I only ever had Kitcore and found it useful. I preordered the Drumcore 4 light as a 64bit player for that. Of course in the time I have been waiting I have added much and probably wont use it frequently.
I don't have much interest in the audio loop part of the program.
So, installation seemed to go OK but very clunky. Now I need the migration program to Import my Kitcore 3 stuff, its not in my downloads. Lets see how responsive support is?
