Converting common time to 12/8

My questions starts after this Preamble
I have a score in common time at a slow tempo (quarter = 90).  It is a pop ballad from 40 or 50 years ago and has many triplet groupings, some of which are hard for an ensemble to sight read, an example being
!NoteWorthyComposerClip(2.751,Single)
|Bar
|Note|Dur:4th|Pos:0
|Note|Dur:4th|Pos:0
|Note|Dur:4th,Triplet=First|Pos:0
|Note|Dur:8th,Triplet=End|Pos:0
|Note|Dur:4th,Triplet=First|Pos:0
|Note|Dur:8th,Triplet=End|Pos:0^
|Bar
|Note|Dur:8th,Triplet=First|Pos:0
|Note|Dur:4th,Triplet=End|Pos:0
|Note|Dur:8th,Triplet=First|Pos:0|Opts:Stem=Down,Beam=First
|Note|Dur:8th,Triplet|Pos:0|Opts:Stem=Down,Beam
|Note|Dur:8th,Triplet=End|Pos:0|Opts:Stem=Down,Beam=End
|Note|Dur:4th,Triplet=First|Pos:0
|Note|Dur:8th,Triplet=End|Pos:0^
|Note|Dur:8th,Triplet=First|Pos:0|Opts:Stem=Down,Beam=First
|Note|Dur:8th,Triplet|Pos:0|Opts:Stem=Down,Beam
|Note|Dur:8th,Triplet=End|Pos:0|Opts:Stem=Down,Beam=End
|Bar
!NoteWorthyComposerClip-End

I've decided to rewrite the chart in 12 8 time to make it easier for the ensemble to play such phrases correctly the first time when sightreading the chart.

Converting eighth, quarter, half and whole notes is easy - just add an augmention dot. 

This is a bit more complicated
!NoteWorthyComposerClip(2.751,Single)
|Bar
|TimeSig|Signature:Common
|Note|Dur:4th,Triplet=First|Pos:0
|Note|Dur:4th,Triplet|Pos:0
|Note|Dur:4th,Triplet=End|Pos:0
|Note|Dur:4th,Triplet=First|Pos:0
|Note|Dur:8th,Triplet=End|Pos:0^
|Note|Dur:8th,Triplet=First|Pos:0|Opts:Stem=Up,Beam=First
|Note|Dur:8th,Triplet|Pos:0|Opts:Stem=Up,Beam
|Note|Dur:8th,Triplet=End|Pos:0|Opts:Stem=Up,Beam=End
|Bar
!NoteWorthyComposerClip-End
It becomes !NoteWorthyComposerClip(2.751,Single)
|Bar
|TimeSig|Signature:12/8
|Note|Dur:4th|Pos:0
|Note|Dur:4th|Pos:0
|Note|Dur:4th|Pos:0
|Note|Dur:4th|Pos:0
|Note|Dur:8th|Pos:0^
|Note|Dur:8th|Pos:0|Opts:Stem=Down,Beam=First
|Note|Dur:8th|Pos:0|Opts:Stem=Down,Beam
|Note|Dur:8th|Pos:0|Opts:Stem=Down,Beam=End
|Bar
!NoteWorthyComposerClip-End
or, for more clarity,
!NoteWorthyComposerClip(2.751,Single)
|Bar
|TimeSig|Signature:12/8
|Note|Dur:4th|Pos:0
|Note|Dur:8th|Pos:0^|Opts:Stem=Down,Beam=First
|Note|Dur:8th|Pos:0|Opts:Stem=Down,Beam=End
|Note|Dur:4th|Pos:0
|Note|Dur:4th|Pos:0
|Note|Dur:8th|Pos:0^
|Note|Dur:8th|Pos:0|Opts:Stem=Down,Beam=First
|Note|Dur:8th|Pos:0|Opts:Stem=Down,Beam
|Note|Dur:8th|Pos:0|Opts:Stem=Down,Beam=End
|Bar
!NoteWorthyComposerClip-End

My rationale for converting the time signature:  While the piece is only 38 bars long, but has 10 sets of triplet eighths, 8 sets of triplet quarters, 4 tripletized quarter-eighths, 2 or 3 tripletized eighth-quarters, and a few tripletized half-quarter note figures.  Many of the triplets are syncopated, either beginning with an inbound tie or ending with an outgoing tied note.

