We're getting there, Bob.
The Juno-D needs a USB/MIDI interface to hook up to a PC, unlike the G I believe. (*)

I'm just waiting on Roland support to get back to me to guide me through the use of 'Librarian' (the 'on-line' manual is difficult to follow).

The purpose of these procedures from my point of view is backup and syncing my two machines so that they are identical. I have one that will now stay hooked up to my studio, while the other goes out to rehearsals & gigs.

In fact there now appear to be no fewer than four ways of effecting these backups:
- In Librarian, using the .jul file format
- In Librarian, using SMF
- In PTPA via the SysEx window
- In PTPA, by 'recording' the SysEx data in a track, as you describe.

(*) BTW, I just bought and installed one of these - the MIDISPORT UNO (M Audio).
I ran into a small problem which was easily dealt with by M-Audio customer support. Although my PC was happy to install the device's drivers from the maker's disc, it preferred to use Windows' own "class compliant" drivers when it saw that the device was plugged in.
Result: neither PG Music nor Roland's software was 'seeing' the interface. As a remedy, we 'forced' Windows to use the M-Audio drivers.
