searching for succession of notes
Hello,
Can anyone help, please? Quite often I want to change parts of an nwc score which I've found on the www, where the person has used two dotted semiquavers and a semiquaver to represent a triplet, and I want to change it to a triplet.  Is there a quick way to search for a succession of notes such as this, maybe by using some sort of macro?
Thanks, in advance for any help.

If I were to want to do this, I would save the file as nwctxt, then use a text editor which supports regular expressions to do the find and replace.

Thanks Phil, I'll give it a try.  Never done this before so not quite sure about regular expressions.  Also, if and when I manage to make the changes, do I then save it with the nwc extension?

I haven't tested it, but this User Tool may help:
When NWC imports a MIDI file it does not faithfully represent triplets; correcting them manually is a tedious business so I have written a User Tool to do this.

For what its worth:
In the past I've used the 'tripletise' user tool,
available at:

http://nwc-scriptorium.org/nwc2scripts_trip.html

to correct NWC's import of triplets.
This can be quite tedious, especially if more than one voice is involved.

Nowadays, I would import the midi into
MuseScore (free) and export it as a *.xml (or *.mxl)
and import it into NWC using the Niversoft convertor.

My experience has been that both MuseScore  and
Notation Composer (NOT Free)
import *.midi MUCH better than NWC does.

This is a quick tool to fix midi triplets.  First save the file on your computer (remember the location).  Open NWC with the file you want to convert and do Alt/F8.  Choose New and pick a group and a name for it.  Browse for the file you saved.  In the command line insert "wscript " at the beginning of the line (note trailing space after wscript).  Now you can select Run.

/* Midi triplet conversion by Warren Porter "MidiTriplets.js"
   After downloading this file, when setting it up in NWC User Tools create this command line:
  
   wscript "'Browse can insert the path for you' \MidiTriplets.js"
  
   This can convert "midi triplets" (16th, dotted; 16th, dotted; 16th) into a set of 8th, triplets

  var thisDur, thisNote, durSplit;

  var lineLength3 = lines.length - 3;
  for (i=0; i < lineLength3; i++) {  
    if (/Dur:16th,Dotted/.test(lines[i]) && !/Dur2/.test(lines[i]) && /Dur:16th,Dotted/.test(lines[i+1]) && !/Dur2/.test(lines[i+1]) &&

  lines[i+1]= lines[i+1].replace("Dur:16th,Dotted","Dur:8th,Triplet");

Amazing!  Very many thanks, Warren, it worked a treat!  I must study your macro to try to understand how it works.
Thanks again for your help.

Sorry, thank, too, to Rick and Haymo, I read Warren's solution before I realised that you had also offered one.  Thanks for your help, too, this forum is so useful!

You're welcome.  That script was a modification of an existing script framework and has a number of variables that could be safely deleted.  I think the only ones it really needs are i, lines, and lineLength3 within the calculate function.  If it finds a specific pattern of durations on three consecutive notes/rests/chords, it replaces them on clipboard/nwctxt data like this:
Code: (nwc) [Select · Download]
!NoteWorthyComposerClip(2.5,Single)
|Rest|Dur:16th,Dotted
|Note|Dur:16th,Dotted|Pos:-2|Opts:Stem=Up,Beam=First
|Note|Dur:16th|Pos:-1|Opts:Stem=Up,Beam=End
|Note|Dur:16th,Dotted|Pos:0|Opts:Stem=Down,Beam=First
|Note|Dur:16th,Dotted|Pos:2|Opts:Stem=Down,Beam
|Note|Dur:16th|Pos:1|Opts:Stem=Down,Beam=End
|Note|Dur:16th,Dotted|Pos:1|Opts:Stem=Down,Beam=First
|Note|Dur:16th,Dotted|Pos:3|Opts:Stem=Down,Beam
|Note|Dur:16th|Pos:2|Opts:Stem=Down,Beam=End
