* The End Level remains until the key is released and played again. That is, at a value of 100, the sound remains.
However, the PMC Sound Generator's One-shot sounds do not remain even when set to 100.
* If the levels of two adjacent points are set to similar values, the time between these two points may prove to be
shorter than what is actually set, or even zero.
