/*=============================================================================
| Written by Rayerdyne (2019) to make midi file from custom music format used |
| in Azimuth, using parts of Azimuth's functionnalities.                      | 
|                                                                             |
| Do wathever you want with this part of the code, its only initial goal was  |
| to make music arrangement easier. The code is given without any warranty.   |
|                                                                             |
