@DanielAyo @Yoshiaki_Watanuki @henrique_staino So I finally found some time to look at that issue in detail, and as @Laturec said it’s quite clearly a Resolve issue.
Note that it properly work on macOS, only Resolve on Windows seems to have this issue.
The issue is that Resolve only look for changes in the Creation Time metadata of the file, instead of looking for the Modification Time.
Softwares like SpectraLayers, WaveLab, Acoustica properly update the Modification Time, but they all don’t work with Resolve Windows.
RX on the other hand also change Creation Time while updating the file, and it works with Resolve Windows, but this is clearly malpractice. And I must say I feel uncomfortable introducing malpractice as a workaround for an external software…
Meanwhile the workaround you can use is once you’re done with your edit, open PowerShell (its a Windows utility), and type:
(Get-Item "C:\path\to\the\edited\file\from\resolve.wav").CreationTime = Get-Date
This will force Creation Time update.
I sent an email about that issue to one of my contacts at Davinci, but I also strongly suggest you all report that issue to Davinci as well to make sure they fix it.
