Call me slow. I've only just discovered View | Viewer Preview which seems to give you a preview pane of what it would look like using the viewer. That's probably pretty cool. And it positions the view at your insert-point, which is very handy. Anyone else notice this?
Here's an NWC patch for the Goldstar MIDI ART GS100R (midi box) Bank 1. Download the zipped ntwpatch.ini file (7K) that includes this patch and others. You can replace your ntwpatch.ini file with this file or cut and paste the info you need.
Further to printing trills. This same method of Insert: Text can be used for turns and mordents. In this case, improvise the symbols with tilde "~" or some slashes "//" Remember to set the text to bold and turn off Preserve Width under the Expression Placement tab of Insert: Text.
For arpeggiating chords (you know, that little squiggly symbol in front of a chord, meaning "ripple up"):
Go to sixty-fourth notes.
Run the chord up in a run of individual notes, and bar them together to make them look neater. If you have three or six notes, you may want to tripletize them to make them a little faster. If you have five notes, you could tripletize just the first three.
Work out how much time you have left in the chord and enter the chord using notes of that length. This will probably require dotting and maybe even double dotting or (rarely) tying of two individual chords to get the right note length.
Tie (using the "/" key) each arpeggio note to its corresponding chord member.
Press F9 to implement all the ties.
Press F5 and be amazed!
This works well, though if you are using very fast tempi you may wish to increase the note length of your "arpeggiators." Download the file arpeggio.nwc (1K) to see an example.
If you want both the Trill Sound (achieved through manual scoring at this stage), but also a score that prints without the notes, but a TR. above the note:
Add the tr. (or tr~~~) using Insert: Text, placing it where you would like it to go
Create a new stave with the appropriate time and key sigs and fill with empty bars (use whole rests) up to the bar you need the trill
Add the appropriate notes to do the trill
When printing, simply exclude the new staff
The only trills that this won't work too well on are those that "borrow time" from the main note, and don't start with that note (e.g. D C B C, as opposed to, say C D C B C). This is because the main note (C in this case, which will be in the original staff) will sound at the same time as the first auxiliary note (D in the first case, and a nice unison C in the second case). This makes much more sense having tried it out.
