I'm not sure I agree with the (joke) statement about pro's not needing undo, but it seems to me that undo would be rather difficult to implement properly in Scope.
Having all your actions in the application pushed into a single stack would be really confusing and problematic, having undo per device could lead to erratic behaviour. There are certain places where it might make sense (VDat/Cutmaster perhaps, a sequencer module, etc) but for things like changing routing, adding/removing modules, and adjusting parameters I can't think of many audio apps that will 'undo' removing a synth, or 'undo' changing midi assignment and so on.
Of course to be fair certain apps like Bidule manage to get undo/redo to work with many things, but it still is certainly not a global operation.
Just a word of warning, some users have experienced corrupted projects due to teh backup save feature. I think there's something more at work with this though, I had this problem once and things have worked fine for years now for me.
valis youre right. would be confusing or problematic. that is also good idea saving as different name. thanks At0m
another thing:
do you have EQ preset at planetZ?
