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
\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"
\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.
