Cannot write to voices 2, 3, or 4

• May 21, 2021 - 08:51

Cannot create a drum groove with the base drum in a separate voice so as to appear with stem down. Changing the cursor voice to anything but 0 (i.e. voice 1) . Here is the code snippet:

eTempo = newElement(Element.TEMPO_TEXT);
eTempo.text = '\uECA5' + ' = ' + Math.round(60);
eTempo.visible = visible;
eCursor.add(eTempo);

eLineBreak = newElement (Element.LAYOUT_BREAK);
eLineBreak.layoutBreakType = LayoutBreak.LINE;

eCursor.setDuration(1,16);
for (lj=1;lj<3;lj++)
{
if (lj % 2 == 0)
{
eLineBreak.eScore = curScore;
eCursor.add (eLineBreak.clone ());
}

for (li=1;li&lt;17;li++)
{
 // voice 1 (=0) - upward stem
 eCursor.voice = 0;

 // HH stroke
 var lelNote = eCursor.addNote(42);

 if (li == 5 || li == 13) {lelNote = eCursor.addNote(38, true);}    // Snare

 // voice 2 (=1) for BD  !!!!!!!!!!!!!!!!!!!!
 eCursor.voice = 1;
 if (li == 1 || li == 3 || li == 9) 
 {
  lelNote = eCursor.addNote(35, true);      // BD 1
  // lelNote = eCursor.addNote(36, true);   // BD 2 - also doesn't work
 }
}

}

onRun: {
    var eCursor = curScore.newCursor();
    // top voice
    eCursor.setDuration(1,16);
    eCursor.rewind(0);
    eCursor.track = 0;
    for (var li=1; li<17; li++){
        eCursor.addNote(42);
        if (li == 5 || li == 13) {
            eCursor.addNote(38, true);
        }
    }
 
    // bottom voice
    eCursor.setDuration(1,8);
    eCursor.rewind(0);
    eCursor.track = 1;
    for (var li = 1; li < 9; li++) {
        if (li == 1 || li == 2 || li == 5) {
            eCursor.addNote(35);
        }
        else {
            eCursor.addRest();
        }
    }
}

Unfortunately setting the cursor track didn't work.

Thanks! Correction - It did work if I rewind(0) and then add in the base drum.
I have now separated out the algorithms for the first track and and the second track.

Or of you want to use only one loop, you can do this

for (var li=1; li<17; li++){
        eCursor.addNote(42);
        if (li == 5 || li == 13) {
            eCursor.addNote(38, true);
        }
 
        eCursor.prev();
        eCursor.track = 1;
        if (li == 1 || li == 3 || li == 9)
            eCursor.addNote(35);
        else
            eCursor.addRest();
        eCursor.track = 0;
    }
