Cubasis update in iOS 9/10

Is it safe to update if you don’t have iOS 11?
Thanks

Hi Ivan77,

Please note that some of the feature additions require at least iOS 10 and/or iOS 11.
Same as Apple, we recommend to use the latest available iOS version.

Best,
Lars

Not sure if this is right…
I can say, that Cubasis 2.4 on 9 3.5 crashes, when you got note repeat or use the midi editor.
Maybe someone could help.
