Hi Thomas,

Thanks for your answer. I can understand. These are work arrounds on 
work arrounds so the idea can be lost.

The new thread 
http://lilypond.1069038.n5.nabble.com/naturalize-pitches-td188666.html 
does give me additional info.
Maybe changing automatic the source code is a better idea.

Simply I want as simple as possible notation in Lilypond for the 
instrument Djembe. Which is standard not supported in Lilypond.
With help with this newsgroup I could do so and it displays (layout {}  
function) fine.

All custom notes are :
one = \drummode { dba4 do ds dbm dom dsm }

But when generating midi I can not hear them. I bought a Djembe 
soundfount from 
https://robntweber.wordpress.com/2007/04/01/finally-moving-on/  with 
Piano layout.

So I had to match these layout. To generated a correct midi Djembe sound 
I need :

onemidi = { g4 a b  fis gis ais   }

Transpose is not possible I understand from you.
So I have to change following table :

Custom drum note -> Piano note
dba -> g
do -> a
ds -> b
etc.

That could do it, but I could not see how I could enter my table into 
that function.
Could you give an example of two note's?

Different results for layout and midi.

Remark : this code can not be executed, because it requires the Djembe 
libary.
I am more then willing to share this with you (all) if desired, but I 
think this makes it more confusing at the moment.

one = \drummode { dba do ds r dbm dom dsm }

% layout
\score {
 \new DrumStaff  <<
      \override DrumStaff.StaffSymbol.line-count =  #3
      \set DrumStaff.drumStyleTable = #(alist->hash-table djembe)
      \new DrumVoice = voice { #one }
         \set Staff.instrumentName = #"Djembe"
       >>
  \layout {}
}


%midi
\score {
  <<
\new Staff {
  % Statement should be enabled
  %  \new Voice = voice { djembe_to_midi_conversion {#one} }
  % Statement is now required but should be disable
  \new Voice = voice { g4 a b r  fis gis ais r  }
}
  >>
  \midi{}
}

How to implement the "djembe_to_midi_conversion" function?

This what I had in mind. But maybe changing the source code is a much 
better idea.

WIth regards,

Bernard
