Hi
I'm a bit confused about midi note numbers:
1) am I right that the midi note number goes from 0 to 127?
2) which note name corresponds to 0? C0? C-1?
3) which would be the correct range (in note numbers) from a 88 note
keyboard?

1) am I right that the midi note number goes from 0 to
127?
Yup
2) which note name corresponds to 0? C0? C-1?
I think the octave names are arbitrary - at least according to this:
http://www.harmony-central.com/MIDI/Doc/table2.html
I've seen middle C called both C4 and C5 by different software (though
I 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?

My real point is: I believe the octave names to be
arbitrary.
Then, if I'm writing an application and want to conform to the majority
of apps, what do you and others here find the most usual. Let's take
midinote 60 (sits on the middle of my evolution keyboards), what would
you call that? C5?

Someone on #lad said yamaha is one octave off from about everyone
else. I guess that would be one octave up. Depends on if the first
octave is 0 or 1(?).

The octave number range is configurable in Rosegarden (just to make
things more confusing). The default of 60 = C3 is probably because at
least one of the developers started out with Yamaha equipment.

To the best of my knowledge, the MIDI standard just says note number 60
is "Middle C". It´s completely arbitrary where this middle is. Some
manufacturers take C4, so the lowest note is C-1, others, most notably
Yamaha, take C3, so you can go down to C-2.

Well, being a saxophone player (in the past) it doesn't sound *that*
crazy to me. Why? The sax (usually) is a transposing instrument. Tenor
or soprano sax are tuned in Bb, alt saxophones are tuned in Eb. If you
put your fingers in the "C"-position, the actual frequency coming out
would correspond to a Bb or Eb on the piano, depending on sax model.
And of course with tenor and soprano sax the same finger settings
also result in a completely different octave.
Now what should midi do about it? Remember, there are not only midi
keyboards, there also are midi wind instruments, midi guitars etc. and
there are keyboards with various numbers of keys.
It sounds sensible from a keyboard point of view to just put 60, which
is about the middle of 0-127 as the middle C key. Where this middle C
key is, of course depends on the keyboard model.
For a software synthesizer you don't have a real middle key, you only
have frequencies. It makes sense to spread out the available 127 pitch
numbers so that they span most of the pitches that are musically
useful. The lowest "C" that is useful seems to be the one at about
8Hz. The C below that would be at about 4Hz which is not perceived as
a pitch anymore. You get to use the ~8Hz as lowest C if you define
pitch 69 as corresponding to 440Hz.
On the other end of the scale you get about 12500 Hz for a midi pitch
of 127. This is about half of the nyquist frequency at 44.1kHz
samplerate so there still would be a bit of headroom. However there
won't be a lot of headroom: You will pass a 22.05kHz Nyquist at a
pitch of 137 if you interpolate the midi formula for 69=440Hz this
way: mtof(137)=22350.6
So using "69 midi pitch := 440Hz" in a software syntesizer as default
range makes a lot of sense.

I believe it depends on the instrument. On the piano, C1 is the first
C, which makes middle C C4. On a pipe organ, however, which generally
has 61 notes on each keyboard, C1 is the first C on the keyboard, which
puts middle C at C3 which an 8' stop, which is the standard footage
when counting notes. I guess from what others have said, Yamaha uses
the pipe organ numbering (which makes sense on most synthesizers with
five octave keyboards), while others are using the piano numbering.

This thread has explained to me why I'm constantly confused as to the

software that uses a MIDI keyboard that, while A=440 is a sane
default, there are musically appropriate reasons for variations in the
range of A=415 to A=446+ - allowing a slightly greater range of
variation (say 400 - 450Hz) could also be useful. I tend not to use

Indeed. I find it amusing that there is a suggestion that
counting from '0' is unintuitive in a forum where things we call
'notes' are counted in sets from 'A' to 'G', but starting at
'C'. :-)

Some basic thoughts on note numbering.
a Note is a Frequency; ie A440
A880 is the A note an octave above A440 ie frequency doubles
On a piano, the lowest note is an A; often piano players call it A1
In that case, A1 (name) is A55 (frequency).
Notice that the frequency description of a note sounded is not
arbitrary; a plucked string has a fundamental frequency, which
we use to describe the sound.
Western music notation is based on the idea of note names; ABCDEFG
A1, A2, ... are octaves apart. Note that 1 2 3 ... in these names
are arbitrarily assigned. We could (and I think some do) call
A440 A0. In that case the A an octive below would be called A-1, and
it would make prefect sense as long as folks knew what A0 was.
In brief, the numbers in note names are arbitrary and based on a
logarithmic scale of frequencies. Where the zero point is on that
scale is where the midi note numbering confusion arises. And the
confusion exist for instrument players in general.

