Here is my setting of the Anglican Evening Canticles (Magnificat and Nunc Dimittis) using GPO strings - a good substitute for what is intended to be the voices of a cathedral choir.

The baroque organ included with GPO is excellent but the English cathedral organ is very different in nature (and rarely sampled) so I hope I will be forgiven for using a third party product on this occasion!
I posted an incomplete version of the Magnificat sometime ago, but I've refined it and added the Nunc. One of the members of Exeter cathedral choir has given it the 'green light' for a run through after Christmas - which I'm very excited about.
These are GPO section strings with Ambience cathedral reverb.
