Unless you're on an absolute hurry to use the Edit app, I'd recommend keeping this option active. It'll save you future headaches and the classic "Why is Edit showing a different amp/effect than what I'm using?" question made by people who don't let the app make this rutinary task to ensure hardware and software are in sync, specially after updates that introduce new elements like amps, effects, etc...So I've updated to FW4.0 and FM3 Edit 1.05. But now, whenever I open FM3 Edit, it says "Reading Block Definitions. This occurs when saved definitions do not match those in the connected device." How do I get off of this or get whatever needs to be updated working?
