I think the reason why is simply, Halion 5 is not that popular, due to the cluttered Gui, Extreme learning curve, Cpu Hog and Many outdated sounds, Not many people are interested. On the other hand , I wish I had Purchased Kontakt Instead. search youtube and see how many tutorials there are on halion 5 Not many, It is as though Halion does not even exists, Yet there are many tutorials on Kontakt. I have since tried Kontakt and must say I like it Way Better Than Halion 5.
I must Mention That I really Like Halion se And Halion sonic 2. I only purchased Halion 5 for the sampling, It seems to do everything else but, the sampling Seems as though it is hidden amongst cluttered complexities. Perhaps if there were better tutorials on how to use the software my perspective would change, but as it is now, since no one wants to support the learning of it, due to not enough interest in the software compared to Kontakt and motu mach five. I am investigating on how to sell my license for Halion 5 for half price or best offer. Interested ??
