Comment #14 on issue 4539 by address@hidden: Set the sequence name  
in MIDI using title information from \header block

> Why would you default to an empty string rather than "control track" here?

Since the purpose of this change is to give a name for the MIDI sequence  
using the information from a \header block, I just thought that the  
name "control track" would be a very odd default name for a MIDI sequence  
if no suitable \header block from which to query the name is found.  If  
there's no name given for a MIDI sequence in the input file, I wouldn't  
like the application to invent one for me (especially a "technical" name  
such as "control track").  Would some other default than the empty string  
(such as "unnamed") work better?

I guess that the point of the request for this enhancement is that the  
string stored as the name of the first track in the MIDI file may get  
displayed in some form to the user by various MIDI synthesizers (and it  
wasn't possible to change the name from within the input file) – for  
example, timidity 2.13.2 outputs the following information when it starts  
to play a MIDI file created using LilyPond 2.18.2:

...
Playing A.midi
MIDI file: A.midi
Format: 1  Tracks: 2  Divisions: 384
Sequence: control track
Text: creator:
Text: GNU LilyPond 2.18.2
...

Note the "Sequence: control track" line, which displays the name of the  
MIDI sequence.  (The "Text:" lines come from additional text events that  
get always stored into the first track of the file by the  
Control_track_performer.)

Another example that I've seen is a digital MIDI piano which, when given a  
disk with LilyPond-generated MIDI files in it, will display (in a small LCD  
panel) the contents of the disk for selection not as file names, but as the  
sequence names stored in the MIDI files on the disk.  The result was a list  
of MIDI sequences all called "control track", making the selection of the  
file quite difficult...
