Re: tie & tag

[Gianmaria Lari]

I tried (again) with PushToTag with no success. And I don't understand why it doesn't work. Here it is the code:

\version "2.21.00"
\tagGroup #'(screenOut midiOut)
nc = {\tag #'midiOut   <c c'> \tag #'tieTag {} \tag #'screenOut c' }
myScore = {\pushToTag #'tieTag ~ \nc \nc}
\keepWithTag #'screenOut \myScore
\keepWithTag #'midiOut   \myScore

I thought that the previous code would be equivalent to

\keepWithTag #'screenOut \pushToTag #'tieTag ~  {\tag #'midiOut   <c c'> \tag #'tieTag {} \tag #'screenOut c' } {\tag #'midiOut   <c c'> \tag #'tieTag {} \tag #'screenOut c' } 

\keepWithTag #'midiOut \pushToTag #'tieTag ~  {\tag #'midiOut   <c c'> \tag #'tieTag {} \tag #'screenOut c' } {\tag #'midiOut   <c c'> \tag #'tieTag {} \tag #'screenOut c' } 

and then to:

{c' c'}

{<c c'>~<c c'>}

Where is my mistake?

Thank you, g.

Hello Aaron,

made some tests and I discovered where are the issues.

Here is our working code (just a bit simplified):

\version "2.21.0"

\tagGroup #'(screenOut midiOut)
nc = {\tag #'midiOut   <c c'> \tag #'screenOut c' }
myScore = {\nc << \nc <>~ >> \nc}
\keepWithTag #'screenOut \myScore
\keepWithTag #'midiOut   \myScore

It works as desired (by me). It generates two scores. I attached to this email.

Now two issues. 

1) The code stop to works if I remove the highlighted element from myScore = {\nc << \nc <>~ >> \nc}. Here it is the new code

 

\version "2.21.0"

\tagGroup #'(screenOut midiOut)

nc = {\tag #'midiOut   <c c'> \tag #'screenOut c' }

myScore = {<< \nc <>~ >> \nc}

\keepWithTag #'screenOut \myScore

\keepWithTag #'midiOut   \myScore

I think the issue is related to implicite voice creation but in this situation I have not a clear idea how to fix it. Any help?

2) The code doesn't work with articulate script, it generates a warning and the ties disappear (tried with version 2.21.0 and 2.19.83). Here it is the code that doesn't work:

\version "2.21.0"

\include "articulate.ly"

\tagGroup #'(screenOut midiOut)

nc = {\tag #'midiOut   <c c'> \tag #'screenOut c' }

myScore = {\nc {<< \nc <>~ >> \nc}}

\articulate \keepWithTag #'screenOut \myScore

\articulate \keepWithTag #'midiOut   \myScore

Is there anything we can do?

Thank you, g.
