[MatheusMoura17]

expected:

ToneSequencer.OnNoteAttack.AddListener(HandleOnNoteAttack);
ToneSequencer.OnNoteRelease.AddListener(HandleOnNoteRelease);

void HandleOnNoteAttack(int  chanel,  ToneNote note){
 // logic here
}

void HandleOnNoteRelease(int  chanel,  ToneNote note){
 // logic here
}

ToneSynth.OnNoteAttack.AddListener(HandleOnNoteAttack);
ToneSynth.OnNoteRelease.AddListener(HandleOnNoteRelease);

void HandleOnNoteAttack(int  chanel,  ToneNote note){
 // logic here
}

void HandleOnNoteRelease(int  chanel,  ToneNote note){
 // logic here
}
