bach.mc2pc weird modulo behaviour

[pedrnun]

Hi,
It seems to me that something's not right with the modulo handling of bach.mc2pc...
Best,
Pedro

Beware: modulo and mc2pc do very different things.

bach.mc2pc always assume the octave being fixed: if you ask for a subdivision in 11 parts, that does NOT mean that each part will be a semitone (as per your [% 11]), but rather that you're dividing the octave in 11 equal parts, each with 109.0909... cents.

Which makes your results correct: 6000 is still middle C, thus pitch class 0, and 5500 is closest to 5455... which is pitch class -5=6 (mod 11).

Hope this makes sense,
d

Of course! My bad!

Although, in [bach.mc2pc]'s help file it says: The modulo is set in the right inlet, or as argument. Default is 12 (semitones).
