First of all, congratulations! This update is amazing!!! I am really impressed.
Now, a minor problem… I am not sure if I’m doing right: I’m trying to insert a PC to program 1, for example, but using the Draw tool the line magnetizes to 0 or 4. I could workaround this problem inserting a PC to 50 a bar before and a PC to 30 in the bar where I want the change, then I select both and move the first PC from 50 to 21, deselect both and delete the first. 
Not too complex, but I am sure that I am doing it wrong.
Anyway, I can control my external hardware (a Digitech GNX4) and change a lot of parameters!
Thanks again for the update! I wish the 1.9 version allows me to change formula and tempo, so I will be really really happy.
