Roll Your Own MIDI Plugins

Overview

Version:

1.4.2

Last updated: 2025-07-10

Features & Capabilities

Create your own MIDI plugins: MIDI filters, generative music tools, basic sequencers, MIDI control panels, chaos experiments... Let your imagination take you places.

Mozaic runs inside your favorite AU MIDI host, and gives you practical building blocks such as LFOs, pre-fab GUI layouts, musical scales, AUv3 support (with AU Parameters, transport events, tempo syncing, etc.), random generators and a super-simple yet powerful script language. Mozaic even offers quick access to your device’s Tilt Sensors for expressive interaction concepts!

The Mozaic Script language is designed from the ground up to be the easiest and most flexible MIDI language on iOS. A language by creatives, for creatives. You’ll only need to write a few lines of script to achieve impressive things - or to create that uber-specific thing that was missing from your MIDI setup.

Check out the Programming Manual on Ruismaker.com to learn about the script language and to get inspiration for awesome scripts of your own.

Mozaic comes with a sizable collection of tutorials and pre-made scripts which you can use out of the box, or which can be a starting point for your own plugin adventures.

Features in a nutshell:

Easy to learn Mozaic Script language: easy to learn, easy to read
Sample-accurate-everything: the tightest MIDI timing possible
Built-in script editor with code-completion, syntax hints, etc.
5 immediately usable GUI layouts, with knobs, sliders, pads, etc.
In-depth, helpful programming manual available on Ruismaker.com
Easy access to LFOs, scales, MIDI I/O, AU parameters, timers
Supports Sysex, with built-in checksum calculations
AUv3; so you'll get multi-instance, state-saving, tempo sync and resource efficiency out of the box

Mozaic opens up the world of creative MIDI plugins to anyone willing to put in a few hours and a hot beverage or two.

Practical notes:

Mozaic requires a plugin host with support for AUv3 MIDI plugins (AUM, ApeMatrix, Cubasis, Auria, Audiobus 3, etc.)
The standalone mode of Mozaic lets you edit, test and export projects, but for MIDI connections you need to run it inside an AUv3 MIDI host
MIDI is not sound; Mozaic on its own does not make noise... so bring your own synths, drum machines and other instruments!
AUv3 MIDI requires iOS11 or higher

User Reviews

Love the concept — a scriptable AUv3 MIDI plugin is brilliant for custom iOS rigs. But the scripting language is surprisingly fragile. Even with AI assistance, simple scripts took multiple rounds to get right due to inconsistent syntax and poor documentation. Two requests: add a clear button for the Log console, and append logs to the bottom, not the top. Enormous potential — please keep polishing it!

I mostly buy music apps use them 2-3 times and then abandon them until out of nowhere both the necessity and remembrance of such tools comes synchronously. Mozaic however, has literally been a plug-in I have tons of instances of ON ANY project. Whilst not the most trivial app, requiring the user to code… after little over a month or two I was making plugs you just can’t find anywhere in the AppStore. I use mozaic for everything, literally has made multiple useless controllers into usable gear (midi stuff obviously) and that doesn’t even account for all the procedural music you can generate (or accompany) with the use of such a versatile tool. Whilst I completely understand why Bram hadn’t made Mozaic 2 (probably not a big seller in comparison to his other amazing apps), I still wish everyday such tool will eventually bless us (perhaps with a modular interface that allows us to build the UI, a la “loopy pro”). My favorite app by Bram, and it hurts to say so cause every single one is amazing (but this one is a game changer for real).
