differences in play times of exported tracks with exactly same notes

Nobody has claimed this yet.

When you "export tracks" and check the time lengths for same notes, bpm and output format settings, you will find that the artifacts are with different play time lengths and other attributes.

Open the attached sample, export the tracks, and load all .ogg files in Audacity.
Then see the ending times. In my opinion, they should contain equal amount of playtimes.

How to reproduce? Please consider the project: [exports.zip](https://github.com/user-attachments/files/23597248/exports.zip)

Updates: [exports-with-automation-bar.zip](https://github.com/user-attachments/files/24019535/exports-with-automation-bar.zip) does not cause this issue.

Copy some notes, eg 2 bars long to some default instruments.

- Then apply same channel number to ensure they have common effects, if any.
- Export all tracks using the File > Export Tracks menu.
- Open all artifacts together in a stack using Audacity or MP3Tag

They have different play times! causing overlapping sounds.

Each instrument seems to have a different bitrate output

Start with the File > Export Tracks workflow and reproduce the issue using exports.zip, then load the generated .ogg files together in Audacity to compare their ending times and output attributes. The fix is complete when tracks with identical notes, BPM, format settings, and channel effects export with matching play times without overlapping playback.
