I just bought the 690 Virtual instruments from DSK and I want to use them in Magix Music Maker 2015 Premium (Production Bundle) but I don't know which type of file I should download there's
sf2(Soundfont), Kontact/ wav, Reason NN-XT, Giga sampler, sampletank, sfz, EXS24 or DirectWave(FL studio).
Here's the site if that doesn't help.

Just so you know I also downloaded one of their free ones that worked perfectly in MMM2015 and it was a .dll file.