I strongly agree. Isn't that just saying that an instrument should be
tune-able. Horns have tuning slides; guitars have pegs. My soundcard
has the capability; software that claims to support it should have a
tuning slider, peg, widgit, command or something.

Might I suggest that, since there is genuine variability in what
people name it, that you make this a configuration option, with
a sensible default (e.g., A4)? This will fend off complaints from
future users who want it to be 'A3' or 'A5', although those
who call it 'Monty the Middle Note' might have to lump it.

http://www.ibiblio.org/emusic-l/info-docs-FAQs/MIDI-doc/MIDI-Primer.txt
And, getting back to the original topic of note numbers there's this:
http://www.harmony-central.com/MIDI/Doc/table2.html
found in:

(I know I'm not the only one here who knows how to use google, but
thought I'd send the links as long as I already found them.)

Just like how some apps use MIDI channels 0-15
and others 1-16.
Totally irritating.
I was just thinking about this these days (as I started to write a
simple midi editor for some of my gear). First I used 0-15, then
I saw that all my midi related books and documents use 1-16 so I
changed it, but now I see that I don't like it...

I also note that the General Midi specification lists the sounds as
1 - Acoustic Grand ... 128 - Gunshot. So there's another argument for
being 1 based for program change.
And, getting back to the original topic of note
numbers there's this:
http://www.harmony-central.com/MIDI/Doc/table2.html
That table says it comes from the Midi Manufacturers association, but
it can't be right, can it? OK, note 60 is suposed to be middle C, aka
C4 (iff you chose that designation for middle C). But note 57, three
half steps down, is in the A column on line 3, which would mean you'd
call note 57 A3 while calling note 60 C4. Surely you normally switch
the octave number when going between G and A, right?!?
'nother words, trust that table about as far as you can spit, if that.

no, you switch octave numbers at C's.

Ran into this while verifying what you said:
http://www.music.vt.edu/musicdictionary/appendix/octaveregisters/octaveregi…
It gives different octave numbering systems. ALL of which switch at
C. The two midi systems it gives are Note 0 = C-2, and Note 0 = C0,
giving middle C options of C3 or C5, omitting entirely the possibility
that C4 is middle C.
Sounds to me like the old wonderful thing about standards, that you
have so many to choose from, is REALLY in play here.
Anyway, thanks for coorecting me, Luis!

Yes, I think this is the case.

and the Patch /

because I know my two synths (Roland and Ensoniq) agree with this.
I think I make that the default, with the option to switch to 0-15
if I ever have midi gear that displays it this way. Displaying names
instead of numbers would also be an option (i.e. XY-Synth Z-Synth)
Thank you for the very nice links you gave us.

Very nice graphic!
Thanks to all who joined in. I learned a lot, and decided that my app
will call 60=C4, since it seems to be the most common case.

Yes.
2) which note name corresponds to 0? C0? C-1?
I don't know note names, I'm a computer musician, however generally
midi note 69 is supposed to be 440Hz which is something with the
letter "a" in it, in whatever case.
I don't know, if this is in the Midi spec, but it's a convention that
is followed in at least Max, Pd, Csound and everything else I know.

Then it is A1 speaking in musical terms. The octaves above (freq*2)
would be A2,A3,A4 and the octaves down (freq/2) are a,A(, Kontra-A
?)...
I don't know the midi terms but they always irritated me as a
musician. And as a sound engineer I think in frequencies, not so much
in midi-notes...

A2 is 220Hz ( think toot toot !)
A1: 110, A3: 440 etc p
