Spitfire Audio Labs
I made a post about this on Facebook earlier this week which seemed to garner some interest so I thought I should share this here as well.
Recently I have been very much enjoying the Youtube channel of Christian Henson, which I highly recommend to anyone interested in scoring or digital orchestral instrumentation. In my viewing the I have been made aware of the Spitfire Audio Labs range of instruments that are available free from Spitfire Audio.

Having given these a try I have been very impressed with their quality of sound and flexibility and would highly recommend them to anyone looking to enhance their existing library with some excellent sampled instruments. The drum kit in particular has impressed me with its flexibility and quality despite having only the very minimum of controls.
Give them a go and see what you think. I hope you will be as impressed as I was.
