Hi Dirk,

the problem is that this is probably non-trivial:

MIDI has something that is called "running-status" where some commands
are abbreviated by ommiting the first octet if that is the same in
the consecutive commands.

I really don't know how I could do the MIDI-dissection without knowing
where the actual Status-Byte comes from (in RTP-MIDI each packet still
contains a "phantom" running-status at the beginning of the command
section).  This might not be the case for all ip-based MIDI-protocols...
