I've been using SF13 trial for a couple of weeks and I noticed that there is no longer Izotope SRC included? The last version that I have is 10, and it has it.
Honestly, I don't think I am going to upgrade to 13, it's just too expensive for too little features I would actually use. I want to upgrade but at $199..
Several other reasons that the price is not worth it:
experienced more crashing mostly when opening files from file explorer (win10)
Izotope Ozone Elements is not the latest version (7 not 8)
Loses the older Izotope plugin suite, which also includes a nice reverb that I liked.
Prospect of future updates being pricey for little features, yet badly needed stability.
