Yes this is rather confusing, but as with many things regarding C7, I’m reserving judgement until the new build is complete. We’ve been rather put to task because C7 is a rebuilding of the GUI and they (perhaps to get the jump on other vendors, need for capital, or pressure from Yamaha, for whatever reason) pushed C7 out the door before it was finished. We’ve still yet to see the new project/arrange window which as I understand is quite different to the existing one. I am pretty sure that a number of incongruities as well as the avoidance regarding some issues are directly related to this situation.
Regarding the original theme here, it may be that currently both disable and off have to be supported - eventually one will win out over the other - we’ll see.
