Hi,

I am trying to create a procedure to create rehearsal midi files for each voice of a choir piece. In order to do that I need to be able to dynamically create \book blocks (one for each voice). Is that possible? I have tried to have a music function output it like:

rehearsalMidi =
#(define-music-function
  (parser location)
  ()   
    #{ \book { .. }  #})

but that gives me an error:

music function cannot return #<Book>

Is there some way to dynamically create book blocks?

Have you tried Frescobaldi's score wizard or template facilities? I use them frequently for your specific purpose, giving me voice tracks with the track voice highlighted and the others at a lower dynamic. I have also used the various MIDI properties such as pan position to isolate a voice on the left, e.g., with the remainder on the right.

Cheers,
Colin
