middle C

[House de Kris]

What's in a name? Note 60 (or 3C in hex) is still note 60, no matter what you call it. I suppose it boils down to what do you want to call note 00? If you call note 00 C0, then note 60 would be C5. But, if you call note 00 C-2, then note 60 would be called C3. Either way, note 60, whether you call it C3 or C5, will sound the same.
