Thanks, David. This works a lot easier.

Re: Midi Instrument: change?
David and Jerry,
I've been using the "method" shown on that Lilypond doc page for years.
I confirm that it does work for me. I can put
\set midiInstrument = #""
anywhere in a voice and LP will change the midi instrument. Which is why
I suggested it to Jerry.
But there is no denying that David (of all people) certainly knows
whereof he speaks. The example code he provided does exactly the same
thing, without needing to modify the \staff and \voice contexts. It has
the advantage that it's much easier to code (imagine that!)
JH - A working code example for you is David's code
%%%CODE
\version "2.20.0"
\language "English"
\score {
\new Staff \with { midiInstrument = "violin" }
{ c'' c'' c'' c''
\set Staff.midiInstrument = "pizzicato strings"
c'' c'' c'' c''
\set Staff.midiInstrument = "violin"
c'' c'' c'' c''
}
\midi {}
}
%%%CODE

The docs referring to per-voice/per-staff channel mapping have no
relation to changing the midi instrument temporarily and they don't
state anything like that either.

Just following the docs (per the link provided). Should the docs be updated?

Frankly, I have no idea what you all are talking about.
\score {
\new Staff \with { midiInstrument = "violin" }
{ c'' c'' c'' c''
\set Staff.midiInstrument = "pizzicato strings"
c'' c'' c'' c''
\set Staff.midiInstrument = "violin"
c'' c'' c'' c''
}
\midi {}
}
Works fine without moving the Staff_performer.

1. Midi Instrument: change? (JxStarks)
2. Re: Midi Instrument: change? (Guy Stalnaker)
GuyS
I too wanted to know how to do this. Since I have limited experience
with the latest versions of lilypond due to total confusion of the new
syntax's. I did find this example you linked to and provided, before
this question came to the newsletter.. However without a minimal
example (which I did not find so if it's available somewhere a link
would be fine). So I'm pathetic but I could not see how this works.
J
See
http://lilypond.org/doc/v2.19/Documentation/notation/midi-channel-mapping
Where the method is shown. Basically, you put the instrument into the
Voice context:
%%% Code
\midi {
\context {
\Staff
\remove "Staff_performer"
}
\context {
\Voice
\consists "Staff_performer"
}
%%% Code
You'll see how it works. I do this all the time.

GuyS

This is particularly useful for strings voices which do occasional
pizzicato sections. It seems awfully cumbersome to write a whole part
just for 5 or 6 measures of pizzicato. How would the change (and the
change back) be coded?
Thanks in advance,

Midi Instrument: change?
Hi all, Is it possible to change the midi-instrument in the middle of a part? This is particularly useful for strings voices which do occasional pizzicato sections. It seems awfully cumbersome to write a whole part just for 5 or 6 measures of pizzicato. How would the change (and the change back) be coded? Thanks in advance, Jerry
