As I commented on another poster wondering if it would be possible to mimic Tallinn with one of OT's Ark choirs: you could technically shape the sonic envelope of one of the samples from any of these libraries to get in the "ball park" of Tallinns straight articulations but that's as far as you'll get!Oh no! That's not the answer that I was looking for haha! I just wanted to know about the choirs, not spend more money on the whole library.
I already have Liberis, Insolidus, Requiem Light, 8Dio Studio Sopranos, Mercury, and Olympus Elements. I'm wondering if Tallinn would would give me something that I don't already have. I was only looking at the women's voices, maybe the men as well, but now I will look at the rest of the library.
Tallinn's sound, even with the straight sustain articulations, stems from the unique marriage of the Tallinn singers singing style captured in that Niguliste church: without either element it wouldn't be Tallinn!
So yes! Tallinn would definitely bring you a different choral flavour but only if you are aware of why you would seek it's very particular choral timbre to fulfil a certain roll within any given composition.
Also you're getting arguably one of the most beautifully captured church/cathedral organ libraries ever plus an extremely useful strings library to boot!
To my ears Tallinn offers a very unique yet highly usable set of instruments. I believe, once this library has been updated to iron out a few technicalities that have already been pointed out by early adopters, this library will become a classic but also a library that can in fact be used to great aplomb without necessarily being instantly recognisable: something which for those composers looking to maintain their own unique sonic footprint is a rare tool to have to hand!
