I think the octave names are arbitrary - at least according to this:http://www.harmony-central.com/MIDI/Doc/table2.htmlI've seen middle C called both C4 and C5 by different software (thoughI don't know whether to trust it). > 3) which would be the correct range (in note numbers) from a 88 note> keyboard? Um, I guess it depends on what a piano can do... A up to C, isn't it?
