I suspect that even this could lead to wrong results, if the byte/bites
that follows the missing byte/bites should make sense for the string.

Theoretical MIDI doesn't need to be 100% reliable for sysex data that
requires a checksum, but not all sysex data requires a checksum and
sometimes even a checksum doesn't correctly verify the data. I noticed
it, when I wrote an editor to manage DX7 sound banks in the 80s or 90s,
that even checksums sometimes could be "flexible".

For live usage active sensing and a panic button are very important ;),
especially if MIDI is used by a sequencer but one MIDI IO only. If
possible each MIDI channel should have it's individual IO ;). I'm not
talking about a thru box, I mean real IOs.
