Re: Issue 1620 in lilypond: Midi overflow with instrument changes

Comment #7 on issue 1620 by address@hidden: Midi overflow with  
instrument changes
http://code.google.com/p/lilypond/issues/detail?id=1620

(Oops, the warning from 2.12.3 is a false alarm; LilyPond starts with  
channel 1 for actual sounds, so wrapping around to channel 0 does not hurt  
the sound output.)

The attached file has a flute on one staff, and a second staff changing  
quickly through 16 other sounds, one at a time, at zero volume.  We should  
hear two notes from the flute, with silence in between.

This example isolates the problem that we have lost a way to re-use a midi  
channel, as we would for instrument switches, which I am fairly confident  
is the root problem that bothered Haipeng.
