Mezzz + vidOS Mega Guide for Firmware 1.4: Audio Reactivity, Presets, and More!

Hey Sleepyheads!

We are back with an updated Mezzz and vidOS user guide for the firmware 1.4.

This video reviews the new features added to our flagship portable video system since the last tutorial. It demonstrates using the Mezzz MIDI controller and the generative 3D video app, vidOS, to make rad visuals for live performance! This video guide covers the Mezzz hardware, making shapes, navigating pages, using internal modulation, setting up audio reactivity, presets, and recording your work.

If you want to learn even more, be sure to check the online manual and guides at… and the first Mega Tutorial here: • Mezzz + vidOS Mega Demo!

Hey Ron .
An amazing update , and for the first time vidOS is working on my Mac desktop . Although it did crash in the first 5 mins … would like the crash reports sent to you ?
Also this version runs so slow on my iPad Pro … what spec iPad is needed for it run smooth ?
Or are there any tweaks … I’ve tried lowering the bit rate in the settings this seems to have a posaitive effect . However , I’d like to be able to use the sound envelope follower and this is way to slow to seem like it’s working on my iPad Pro … 3rd generation running iOS 17.5.1 …
Any ideas ? Thanks

Have you tried using the resolution scaling in the settings menu? thats the primary way to optimize for older devices. Honestly the newer the device the better since this type of synthesis (essentially simulating rays of light) takes a lot of processing power and wasn’t even really viable for realtime use until recent leaps with chip performance.

The crash reports come to me through the app store if you submit them. What where you trying to do when you experienced the crash?

not sure what you mean by lowering the bitrate, bitrate of what?

Hi Ron
What I meant was by lowering bitrate , was lowering the resolution as you suggested … yes it does perform better , but then it looks so lo FI .
I like the shiner hi FI …
is there a way to use an older version of vidOS ? Can I roll back …
I literal spend £500 on this pad as soon as I got mezz , as mezz wouldn’t work on my older one …
so now I need to spend 700 on one that might be capable of running vidOS seemlessly ?
So I buy a device that’s cost £350 and then need to spend two times that much to use as intended … hmm
Now I know what it feels like to be a teenager buying my first car …
you can get a decent car for 500 quid , but you can’t use it unless you can afford 1200 insurance …
im a bit baffled how such updates have caused so much more processing , I was not even doing anything heavy … literally expanding the size to see the shape has measurable latensey . Where as before it was fine …

Hey there, the same could be said for running resolume or touch designer on a shit computer with integrated graphics, It works, but not near as well as on an optimized device with a dedicated graphics card.

Though while I’m not too familiar iPad’s and more contemporary Apple Silicon devices just yet, these newer M2 series or higher are going to be the way forward for more graphics-intensive applications, vidOS included.

I’ve got iPhone 13 Pro here that runs vidOS quite alright and an iPad 6 that runs vidOS not-so-great. But the M2 iPad vidOS was running on at Superbooth was running miles beyond either.

It’s still a bit uncharted territory, but the newer, with Silicon-based chips, the better when it comes to vidOS and Touch Designer-like video software.

How about the smoothing setting have you tried that? This one will add a slew to all the controls for smoother transition so if its far up this will add some deliberate transition time.

The performance requirement didn’t rly change from the last version as far as i am aware…

I develop the engine on M1 so it should be ok there. The performance overall fluctuates up and down as I add new stuff then proceed to learn to optimize it over time and thats to be expected. vidOS will be targeting M1+ moving forward the whole point is that the tech just now makes this type of realtime ray marching possible and to utilize the modern hardware that can improve without coupling to the Mezzz hardware.

Bravo on this update, modulation levels and audio reactivity are extremely welcome!
