NoteWorthy Composer Forum

I haven't touched my fiddle in quite a while and noticed I was getting intonation problems. One idea to work on that would be to play the note, then the note would play through NWC and midi and I could hear if my note was in tune.

This is the working part of my script, it determines half the duration of the note and creates a rest followed by the note with it:

function calculate(clip) {
  var i, saveDur, saveDurB, saveDurE;
  var lines = new Array(), result = new Array();  
  lines = clip.split("\r\n");

  for (i=0; i < lines.length; i++) {
      result=lines[i].match(/(.*Dur:)([^\|]*)(.*$)/);
	  if (result == null)
		  continue;  // No duration, didn't follow grace note.
	  if (lines[i].indexOf("Grace") > 0) {  // Found a grace note/chord
        continue;  }
	  if (lines[i].indexOf("Rest") > 0) {  // Found a rest, ignore
        continue;  }
	// shell.popUp(lines[i]);
	saveDur = result[2];
	//shell.popUp(saveDur);
	saveDur = saveDur.replace("32nd","64th");
	saveDur = saveDur.replace("16th","32nd");
	saveDur = saveDur.replace("8th","16th");
	saveDur = saveDur.replace("4th","8th");
	saveDur = saveDur.replace("Half","4th");
	saveDur = saveDur.replace("Whole","Half");
	shell.popUp(saveDur);
   // thisDur = getNoteLength(saveDur);
   	// shell.popUp(saveDur);
	// Code to manipulate durations goes here
	saveDurB = saveDur.replace("=End",""); // In case of triplets.
	saveDurE = saveDur.replace("=First",""); // In case of triplets.
	lines[i] = "|Rest|Dur:" + saveDurB + "\r\n" + result[1] + saveDurE + result[3];
    } 
  return lines;

So far, so good except it changes a 32nd note to a 68th note.
This was my test data:

Nice  :D. Word boundaries are always helpful.

(Incidentally, I created practice files of that type for a friend who wants to "sight-transpose" with her Bb trumpet. I used a simple AWK script to generate a random sequence of muted/visible + playing/invisible note pairs. Youtube example (https://youtu.be/eFr_boXwOu4)).

H.M.

I know very well the problem...  :(

Nice.
I've used youtube a few times for NWC transcriptions a few times such as Thais accompaniment (https://youtu.be/N0eoXG2jrWU).

I should have taken up guitar and I wouldn't have to fret with intonation.

The bug was that after replacing 32nd with 64th, it is (unfortunately) an exact match when 4th is replaced with 8th.

• It can be solved by making that set of statements use a case construct where a break would follow each replace and only one replace is ever done to the duration.
• The 32nd can be replaced by X which will be turned into 64th after the Whole note is addressed.
• Instead of looking for "4th", look for /^4th/. That search string, as a regular expression must start the string so it would ignore 64th.
