Thanks so much.
I knew the "reset all bars", but was arguing, it will reset all changes I`ve made, incl. style- and volumechanges etc. But of course, it`s better to redo those as to type every bars tempo.

I use the 64bit version,thought it runs better.

So every line built with midiarrangement changes and must be frozen before beeing stored.
Shure, the real tracks aren`t affected, thats what I learned first, but I didn`t realize that miditracks are generated new when beeing loaded new. Sadly many work is lost now. So all tracks should be frozen before stored, as they change from time to time loaded.

Sorry, I thought counterwise,that it would be better to answer to one thread than to seperate ones. I respectfully do so further on.

The strings were put on the melody track, but were generated new eventhough, The other tracks are pedal steel, 2 guits, drum and bassline.
The special characteristic basswalk in the songbeginning I`ve put to soloist track, now froze it. So better freeze everything, even though the changes in the realtracks aren`t that much.

Sadly with the copyrights, as there are many "covers" out there(youtube a.s. o.) not owning the rights of the song, as long as they aren`t sold I thought could be no problem. But if so, it is.
Greats from germany
