MetaSynth + Xx

Unique Applications for Artists and Musicians

Newsflash: MetaSynth CTX 1.0 for Cocoa MacOS is on it’s way!

Eric is currently re-creating MetaSynth for Apple’s Cocoa Platform (MacOS 11.0, 10.15, and backward compatible to MacOS 10.10). He is working to have it done, tested, and released in Winter 2020/1. Watch for updates in the MetaSynth Users Group.

Xx CTX 1.0 (MIDI for MetaSynth) will follow after that. Support the development of MetaSynth CTX 1.0 by purchasing a PreRelease coupon:

Note: MetaSynth 6.x (Carbon MacOS) owners will be emailed Loyalty 35% off coupons on the day of release (MetaSynth 5.x. 25%). Thank you for your support as we change Apple platforms and ensure this unique product is available for years to come. MetaSynth CTX 1.0 is not an upgrade of the discontinued MetaSynth 1.0 – 6.0 for Apple’s Carbon platform, but a new application for Apple’s Cocoa platform. See more details on the support page.

is an award-winning electronic music and sound design studio for OS X that has created audio for films such as The Matrix, Hannibal, Run Lola Run, Dante 01, Death Race, An Mil… and can be heard on music by Aphex Twin, Junkie XL, Die Form, Audio Terrorist, El Silencio Blanco, Zoreh, and many many more.

Its seven tools allow you to process sounds, and sequence compositions in unique ways. Some of its tools are focused on generating loops and samples (Effects Room and Image Filter), and others on creating sequences for composition (Sequencer and Xx). Sometimes the lines between what is an instrument and what is a sequencer can blur as with the Image Synth which can also be a sequencer! Xx lets you compose with MIDI then export MetaSynth images to put it all together in the Montage room.

Image Synth

Image Synth is our paradigm-smashing composition environment where you paint to sound. It has a host of available synthesis methods with nearly infinite customizable microtonality, the Image Synth makes possible the sounds of your dreams. Also, it can be a sampler or a sequencer!

Image Filter

The filtering counterpart of the Image Synth. Precise dynamic stereo filters that can create a limitless range of effects from the conventional to the otherworldly.

Spectrum Synth

The Spectrum Synth analyzes sounds and creates events that capture the original’s harmonics which you can manipulate, filter, and re-arrange to invent new sounds.

Effects Room

The effects room provides a new approach to sound effects. Both traditional effects like delay, reverb and chorus, can be found here, and a wealth of unusual effects like our granular synthesis-based Grain and Shuffler. The unique graphic envelopes make it easy to turn “standard effects” into something unique.


This is a lightweight non-MIDI sequencer where you can compose musical phrases and rhythm loops that you can render to disk, import into the Image Synth, or add to your Montage Room compositions. Sequencer Room Example Montage Room. 24-track mixing environment. Use this room to mix down full-length compositions or to layer and composite the sounds you create in the other rooms.

Xx (separate application)

Xx is used as a stand alone MIDI sequencer and compositional tool. MetaSynth can be its sound engine, or any softsynth or hardware synth. It can import MetaSynth Sequences and convert then to MIDI, or export MIDI to Montage images for MetaSynth.

Montage Room

Use the Montage Room to quickly assemble MetaSynth-created components.

Legacy MetaSynth + Xx for Carbon MacOS

MetaSynth 6 + Xx 5.5 are discontinued legacy “Carbon” MacOS programs and will run on 10.6 through 10.14. Apple discontinued the Carbon platform after MacOS 10.14. 10.15 is “Cocoa” only. To run Carbon apps under Catalina, you need to create a Dual Boot MacOS system using Apple’s Boot Camp, or a third party product like Parallels or VMware. To download a copy of 10.14 (Mojave) we recommend this tool. These products remain for sale to users who do not plan to upgrade MacOS to a Cocoa only version. Demos, Tutorials, and more can be found at the links below.
