You’re not alone !
^^
Last year a friend of mine reset his A4 by mistake, loosing months of work. I commiserated, knowing the feeling (plus he was a few weeks before an important gig), and explained him with a teacher tone that he should backup more often (he had never bothered doing so).
So I helped him backup his Machinedrum, and load a few free patches from Elektron…
Back home, I figured I had not made any backup neither on any of my machines, and that it should be a good idea to do so.
First one I took was the A4, I saved the project, or thought I did when in reality I reloaded it to nothing: it had never been saved.
In this project, I had 2 years of Kits and Patterns carefully done… Some of my tracks are gone for good, and would-be ones gone like they never existed.
I was so pissed of at me, such moments are highly frustrating I wanted to break something.
In the same time, my inner self was laughing at me for being so full of myself when telling my friend he should save his work.
So yeah, I got your feeling.
Now I don’t live in the past, most of the patches I loved 2 years ago seem lifeless to me now, I guess I made some improvements.
Don’t look back in anger, I’d say: pleasure in music is the path not the destination ^^
