all my patches are gone !!!

all my patches are gone !!!
« on: May 18, 2023, 08:27:49 AM »
Hi !
I have programmed almost 30 of my best patches ever.
A few minutes ago, patch number 146 was written then when I tried to save 147, I heard some kind of static through my headphones.
Patch 147 was no more,  instead I hear some random noise. Then I realize with horror that  all my patches from 111 to 147 are gone and replaced by some random parameters. Factory patches seem to be doing fine  and curiously patches above 150 are ok too. Only the sounds that matter to me are gone. I think I'm going to puke...

Of course I have no backup since I thought I had plenty of time and free memory slots.

Is there, by any chance, a way to restore the memory ? WTF just happened ?
Anyone has experienced that ?

Sorry to hear that, I feel your pain. It’s awful when that happens. I haven’t heard of that particular issue before. Was there a power surge or brownout while you were saving?

I lost a whole bunch of patches last year due to a bug whereby if the “factory” button is illuminated then the factory patches get sent via SysEx instead of the user patches when performing a user dump. I backed up my patches (or so I thought) and then loaded up some others to play test. When I went to load my own patches back on, I was horrified to learn that they were just the factory ones.

There was no power surge. I heard a static at the exact moment I depressed the patch number in order to write the memory.
Lesson learnt... the hard way. From now I will dump my sysex every 8 patches

I did have this exact thing happen a few weeks ago. Fortunately I was in the middle of moving patches around and had just done a sysex backup so nothing was lost. But it happened just like you described and scambled all of the 100 group.

Could it have been caused by a mobile phone near the synth? They spit out location signals regularly.

Were you connected to a PC at the time? Could it have been something coming down the usb cable?

Well... I'm not really subscribing to the mobile phone theory and can't see why location signal would be related. FWIW i wasn't on the phone when it happened, and the phone wasn't in my pocket but somewhere in the appartment.
Regarding the USB cable, it's not even plugged in since I have noticed some buzz in the sound signal with it.

I was just thinking about possibilities. Might be that you just have a defective unit. I’d advise emailing sequential support and seeing what they say.
