It's from Bonners Music, U.K.

Hopefully, they'll have another demo soon featuring acoustic and orchestral sounds.

As I stated earlier, I had really hoped they would demo the acoustic and orchestral sounds, including choirs. As you can hear at the end of this video, they are going to demo the orchestral sounds next! Thank you, Bonners Music!
