of advanced image processing techniques to a sophisticated audio rendering engine. MetaSynth’s other windows fall into two categories: windows for creating source sounds to be used in synthesiz-ing pictures and windows for sample processing. But since any sample can be used as a source for synthesizing pic-tures, these categories overlap.

MetaSynth 4 features six “rooms” — Effects, Image Synth, Image Filter, Spectrum Synth, Sequencer and Montage — that offer different ways to create and manipulate music. Image Synth now supports layers and includes a built-in graphic equalizer. In the Effects room, users can employ envelope control of effects parameters and new effects while taking advantage of improved fidelity.


Four of the rooms are new: Image Filter, in which users can create dynamic stereo filters with MetaSynth’s image-to-sound capability; Spectrum Synth, which uses granular spectral synthesis for creating music by analyzing, editing and rearranging the harmonics of other sounds; Sequencer, a non-MIDI single-track sequencer with single- and multi-oscillator instruments; and Montage, which replaces the previous MetaTrack utility and offers 16-track mixing. Ultranium 4.

The regular version of MetaSynth 4 opens and saves sounds in 16-bit format while Pro employs 24-bit format and includes a recording feature in the Montage room. U&I Software said that current MetaSynth users should receive an email regarding discounted upgrades from previous versions; check the product page for more information if you didn’t receive one. The regular version of the software is US$499 while the Pro edition is $599. System requirements were not provided.

Metasynth Alternative

'An electronic music studio for Mac where you create, compose, design and transform music and sound in a unique environment that invites exploration.'

This app was used by Aphex Twin to insert his face into the frequency spectrum of his music, and repeatedly used in The Matrix to give the movie its extremely clean and distinct timbre for anything that had to sound digital.

Download #1 contains MetaSynth 2.7.1 and 2.7.2b. The 2.7.x versions are the latest for the original Mac OS.
Download #2 contains MetaSynth 2.6.1 with many extra goodies.
Download #3 contains MetaSynth 2.6.1 with content different from the previous download.
Download #4 contains MetaSynth 2.5.
Download #5 contains MetaSynth 2.0.
Download #6 contains a patch file that cracks some unspecified version(s) of MetaSynth for the original Mac OS.

The next version of MetaSynth, MetaSynth 4.0, was for Mac OS X only. (There never was a 'version 3'.)

As of 2019, MetaSynth continues to be developed as a 32-bit Mac OS X app for Mac OS X 10.6 through 10.14, with a 64-bit version planned in 2020.
