Here's a couple tips for those who want to be the best assistant out there. (I skip some of the gimme's like "Show up time" and "documentation") For tracking: As soon as you know the BPM calculate the delay times, write them on console tape & stick it above a delay unit on the FX rack Write out SMPTE (or ABS) numbers down for every 4 bars. This will help the engineer determine where everything will go before any vocals are laid. (on the back of the track sheet is great) When striping SMPTE start at 00:59:30:00-00. If sequencing, have the producer start the song at 1hr (with a count-in bar) The count-in helps the song start correctly without any midi-burps & helps for tracking When tracking vocals, document the vocal chain & date it. Put this with the track sheet. This helps in case overdubs are necessary later. Make sure every pencil in the room is sharp. Place at least 2 pencils & a notepad in the studio. Place a bottled water next to the cue box.
