That'll be it. It doesn't like looping sysex, since it ends up in a 'bad
data' loop.

That's normal behaviour.
The sysex format doesn't have an 'end of file' message - each part and
pattern, and the FTS/bank data are sent as separate blocks. These can be
received in any number, and any order, so there is no end as such.
There are handshaking messages, so when I write the P3 memory manager
utility, it will confirm what's happening, and re-assure you that your
transfer was OK, as well as letting you move patterns between tracks and
banks, and replace individual patterns etc.

Cheers,
