I agree with DI that "if" they did have auto save it needs to be optional and default to not on... it wouldn't be bad if there was an "undo last action" button. Here's a real life observation why... now that I'm comfortable getting around my Helix, I'm moving quick to edit my blocks... although the joystick is nice, it also adjusts parameters by twisting, so when you're pressing left, right, up or down, it will sometimes accidentally spin as you're moving across blocks. If you're not paying attention, you can change any block and loose the parameter adjustments you've made (like if you accidentally switch an Amp model that you've been tweaking for a while). I have to admit, that became very frustrating last night. Save Often!!!
