Hello,
I have figured "it" out - Cakewalk expects Key Signature to be in Track 0 of a
Midi file and Lilypond puts it in whichever track has it in, which is much more
sensible. I realized this while compiling the cry for help below, so I've left
my workings out in the message, but that seems to be the long and short of it.
Thanks for everyone's support.
Best
Giles
Here is an example of my input/output:
I create this by reading output from MIDIDSM which disassembles MIDI files and
outputs text which I manipulate into the Lilypond code below.
I can't with certainty provide the original source file, but it is not part of
the workflow in question - it provided \key d\major \time 6/8
This is not the only way I get data into Lilypond - as previously mentioned, I
also import using Frescobaldi, but it's what happens on the way out, I am
trying to figure out.
When I run the snippet ......
\version "2.18.2"
\score {
{ \mark "Boore's Dance" \key d\major \time 6/8 a''4. g''4 d''8 g''8 e''4.
fis''4 a''4. fis''4 d''8 g''4 e''8 d''4. \bar ".." }
\layout { }
\midi { }
}
I get ....
[cid:82b004c6-1e2c-4107-8b76-af84dd4b4476]
.... and a .MID that looks like this when I open it in Cakewalk without any
further processing.
[cid:68c9f205-686b-4668-b485-006aaf8495cf]
Interestingly, my new installation (about a week old) on Windows 11, produces a
file showing the \mark as a marker in Cakewalk, but still without the Key Sig.
... and produces this when processed by MIDIDSM with the options to export
TIme/Key Sigs ticked ......
[cid:e9904548-372b-4782-9068-8348b490ab60]

|End of track|
Track #1 ******************************************
Time Event
1: 1: 0 |Key Sig | D Major |
|On Note | chan= 1 | pitch=A 4 | vol=90
4: 0 |(Off) Note | chan= 1 | pitch=a 4
followed by lots more Notes On/Off until
|End of track|
I just noticed this, because I ran David Wright's midi file through MIDIDSM and
the Key Sigs stand out because there's more than one.
So, Cakewalk expects Key Signatures in Track #0 and Lilypond doesn't put them
there and how data is brought into Lilypond won't change that.

End of Track
As you can see, the key signature is right with the content track (track
2) and right at the start.
You really need to figure out which part of your processing then loses
it.
