good one, Mathieu why is it that on this chart http://www.phys.unsw.edu.au/jw/notes.html 55 is G3, not G4?
Because I'm too lazy to do the [- 1] and I don't rely on my octave numbers being in sync with anyone else's.
MIDI's note number 0 is C in octave -1. It's not audible. MIDI has 10⅔ octaves, simply because for binary coding reasons they had 2*2*2*2*2*2*2 possibilities. There were already plenty of annoyingly-high notes in there, so they thought that they'd rather complement it with an unhearable octave. (!)
But Pd has no such restrictions and can use all sorts of impossible MIDI notes and lots of microtonal resolution between them... as long as you don't try to convert to real MIDI codes. Note number -120 is the C of octave -11, note number 666 is the F# of octave 54. Note number 69.0001 is one 1% of 1 cent above A4.
In _this_ mail I did subtract 1, to comply with the chart.
