* Called on note synthesis parameter change events. These are |
1903 |
|
* internal events caused by calling built-in real-time instrument |
1904 |
|
* script functions like change_vol(), change_pitch(), etc. |
1905 |
|
* |
1906 |
|
* This method performs two tasks: |
1907 |
|
* |
1908 |
|
* - It converts the event's relative values changes (Deltas) to |
1909 |
|
* the respective final new synthesis parameter value (AbsValue), |
1910 |
|
* for that particular moment of the event that is. |
1911 |
|
* |
1912 |
|
* - It moves the individual events to the Note's own event list |
1913 |
|
* (or actually to the event list of the MIDI key), so that |
1914 |
|
* voices can process those events sample accurately. |

1917 |

* @param itEvent - note synthesis parameter change event |
