Thanks friends!
I am not freezing AZ Controller yet. I have registered on "Plan B" and my forum will stay in tact.
But I will try to find some other DAW. While blamed by many for pure Control Surface support, Cakewalk is the only one with dedicated controller SDK in public. The only other DAW which has something in this direction is Reaper. But I have asked other 3 actively discussed alternatives, I do not even need a public SDK, AZ Controller is closed source and so "compatible" with NDA interfaces.
The code will be reorganized/rewritten once I find another attachment point. It will take time (a year... the first release of AZ Controller was also after one year of development, since I can only use a part of my free time for that).
