M:S Track wrong octave

[roccster]

So the track is set to play note C5 (default I think), but it sends out C4 through midi?
I verified this with my Microkorg, and to my iPad.

Any thoughts on this?

Cheers!

strictly speaking it doesn’t send ‘C4’ it sends a number that is related to at least two references depending on teh manufacturer - so firstly check whether it’s sending the number you expect rather than judging based on references

see e.g. this old discussion here about deviations from expectation …

Note value off

i’m inclined to agree that the labelling is on the ‘high side’ - if i understand correctly, the midi spec stipulates A440 is note 69, middle C would be 60 then, by that ref - on the AFour when I play Midi note 60, i get C5 displayed … now a couple of standards exist for labelling but I think that may be higher still - my reckoning is that it is only labelling and they may adopt using that system for the following reason … The NOT param displays a range from C 0 to G 1 where G 1 in this case is …

Doesn’t the MIDI standard specify how note numbers translate to frequencies ? Feels to me like it ought to but I guess from what you’re saying it probably doesn’t.

It does, but @roccster is comparing note labels, not note numbers (0 to 127).

So I guess in that case, there must be no standard for note labels (C4, A0, etc) relate to frequencies … otherwise there wouldn’t be a problem I guess.

Sorry … I’m just trying to figure out how these discrepancies come about.

MIDI Octave and Note Numbering Standard

@bibenu

I’m just trying to figure out how these discrepancies come about.

The discrepancies come about because, while the MIDI specifications are unambiguous about note number (60 (decimal) is middle C), they give no definitive statement for how to label octaves.

Therefore note 60 has been labelled as C3, C4, or C5 by various manufacturers.

Elektron’s recent instruments try to present the note number as well as the note label in their user interfaces.

Thanks for all your input. Now I got that sorted out, not a bid deal for me but just wanted to get an explanation since I thought It might be a bug
As always, great help here in this forum.

Cheers!

Wow. I had no idea it was that messy.
