Hi,
I'm having a problem setting the MIDI tempo from within a function. When I
compile the file below, I get the error message:
GNU LilyPond 2.11.35
Processing `test.ly'
Parsing...
<string>:3:11: error: syntax error, unexpected SCM_TOKEN, expecting DIGIT or
UNSIGNED or DURATION_IDENTIFIER
\tempo
#lilyvartmpb = \lilyvartmpc
test.ly:26:0: error: errors found, ignoring music expression
\relative c'
It seems that lilypond is complaining that the parameter Duration is not a
number. I've tried various ways of getting around this, but it doesn't seem
to work. If I comment out the \tempo line, I get a music file (
http://www.nabble.com/file/p14336623/test.png test.png ) with the
appropriate tempo marking, but it has no effect on the MIDI tempo.
Any ideas?
Cheers,
Garry.
