Re: produce midi drums but hide staff

That would mean Id have to write out the pitch notes (ie new staff) twice?
once for the layout and then again with the drums for the  midi.

Of course not:

melody = \relative c' {  c4 d e f }

\score {
 <<
 \new Staff { \melody }
 >>
 \layout { }
} 

\score {
 <<
 \new Staff { \melody }
 \new DrumStaff...
 >>
 \midi { }
} 

HTH.
