The plot thickens.
I decided to create a new song in Sibelius, for piano and violin. The total length was 1:38
I exported the file as audio at 44.1 khz. Then I exported the midi and checked both in the Mac music player, they both said they were 1:38 in length.
But then, I dragged the audio and midi files into Logic, and you can see the results of what logic did in the attached screenshot.
The longer audio file maybe due to the reverb tail. The audio file has reverb, the midi does not, but I also had the sustain pedal on the piano.
So I got rid of the sustain pedal notation, and turned off all reverb in Sibelius, and re-exported the audio and midi files like before. It made no difference. See screenshot 2.
So for some reason, Logic is adjusting the length of the midi file. In logic, the midi runs for 1:33 and the audio, 1:38.
Got be baffled.
Any thoughts?
