Lilyponders,
While trying to get the music from all staves in a piece to combine
for MIDI output, I found a tip in the archives to create a staff group
to combine the music parts, then a score section for print output,
then a separate score section for the MIDI, more or less as follows:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%% Create staff grouping for music:
fullScore = \new StaffGroup <<
\melody % flute
\righthand % electric grand
\lefthand % drawbar organ
\bass % electric bass (finger)
>>
%% Stock print output section . . .
\score { . . . }
%% And now output MIDI with unwrapped repeats:
\score{
\applymusic #unfold-repeats \fullScore
\midi{\tempo 4 = 100 }
}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Which works just great! However, the only part that has the desired
MIDI instrument setting is the last part (bass). The first parts are
all the default piano. Bummer.
After a bit of fumbling around, I hit on this change . . .
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%% Create staff grouping for music:
fullScore = \new StaffGroup <<
\new Staff << \melody \melody >> % flute
\new Staff << \righthand \righthand >> % electric grand
\new Staff << \lefthand \lefthand >> % drawbar organ
\new Staff << \bass \bass >> % electric bass (finger)
>>
etc . . .
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
. . . which worked beautifully! Every part is created, combined and
plays back with the desired instruments.
I've only started using Lilypond about 10 days ago, and I don't
read or write music that well (I'm a play-by-ear bass & guitarist).
I have a number of songs I want to transcribe properly (as well as
demo), and Lily is making the process remarkably painless. So in the
spirit of FOSS, I thought I should give back to the community.
Thanks all!
