I'm working on building a track for the Wintley Phipps version of the classic song "He" . Like any Wintley Phipps song the big challenge is getting the orchestration right. You can't just use a string pad and call it a day. You really have to listen closely and repeatedly to just a couple bars at a time to hear all the movements and to get the right instruments. And each instrument has to be set to its own output so you can crescendo and decrescendo as required. For a lot of my sounds I use the Miroslav Philharmonik2 or Kontakt Komplete
