[MML] Wrong octave on certain notes

[revilofr]

Hi
Here is the reference song (French song : "Sur le pont d'Avignon" BTW)

c4c4c4rd4d4d4re4r8f8g8r8c8r8c8r8d8r8<g4

c4c4c4rd4d4d4re4r8f8g8r8c8r8d8r8r8c2

if we play this with timbre.js we can notice than both "<b8" are played on the upper octave wherease it should be played on the lower one.

Am I doing something wrong?

I'am digging into it and I'll try to fix this (maybe a pull request) but that part of the code is really hard to get into ;).
A little help from you would be really appreciated

Regards,
Olivier.
