I've used the Juno-G software with no problem, and also done it as described above. I guess it depends on where you want to be able to pull it from later. Or if you need the dump as part of a performance.
I've used the dump transferred over MIDI rather than pulled from disk in keyboards in the past, as it was faster, since the sequencer program would already be running. Also the Juno-G needs to have the MIDI connection stopped in order to use the librarian via the USB data connection (its either/or with the 'G') not sure how the 'D' handles that.
May be more reliable via the Juno software though, as there may be a checking system for anything corrupt, or may even keep to two copies in case of corruption; not sure if it has any benefits.


I do not work here, but the benefits are still awesome
