Ableton has released The Orchestral Instrument Collection. Ableton is not the first thing that comes to mind when I think of Orchestral music. But of course these instrument can be used for other types of music. I think the strength of this collection is how well it integrated into the host. Most other collection like this are not going to fit right in as well as this unsurprisingly. If you follow the link the video on the site show it off pretty well. It is $600 for 24Gb of $160 for each instrument group.
