Copying audioclip from page A to B problem

in Loopy Pro

When working in a project, copying any audioclip from page A to B, that clip is no longer in sync (it’s a couple of miliseconds off). Phase aligning the clip does not help. Only after saving, closing and reopening that project will play that clip aligned normal. Mind you this project contains many many MIDI clips, faders and stepped dials and many of those are also MIDI learned with CC’s, PC and NOTES on 6 different channels on both on page A and B to allow proper automation.

Interestingly, when I create a new empty project and copy the same clip from page A to B, there are no sync problems. While verifying this while writing this post, copying from A to B in that forementioned complicated project, suddenly no longer causes any latency problems! Perhaps there is a memory leak which causes latency between clips when copied over to different pages and only when a project is running for an extended time in RAM?

FWIW I’m running Loopy Pro 2.0.5 (725) on an 13 inch iPad Pro M1 with 128GB of storage.

    If you have a project where this is reproducible, we would need a copy a copy of the project and instructions for reproducible it.

    Is the clock running when this happens?

    Were the clips’ start/stop trim points edited by any chance?

    The outgoing midi clock was running and set to my Zoom U-44. Loopy Pro is the master. The loop points were not edited / touched and the waveform start point looks exactly the same when zoomed in. It seems it fixed itself now which makes it hard to reproduce. Today I decided to post about it but I noticed this problem twice before and simply saving/reopening the project fixed it. Will post back if the problem returns.
