When I collab with Bapu for example, he supplies a 'tracking shell': a .CWB file with markers for verse, chorus etc and a scratch track to work to. I record my parts against the scratch track, send him an MP3 for approval, then do it again..and again..until he's happy..then send him a WAV file.
At what stage is this "happiness" achieved? I've been at it for 9 months and 2674 takes so far and now the time sig has changed again......
