Projects that have soft synths will take more time to load because of the sample library's.
Projects that are "Audio tracks only" are different, they will load really fast.
I just did a quick test:On a typical projects that includes:
35 tracks: (4 Soft synths / 31 audio tracks) Not too many FXThe approx. load time is 13 seconds. (That's from start to open= Double clicking on a Cakewalk project file) Keep in mind I have an Intel I7 4790. Surely not the best or fastest of the I7 family
But not a bad one either.
