Back to the original topic, having wandered a bit for a while: the core issue is that there is no
standard in this case.
There is in fact an international standard (formerly an American standard). (You will have to excuse me if I want to use the word standard
in a formal sense.) There is certainly not uniformity of practice.
The notation used by keyboard makers to identify the physical octave numbers on their keyboards (eg â€œA4â€) happens to use a form similar to â€œscientific pitch notationâ€ but it is a different concept and the two should not be confused. Scientific pitch notation specifies frequencies, whereas keyboard makersâ€™ octave numbers specify keys on the physical keyboard.
I believe the intent, setting aside the matter of transposition done by the keyboard, is to identify the keys in terms of note pitches (normally) associated with those keys.
The physical keyboard octave notation is also not standardized among manufacturers and may even vary between models from the same manufacturer.
Indeed, but this is the same variation in convention we find in designating note octaves where no physical keyboard is involved - it is not a creature of the keyboard business, but rather just another manifestation of the same inconsistency we encounter in designating note pitches.
Thus, if a particular instrument designates its physical key Middle C as â€œC3â€, hitting that key will produce the pitch â€œC4â€ (in SPN) and if the instrument is set to transpose up a major third, that same key will produce the SPN pitch â€œE4â€. Note that this observation is independent of MIDI and is independent of Encore.
