Hi everybody,

I have a weird problem with a mix. When i listen to my mix in Cubase 10.5, everything is fine. But when i export it (MP3), a weird thing happens : the piano (a midi instrument, VILabs Ravenscroft 275) disappears. It's there for two thirds of the song, then goes away in a quick fade out.

How is that even possible and can i solve that ?

I am on windows 10

 

I almost never bounce a multi-track daw project to mp3 directly; always wav first. So I looked this up, because it sounded like a pretty strange issue to have, in any DAW.

Try exporting it as a wav file, then listen to the file. If it also happens in the exported .wav file; it is some "normal" problem. It could be hidden Automation, "voice stealing" happening with that part because your plugin is running out of polyphony or other resources. It could be a demo version of that instrument causing a normal demo version audio dropout situation.

Those are all the normal things you would check, because they are problems in your project. The easy workaround would be to just bounce the piano part, loaded into a new audio track, disable the plugin channel with the issue; and then bounce it how you wanted to, straight to mp3.


But if it plays the exported .wav file correctly, it is due to a possible bug in the ~v10.5 mp3 encoder. This could be way faster to figure out than the normal reasons; but it would also be the one problem that might be very easy to overlook. Convert the wave file to mp3 how you wanted, problem solved.
