Re: Some Midi Output Problems

[grick]


 You can reduce the volume of the default piano in the same way, by
 setting 
 midiMinimumVolume and midiMaximumVolume in the piano staff. Note,
 though, 
 that these controls only take effect on encountering a dynamic mark,
 so be 
 sure you have a mark at the beginning of the piano notes.

There is no piano staff, only a chordmode section (something like this):
--
Accordi = \chordmode 
{
  \repeat unfold 60 {
f2:9+ bes2:7
  }

  \repeat unfold 2 {
f1
f1
ees1
ees1
  }
}
--
Nor \set Staff.midiXVolume nor \ppp on chords (like f1\ppp) works.

Just to know this chordmode section is included in the staff this way:
--
\score {
  \new StaffGroup 
  
\new ChordNames {
  \set chordChanges = ##t
  \Accordi
}
\new Staff  \WithChords \global \Tromba 
\new Staff  \WithChords \global \Alto 
\new Staff  \WithChords \global \Tenore 
\new Staff  \WithChords \global \Baritono 
  
  \layout { }
}
--   

 
 BTW, an easier way may be to simply use quieter dynamic marks on the
 music 
 of the instruments you want to reduce - these also affect the MIDI
 volume.

The Control MIDI dynamic marks are printed in the sheet (and, by the
way, i have to replace the real dynamics). I want to avoid this.

 
  To do this i use often staccato notes (a4-. a4-. a4-. a4-.).
 
  I expect my midi output sound like (a8 r8 a8 r8 a8 r8 a8 r8) but
 sadly it 
  does not interpret them at all and sound like a simple (a4 a4 a4
 a4).
 
  I can simple write (a8 r8) version everywhere but the sheet become
 really 
  difficult to read for the performers.
 
  Is there a way to avoid to mantain a double version of the sheets?
 (one 
  for the performers with a4-. version and one for the midi output
 with a8 
  r8 one?)
 
 Sorry, apart from using separate versions I don't know how to do this
 other 
 than by writing a Scheme procedure to add the staccato marks in the
 midi 
 \score block.

Can you point me to some docs about this Scheme procedures? Something
specific for lilypond i found a general intro on the guile site.

Some Midi Output Problems

[grick]

Hi people,

first of all, I would like to thank lilypond developers for putting in 
so much time and effort into this beautiful software. All your hard work 
is greatly appreciated.


And now, i explain my problems. I'm using lilypond-2.10.33 on a Ubuntu 
8.04 (with no GUI interface but gvim, xpdf, timidity, some makefiles and 
scripts ) to create the sheets for the brass section of my band 
(trumpet, alto, tenor and baritone sax plus chords).


Midi Trumpet Volume
---
The trumpet sound included with timidity is too soft. It's nearly 
inaudible between the saxophones sound (ironically, the real trumpet 
sound cover all the sax :) ).


Luckily i recently read in the docs the lilypond instructions to control 
the midi volume range of an instrument.


So i include in all sax sheet these lines, to half the volume of the 
saxophones and mantain some range for dynamics:


\set Staff.midiMinimumVolume = #0.2
\set Staff.midiMaximumVolume = #0.5

In this way the trumpet sound is audible. But it's not enough. Now the 
chords played by the acoustic piano(default) in the background is too 
loud and cover the instrument armony in most passages.


The question is: how i can decrease the chords volume? (or the opposite, 
how can i increase the trumpet volume instead of lower all the others 
instrument?)

Staccato

I want to create midi files that sound exactly how the performers have 
to play the sheet.


To do this i use often staccato notes (a4-. a4-. a4-. a4-.).

I expect my midi output sound like (a8 r8 a8 r8 a8 r8 a8 r8) but sadly 
it does not interpret them at all and sound like a simple (a4 a4 a4 a4).


I can simple write (a8 r8) version everywhere but the sheet become 
really difficult to read for the performers.


Is there a way to avoid to mantain a double version of the sheets? (one 
for the performers with a4-. version and one for the midi output with a8 
r8 one?)

Thank you in advance for the answers!
