We performed tests with the latest version of the software on both Windows 10 and Windows 11, using two different WAV files. We did not observe any playback differences in the TimeLine between the two Windows versions. Are you using the latest version of the software, as some improvements have ...

FYI, you could try the "Windows 32bit (x86)" version of the software because normally Windows ARM is able to run applications for this type of processor

Not in a simple way. Maybe in a future major version.

Done for next fix file.
