I'm actually trying to purchase Native Instruments Massive but I tried it out before I am buying and it appears it does not even work in ableton. The stand alone works fine but as a 64 bit VST it does not work, the knobs are frozen and buggy, basically all the knobs are not really working. So I'm a little skeptical to purchase. Also Sylenth is not working as well. Are these problems solved when purchasing? I have a feeling the software will still not work properly and i'll be out some money. Has this ever happened to anyone?
