So I've been considering a big orchestral library for a while and I settled on BBCSO pro last week. Right now their black weekend deal is 40% off o I pulled the trigger yesterday and threw in thir proprietary SSD to house the 500+GB of high res samples. They threw in a kontakt library worth about what the SSD costs. Haven't tried it yet, because I decided to give the smaller Core version a whirl on the concerto I'm writing and DAMN!
Listen, I cannot recommend the BBCSO highly enough. I know Discover can be had for free, but just Core is worth it. If you want to add orchestration to your music and you KNOW A BIT ABOUT HOW ITS DONE, this is for you. If not look at Abbey Road maybe, or I also was partial to the Studio Orchestra soundwise for adding to pop productions, but Abbey road is like ready to go sections and combos with a great pop studio sound so if you can't orchestrate and just want vintage strings a la phil spector and George Martin/beatles? Bang. If you have the Waves Abbey Road chambers (also on sale) you can get a lot out of that. And like the BBC Abbey Road is a dedicated plugin. More on that anon...
However, if you want absolute control for more complex orchestral work? Or you just have the patience to work it all out? BBC sounds superlative and the proprietary plugin is a ream to work with. I learned the basics in an hour and had all my woodwinds for example responding with custom velocity curves and a shared technique trigger template that both worked well whether playing the keyboard or drawing in notes. Unlike Kontakt the interface is highly scalable both visually on the GUI and content-wise for collabs with people who have pro or discover. The Core version runs fine on my old i5 machine in multiple isntances and my current i9 machine doesn't even break a sweat. And oh those legatos and portamentos... multiple types of pizz, bow slaps, multi tongue techniques andif lucks aren't your cuppa (its brit orchestra, so pour tea) staccatisimo, super staccato wind and brass stabs. If you can't find a use for that? Well...
I cannot recommend this highly enough if you want to add some acoustic music into what you're doing. ANd not just pop/rock stuff. This orchestra could be at home in an epic club banger, particularly like future disco.... or if you want to do some techno? Make a cute little arrangement, print it, chop up the stereo mix and get all strings of life with it! I'm telling you... Buy the Core to try out. it will give you new places to go. Iw ould not pass on this deal (and didn't). I don't usually go in for this stuff, but something of this quality for these prices? I think this is my favorite plugin of all time. Grnted, I own a lot of synths, I can't fit the BBC orchestra in my house though... and I lvoe classical music, so.... YMMV
EDIT: the Core sale price is a paltry $269.... I've had bar tabs bigger than that.
