I have a song with two vocal tracks to which I have applied Melodyne (Editor). Playing the particular vocal parts everything seemed fine. However, if I play the song from the beginning the vocals are delay by about .1 sec. Bypass Meodyne and everything is fine. I've even spotted it down to a particular time: start after 10.86 sec into the song and everything is fine (even with Melodyne not bypassed) . Start before 10.86 sec and I get a delay. Very strange. This is a very simple song. Shaker, Djembe, Bass, 2 Acoustic guitars, Electric guitar, 2 vocal tracks, Vocal bus, Reverb bus, Master bus. I don't see anything at 10.86 sec that could have triggered this. Update: Windows 7 (64bit), i7 2.8GHz, PT 9.0.0, Melodyne Editor 1.2.0 (32 bit) RTAS I have saved, closed, shut down, restarted, reopened, etc.
