Rendering and sync

[4am]

Hi

When I render a long midi track to audio,it gradually loses sync after a while. I can check this when I import the rendered audio track and put it next to the original midi file.

It is not a new issue, and it doesn't happen (or at least it is not noticeable) on shorter files.

I'm I missin something important?

Thanks

Are you freeze/flattening or recording on a new track via resampling?

If you are resampling the small amount of latency may throw it off. However freezing and flattening should be no different.

no, i'm simply selecting the zone of the track i want to render
then "render to disk"

should i resample it? (in this case it is a midi track)

[contakt321]

No, Freeze/Flatten is the way

I have had this happen before. Can you save the patch on the VST, delete it/then re-place it on the same track?

In the past I have had certain plugins lose tempo sync somehow and get delays or LFOs going off.

thanks i will try
the same happens also with audio, and not only to midi
you mean that i should always export my tracks freezing them?

Ignore my suggestion above.

Here's what I think the problem is;

Warping

When you render it, it's converting it to warping, and might be using a weird mode. IF you turn warping off does it match up?

i've turned warping off

the sync is now ok, but i have a delay on on the original track, which is midi

the rendered track is in advance compared to the original
and both starting points are set to 0
