Logic X Out of tune bug
I work with Logic Pro X every day since it has been released and noticed a very strange bug with both audio and software instruments (MIDI):
After saving and reloading a project Logic Pro X randomly plays audio files out of tune. It is not affecting every track, but some. I checked everything: sample rate, interface (Presonus StudioLive 16.0.2). The strange thing is: after stopping playback, starting, stopping again and starting again and opening the track in the sample window, playing it back there and so on.....everything works just fine.
Today the same with MIDI:
I saved a track some days ago. Today I reopened it. Just piano. Logic Pro X starts to insert false notes and some, not all, notes are out of tune. I checked the arrangement in the piano roll, score and event list. Everything is fine. No controllers, nothing. I even switched to another instrument and internal audio. Same result. I then moved the region to a new track (external MIDI) and played it back over USB and a ROLAND Juno-Di. Perfect. After that I exported the region as a MIDI file and imported it back to the same software instrument track were it was before. Everything works fine.
That's strange, isn't it?
The last two updates didn't correct this bug - and I really think it is a bug, because it happens to new songs and imported songs (from L9), but never happens in L9.
No third party plug-ins are involved! Just Logic! I checked that before.
I wrote a bug report for Apple and hope they will do something about it.
Anyone else with this bug?
