We call Middle C "C5", as do some other companies (eg Cakewalk) http://forum.cakewalk.com/tm.aspx?m=671372

The problem with using C4 is that it leaves the lowest octave as C -1, which implies a note number less than zero.
The lowest MIDI note number is 0 - it seems somehow more natural to call that C0 instead of C -1
Also, middle C is note 60, and C5 makes sense because 5x12= 60

I'm not expecting anyone to change their opinion on this, im just explaining why we have called middle C C5 for 23 years.

Other companies use C4 or C3 so it is a mess.
