Rendering Issue in 8.4.18

[Bady89]

Hello Friends,

i try to render my newest Project into a .wav file and i have a problem to get a clean result.

It´s strange, when i render 10 Times the same project i get 10 different results , some times an automation is missing , sometimes some samples.

Pretty strange.

Did anyone faced the same issue ?

Should i upgrade ?

Please render one of the demo projects a couple of times.
Does the same issue occur?

Should i upgrade ?

Of course!
It's always best to update to the latest version.
Currently you can best upgrade to M8.6.26 which is here: http://www.mutools.com/mulab/beta/
It's a beta, but a good one.

Hello Jo,

yes the issue is reproducible and appears in 8 from 10 Renders

The Issue appeared in 4 times on the same Position.

The other 4 times on other positions.

I have some Exampels for you, listen to the rising cutoff in the Bassline.
You can hear it very drastic in Render 11

Render 11 is a full track while the others are 15 sec clips. Is that intended? It makes comparison too hard.

Also these questions:
Does the problem occur with a VST plugin?
If yes then replace that VST plugin by a similar MUX patch and update the automation accordingly.
Does the problem still occur?
In other words: Is the problem related to that VST plugin?

Also this: Please load the first demo project "AirTime".
Render it 3 times. Do all renders sound the same?

Indeed, my mistake.

I corrected and reuploaded it, please check again.

To your question, yes it control the Filtercutoff in the Air Hybrid 3 Plugin

Ill try with stock project tomorrow.

The 3x Airtime Renders sound clean to me.

Guess you want to say it´s an Plugin issue, can´t imagine that for a Common Plugin like the hybrid.
And i never had any problems before.

Anway i updated to 8.6.24 now , let´s see if it works better on this Version.

Ok, good to know.

That's not what i said. I'm just trying to narrow down the issue.
Whether it's VST related or not is a very important question.

Anway i updated to 8.6.24 now , let´s see if it works better on this Version.

Let me know if the issue is still there.
If it is still there then

• Make a separate copy of that project
• Delete all parts and tracks in that project that are completely unreleated to that problem.
  So ideally you only keep 1 sequence track and 1 automation track and when rendering that 3x it renders 3x differently.
• When you have such atomic project, also delete all unused racks (right-click the + rack button -> Delete Unused Racks).
• Then also delete any unused samples via Project Browser -> Set What = "Samples" and Where = "This Project" -> then click the Options button -> Delete Unused Samples.
• At this point pls recheck that the rendering issue still persists.
• Then save that project as that separate project and zip it and upload it to some cloud drive and share the link to that zipped project file. Or if the zip file is max only a couple of MBs you can simply email it to me.
