I am new to making tracks ready to be mixed for post production. I am working w Nuendo 2 recording tracks on a project that will be mixed at another studio. I am supposed to make the tracks all start at the same time, obviously. I had this under control until the guitarists started doing tracks with very short leads or other BS when I was not around. Ughh!!! When they did so they started the recorder where they wanted the new part and recorded. Now I have little clips all over the place and I don't know how to fill out the tracks so the wav. files all start at zero. The guy doing the post work made it sound easy but I don't know what to do and trying to get support help on weekends when I work is impossible. Any help would be appreciated.
