Hello Sebastian,
it seems to me like you would require more than 16 midi channels (which
normally correspond to the staves in your score) and midi doesn't
support more than 16. So the output which would have gone to channel #17
is actually put into channel #1 (and inherits its instrument, dynamics
etc. properties), #18 is redirected to #2 etc. (that's the modulo 16
part). So either, if this isn't a problem for you (because all staves
use the same midi instrument for example), just ignore the warning [1]
or try using an extra score for midi, which combines some of the staves
into voices of one staff, so you don't have more than 16 staves in total.
HTH, Simon
[1] or use the scheme function ly:expect-warning:
#(ly:expect-warning "MIDI channel wrapped around")
#(ly:expect-warning "remapping modulo 16")
(somehow this doesn't suppress all the warnings, but only the first one
of a kind; I'll ask about that in a separate mail)

Hi:
I'm using Lilypond 2.16.2 I get the above warning sometimes.
Is this a bug? Or am I doing something wrong? I can't detect the error,
and the midi seems OK.
