Yesterday I added some patterns to an existing project. Even named them. Today they are gone.
I think it was caused by pulling the plug instead of shutting down with the power button.
Can anybody confirm that? I was able to reproduce it by doing the same, but not sure if it’s just my unit.
Of course there was a great pattern which I would never reproduce again 
. I guess it just cannot be recovered right?
Yes, turning off the unit by holding down the power button initiates a save. Unplugging it does not, and you lose any patterns you just created.
Ok it’s not just me then. I have other elektrons, where this does not happen, so I wasn’t expecting this behavior…seems like a bug. An important one actually.
Not a bug, it’s mentioned in the manual (top of page 13). The Model series don’t use the same kind of memory management as the other devices.
I found that entry, but it’s kind of innacurate

For example, if you connect the Model:Samples to a power strip that you then use to switch the device off, it will revert to its last saved state when you power it on again, and any unsaved edits will be gone.

My edits were saved, I had saved 3 patterns, all with name. Maybe the manual could me more specific, stating that you need to save the project after saving the pattern if you don’t want to lose anything
That’s interesting, because I was pretty sure I tested that scenario and got the opposite result to you. I may have to go back and check.
I’m a bit confused - you say you had saved 3 patterns with names. Therefore they would have been saved, regardless of how you powered down afterwards.
I’m confused too…but I can tell you the patterns were saved (with the save pattern menu, where you assign the name too), and lost after pulling the power plug.
saved the patterns but not the project? I don’t know the save structure on the models tbh, just I’ve seen u can save individual patterns in the menu, as well as save projects.
might be a thing. maybe if you save patterns you’ll be able to load em to any project, thus reload em to your unsaved project. maybe not like, just a thought
You can’t save patterns outside of a project on m:s or m:c.
But I do wonder if the OP has found an odd route to saving a pattern into a project that has not itself been saved ? However, in my experience if you try to save a pattern into an unsaved project then you’re forced to save the project first so 
The project was already created, the patterns were saved to the project, then lost after a forced shutdown.
I just don’t see the point of a save pattern feature if you are then required to save the project if you don’t want to lose anything. It’s a poor user experience.
aye, what’s the point of pattern save? I’m sure there’s a reason, I just can’t think of it 
I don’t have my samples with me. is there a load option in the pattern menu when u click on the name?
I’m absolutely positive that I’ve done that exact scenario, but found the patterns WERE saved after a disconnection of power. I’m not trying to deny your experience, just saying there must be something else going on in your case.
Could be my unit…I submitted a ticket just in case. But I was able to reproduce the behaviour twice, so it’s real.
It saves the pattern permanently to the project (on the +drive) in my experience. Otherwise the pattern is just in the current memory.
Did you reload the project when you turned it on again? The way projects work on Elektron gear is like snapshots of the machine’s memory; it doesn’t access the project storage unless you request it. So when you power on again after not shutting it down properly, the machine’s memory state resets to how it was before you powered it down, regardless of whether or not you saved the project.
Actually just guessing here 
but it seems to make sense.
