A couple of evenings ago I recorded a singer do 4 vocal tracks.. It was an a cappella recording.    He sang all 4 parts.
The 4 tracks were obviously all in harmony with each other.

He first laid down the melody track - which I made sure started at the beginning of the region  - and then we used that as the cue for him to sing the other parts "against".
I noticed that some were a nadge out of sync or  a nadge behind the beat but as he was only using the melody as the cue I didn't have to worry too much.  The sync issue may have simply been him not quite being on the spot when listening to the cue. i.e. he was waiting to hear the cue before singing his note if you like  .. A perception or insecurity thing by him  maybe??  Dunno.   The sync issue was only minor and barely audible but  annoying for me because I was looking for it.

So I just went in using the Logic 9 flex edit features and realigned all the singing on the beat and to each other etc. using the Melody as the  "master" to work from.
Only took me a few minutes (maybe 1/4 hour)

I didn't notice a recording speed issue just a sync problem with the cue track/beat.
