Probably too late for C7, but it’s worth mentioning periodically…
Apparently, ‘Middle C’ is something like ‘Concert A’ in that it varies between cultures. In Cubase, what -I- call middle C is C3. Apparently, for Germans/Austrian software companies, ‘Middle C’ is what I call ‘C4’. This has made for all manner of confusion for many of us over the years with various sample libs and keyboard controllers, etc.
I would sure like it if there was a Preference where one could specify the midi note recognised as C3 or C4.