My question:
Several parts have this rhythm in common time:
!NoteWorthyComposerClip(2.751,Single)
|Bar
|TimeSig|Signature:Common
|Note|Dur:Half,Dotted|Pos:4
|Note|Dur:4th|Pos:4
|Bar
!NoteWorthyComposerClip-End
It is necessary in common time to notate the fourth beat separately because it begins a new glissando phrase, and will change pitch before the end of the bar.

Converting to 12 8 time, the bar becomes
!NoteWorthyComposerClip(2.751,Single)
|Bar
|TimeSig|Signature:12/8
|Note|Dur:Half,Dotted,Slur|Pos:4^|
|Note|Dur:4th,Dotted,Slur|Pos:4
|Note|Dur:4th,Dotted|Pos:4
|Bar
!NoteWorthyComposerClip-End

Is there a more efficient presentation of this bar's rhythm, so as to reduce the double curved arches (tie and slur) to just one arch?

Since the tenuto is on a tie destination, no one should see it as an accent.

Thanks, Rick, I agree with you but I'm not sure how that clip produced the tenuto. 

I copied sample A but pasted as sample B. 

In any event, my problem is sample A.  How can I do that with just the one curved line?

However, let me withdraw the question.  Simple outbound ties from the first and second notes achieve what I need.  No slur needed.

Sample A is yours; Sample B is mine. What goes in and out of the Clipboard is one of those great mysteries like how Windows decides what my "recent files" are  :)

Since you want everything converted to 12/8, just use the "Played (hidden) staff" option.

Sorry not to reply earlier, Warren, I just saw your message last night.

This qualifies as a "drats!"  Had I known about or remembered your Triplets page, I would have saved most of the ten hours I spent rewriting the score and parts. 

Your tool did in a second or two what took me forever to do manually.  Comparing the results I only found one thing I did (and would always do) differently. 

Original bar in common time:
!NoteWorthyComposerClip(2.751,Single)
|Note|Dur:4th,Triplet=First|Pos:3
|Note|Dur:4th,Triplet|Pos:#2
|Note|Dur:4th,Triplet=End|Pos:3
|Note|Dur:4th,Triplet=First|Pos:5
|Note|Dur:8th,Triplet=End|Pos:5^
|Note|Dur:8th,Triplet=First|Pos:5|Opts:Stem=Down,Beam=First
|Note|Dur:8th,Triplet|Pos:3|Opts:Stem=Down,Beam
|Note|Dur:8th,Triplet=End|Pos:5|Opts:Stem=Down,Beam=End
!NoteWorthyComposerClip-End

Your tool:
!NoteWorthyComposerClip(2.751,Single)
|Note|Dur:4th|Pos:3
|Note|Dur:4th|Pos:#2
|Note|Dur:4th|Pos:3
|Note|Dur:4th|Pos:5
|Note|Dur:8th|Pos:5^
|Note|Dur:8th|Pos:5|Opts:Stem=Down,Beam=First
|Note|Dur:8th|Pos:3|Opts:Stem=Down,Beam
|Note|Dur:8th|Pos:5|Opts:Stem=Down,Beam=End
!NoteWorthyComposerClip-End

My way:
!NoteWorthyComposerClip(2.751,Single)
|Note|Dur:4th|Pos:3
|Note|Dur:8th|Pos:#2^
|Note|Dur:8th|Pos:2
|Note|Dur:4th|Pos:3
|Note|Dur:4th|Pos:5
|Note|Dur:8th|Pos:5^
|Note|Dur:8th|Pos:5|Opts:Stem=Down,Beam=First
|Note|Dur:8th|Pos:3|Opts:Stem=Down,Beam
|Note|Dur:8th|Pos:5|Opts:Stem=Down,Beam=End
!NoteWorthyComposerClip-End

The reason for splitting the second quarter into eighths is to more clearly show the beat.

Thank you so much for writing the tool and making it available.  When I need to do this exercise again, I will know where to look.
