The MIDI standard doesn't define which octave is standard.

This is because the documentation of the two biggest standard bearers, Roland and Yamaha, defines their MIDI standard octave one octave apart from each other.

One byproduct of this is you'll find each virtual instrument developer either follows Roland's standard or Yamaha's standard. You may end up with two virtual electric basses using different octaves of the keyboard.
