This bug was reported here btw.
We understand your frustration,
without your video, it is harder to pinpoint exactly what you mean, thank you for sharing that, this appears to be the issue that was reported about lock tracks. The bug is that the locked track is starting over correctly but the non-locked track is changing its starting point. **EDIT
I will report this as well, it could change timeline, it may not, but nevertheless it is very helpful.
We understand this is a very specific use case to your playing and it is very important to you.
For possible workarounds while we work on this: Is it not possible to do what you’re trying to accomplish with both sync start and length on?
Also, have you tried recording the same phrase twice in each part almost identically? I understand this defeats the purpose of the lock track in your case, but as we’ve stated this particular state (locked track and offset with non-locked tracks) causes issues, but there are ways to work around it while waiting on the feature to support your use case.
We have not stopped working on the Aeros and while we always appreciate candor, we also appreciate keeping the conversation constructive and working with us as we work with you to fix your issues. Please refrain from using all caps (as we ask in the forum rules) or multiple exclamation points, it comes across as screaming and can alter the tone of your message, a great alternative is to use itallics.
We also want things to get done! They also are getting done!
Thanks for reporting
