Music Studio not wort

Forabout 5 months I have not been able to use Music Studio. Anyone know what to do?

It is a sin that the writers of Music Studio haven’t
found a fix for their app. I was a Senior Programmer then Sr. Systems Analyst. I would have been fired if I let this happen on one of my projects.
So please get off your BUTTS and FIX MUSIC STUDIO before I demand a refund for the app and all the instruments I bought and it WAS.NOT CHEAP !!
PS. I have an IPhone 6 PLUS and it worked fine until someone messed it up. FIX MUSIC STUDIO before I give you a horrible app review and demand my money back.
Did you ever hear of the B. B. B. ?

The update to version 2.11 resolves this issue:
