You should be asking this question of the manufacturers, then if they say yes and it does not work, you have come back on them - ie it will be easier to get your money back.
Further to the reply from John E. Baker, I looked up the program. Interesting. However, Magix products are not on the list of tested programs.
Do you already have EW Quantum Leap? If so, download the trial MMM and try it out. I would suggest however trying Magix Samplitude Studio as you may have more success and it has more features and possibilities than MMM. A couple of users of Samplitude Pro have used EWQL. See this site and do a search or post your question there.
Its the other way round, I have MM2014, but see that ewql synphonic choirs is doing a half price deal, hence the interest. I does look amazing and would be great if it would work with MM, but if push comes to shove I guess I can also buy reaper which it should work with and is very reasonably priced. However I do like MM and am used to it, so to speak and have a few soundpools etc etc.
Do you have the Music Maker 2014 bundled with Music Studio 2? I got it all both together. If you are not sure, check your account / licenses. Music Studio 2 can load VSTi's. Just have to be aware you're entering the dongle world with East West and would require an iLok dongle.
