Uploading samples to the Blofeld is a bit of a slow hassle, you won't be doing this very often. Changing out samples obviously affects Blofeld patches that use them. Waldorf's Spectre app to organise the samples before upload is very basic and you may want to edit the xml files it generates manually to reorder stuff. That's all not a problem with this specific product though.
Word of warning: write down your product/response codes. They can also be used for the special edition Waldorf vsts on the disc. (At least I got those with my order.) And when I say "on the disc", I mean "you have to download from the website" because the installer/registration process on the disc doesn't work on modern 64 bit Windows and tells you that by outputting unrelated error messages.
Very happy with a sample drumkit in my Blofeld now!
Nice addition for using samples as an audio source/oscillator in your sound patches. Quality of samples is somewhat standard, and the variety of the samples themselves limited. The purpose of the samples is for them to be used as the foundation or elements of a richer sound palette; as opposed to standalone samples like one would do with a typical ROMpler. Overall, a rather pricey upgrade, which nonetheless adds considerable flexibility to the sound manipulation capabilities of a waldorf, which makes it worthwhile.
