Strangest thing, but I just noticed one of my projects was taking very long to save. After some hunting and pecking, I found that 1.) The project size was unsually large, around 75mb and 2.) The main reason for this was using Action Strikes by NI.
Specifically, each instance of action strikes was causing the project file size to increase by 6mb! This is much more than the average Kontakt synth.
Any solution for this or is it some bug with Action Strikes?
