When MIDI became a thing, there were two schools, Yamaha with C3, Roland with C4. Cubase’s Middle C has always been C3, as are most of the old school sample libraries and synths. MIDI instruments have almost always hovered around C3, Roland was always the odd one ‘back in the day’ with it at C4. Can’t recall where the middle was on my Juno 106 though.
Logic lets you switch between the two, but Cubase was always C3, which matches up with all my hardware here (except my Roland XV3080 haha)… It’s still the same note (Note 60) just different notation.
