OK, newbie here. I found some Wurley A-200 sound demos that seemed fantastic. I read the info regarding the detail work that went into this VST instrument and it seemed legit. So I made the buy.
But in the process I discovered that Native Instruments/Kontact is completely unsupported directly, there is no email of phone contact to be had. There are instructions on the site to help, that is all there is. Eventually I was able to install and use the A-200 instrument - but ONLY after installing the NI Kontact 6 Player. Which is actually rather convoluted considering the operation of the Steinberg and Waves VST instruments. But it is what it is. Too, I will add, I could not get the A-200 to play back previously recorded midi track from the Steinberg VST instruments. But after the third go round, closing C10 and opening it, it now works.
And BTW, NI is all VST2.4, they have not upgraded to VST3 and nowhere do they publish this info. However, it is 64bits and it will work in C10.
