If you love M-Tron Pro, (which I do) you are going to adore this. The sounds are every bit as characterful as the Melly, but generally far more refined, and therefore essential for creating more realistic ingredients to your sound mix.
I am using their string sounds in preference to modern sample libraries because they sound so much more characterful. If you use acoustic samples in your work then you need the Chamberlin sounds, and this is the best and most comprehensive way to access them.
