What's New in Mozaic Plugin Workshop

Small fix: filenames are now remembered across sessions when saving/opening files

User reviews

Powerful concept and useful, but still has few kinks that needs to be fixed

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!

Still the King of Midi Mangling

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).

ABSOLUTELY OUTSTANDING

I purchased this app to enable me to receive and send SysEx data dumps from my keyboard to Cubasis3 on my iPad, mainly to change the transpose to what ever key I require, but just by selecting one of many templates in Mozaic I was able to achieve my goals without any effort on my part. Best purchase ever in my opinion.
Worthy of 10 stars ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️

Essential

Essential for ios midi affairs.. also great manual that lays bare midi's inner workings

Absolutely incredible!

I started out using this app to make my old Novation LaunchControl Mk1 light up the pads when i pressed them, and as I got to grips with the incredible Mozaic programming language I came to realise the vast possibilities I suddenly had at my fingertips. This has turned my simple hardware and ipad combination into something that can do exactly what i want it to do, no need to search for other apps that can sort of get me close to what I want. Incredible.
