Re: how to get expression in midi

[Dario Marrini]

thanks to all, I tried the Teoh's solution and it worked in a few seconds... 

now, other questions... 

• violin part has many 1/8 notes, many are repeating itselves, listening the MIDI output it seems it's not very well, notes' sounds are too much closing, and repeating notes sound like a unique sound almost. how may I fix this? I think it'd better writing each 1/8 note as 'staccato', but may the Midi output will be according on that? besides, it's very hard now to rewrite all the code, so, there is some tool to do that, a sort of 'mass modifier' about the text code? I dont' want to fight with my poor Perl knowledge,,,,
• is it possible to change the velocity (volume?) of a single long note? example, brass ensemble start with a 'sf', then play crescendo the same note while 'crescendo' from a 'p' to a 'f' again; I don't know if it is possible in a MIDI environment, and how to perform this using lilypond notation

thanks to all

How about:

\score {
  \new Staff<<
      \new Voice
        { c''4 c'' }
      \new Voice { s4\pppp s\ffff }
  >>
  \midi {
        \context {
              \Staff
              \consists Dynamic_performer
        }
        \context {
              \Voice
              \remove Dynamic_performer
        }
  }
}
