No it's not the direction from which SANTA is coming or leaving. Rather it's the name of East West Sound libraries and I found the collection of Hollywood Strings in my stocking very early this morning (about 2am by the time the files had downloaded!) I've read about these libraries of samples and performance interfaces before but actually using them in a production is incredible. The realism is phenomenal as is the control given to the composer - no wonder so many film score writers and arrangers use them.
And if you're concerned about the price tag of these libraries you'll be pleased to know they currently have a Christmas sale on, for all the other SANTA Composers out there.
