Error Message

[Mark Stephen Mrotek]

Hello:

 

The following error message is appearing in the output log:

 

warning: cannot find property type-check for `TupletSpannerDuration' (translation-type?).  perhaps a typing error?

warning: doing assignment anyway

 

Since I copied the following

 

\set TupletSpannerDuration = #(ly:make-moment 1 4)

 

from the manual and pasted it into the code, I am not sure what the error is.

 

Thank you for your kind attention.
