It's a good translation but actually takes some creative license in places (i.e. adds features/details that don't exist!)
I don't really understand where "features/details that don't exist" are added?
In the above translation from German to English? I know German a little and it seems that German manual states same as translated above.
BUT - the problem is not how good or not is my (or via online translators) translation, the problem is that I don't understand why German documentation is much more detailed and full, than English one?
Maybe I do not know the Sequential market but my guess would be that more synths are bought by non-German speaking people so having English manual with lower quality is at least surprising.
Cheers!
