I am new to the world of sound banks and I am really satisfied with this software,
instruments are incredibly well recorded. I use a simple usb midi keyboard "plug & play" type with this software.
The software provided "Play" is out of date, you have to download it from Sounds Online website. Then simply run the installer on each disc, or if, like for me, it didn't work, copy in one same root folder :
-the "instruments" folder (disc 1),
-ALL the "samples" folders in ONE folder (one in each discs).
Then just add the root folder to your favorites in the standalone QL Silk application.
Have fun
