Nah - they're fixed length in this case.

Thanks for that. I'll bear it in mind but, as I sort of mentioned, for
this synth and for the purposes I want it it looks like the data is a
fixed length, and they're all terminated with EOX anyway.

That is unless (as I hope is NOT the case) any other MIDI data is
interspersed with the SysEx messages. I would hope not but you never
know. Guess it depends on a number of things.
