I found the same exact bug two days ago. 

In my case the thing that went out of tune was an FM Stat bass. I had 
5 different sequences from E1 to E5. Whenever I went to E5 (FM Stat 
in track 1), if I went back to E1 (FM Stat in track 1), track 1 on E1 
was completely out of tune. I could get my sound more or less back 
again by lowering the LPQ, but it seemed to me there was more 
changes, as the sound wasnt exactly what it used to be. It only 
affected track 1 on E1, all the others were fine.

The parameters on track 1 E1 when out of tune have the same values as 
when in tune. I could not appreciate any change, though there could 
be.

I tried making a different kit via COPY TRACK, but it still got out 
of tune once I went to E5 and back to E1. I tried making a new kit 
copying the parameters by hand, but it still went out of tune. I also 
tried copying the pattern to E6, but it still went out of tune. 

The only way for it to go back to normal was powering off the MnM. 
The only solution I found after some messing was simply make a new 
sound, with a different machine.

I'm not sure what triggered this bug, but it started happening after 
I did two things: I changed one machine in E4 track 1 (SW saw to FM 
Stat, I think) and saved the kit, and I did a new pattern in E5. 
After that, its when the bug appeared. It may have nothing to do with 
it though.

Its a very nasty bug. I tried to post it on the Elektron Users forum, 
but it gave me an error and I didnt have the patience to write the 
post again.

Hope the guys at Elektron solve this one, it sucks for playing live.
