A harmless MIDI message, perhaps there exists a NOP SysEx?
E.g. a reset command is *not* harmless.

Here are a few SysEx I gathered, looking for MIDI SysEx documentation
Proteus SoundEngine System Reset SysEx F0 18 04 00 23 F7
without knowing what they do:
F0 56 64 4F 6C F7
F0 7D 12 34 10 02 11 00 F7

Sure, however increased code coverage *has* benefits.  E.g. sometimes I use Valgrind.
