converter actually re-maps the samples as best it can. This is done using an
internal reference table. It also re-scales parameters when required.

"As best it can" assumes there's a compatible sample in the target synth, right?
But if there is, one could just examine the O5 sysex and copy the desired parts
into the appropriate parts of the O3 patch, no?

think there may be some structural difference in the sysex message format. If
they are the same, then a sysex header change may result in some useful patches,
but probably not very close to the originals due to sample mapping differences.

I thought all synths followed the same Sysex format (except perhaps Kurweil). I
know I've
successfully edited Proteus 2 sysex using a hex editor.
