The Voyager Mac editor's OS update utility sends the sysex data to Midi Out port at a rate of 256 packets at a time. This number seemed to be adequate for most interfaces. We can try to increase or decrease this number to suit your interface or make it user defined so "time out" on MV receiving side does not occur. The MV OS system is protected by the checksum so the update failure is not fatal. If opdate fails then MV reboots and the "old" system is restored. We will make changes to the editor OS Update utility described above in the next update.

I use the 50 msec setting on the SysEx Librarian software here. This setting works well with all my synths and my rather basic Emagic mt4 MIDI interface.
The second parameter of the SysEx Librarian software preference is the time out for receiving SysEx data. this is not used on your problem at all. But I use the 1 sec value here.
What version of the SysEx Librarian software are you using?
I am on the newest version: 1.04
And it worked well with my Voyger on the Mac OS 10.3.4 to 10.3.6

Maybe download the OS files again to make sure the files ae not corrupted somehow.

Thanks, Qwave!

I'm running the same version of Sysex and think that the first setting might be the culprit.

I'll download fresh files and try again this afternoon mirroring your settings. Hopefully tomorrow will bring better news -- I'll post an update either way.

Your help is always appreciated!

Just wanted to thank everyone for their help -- especially Qwave for enduring all of my questions. Here's a description of what lead to the final fix. I'll be more than happy to clarify anything for those encountering similar problems. Happy Holidays to all --

I'm not 100% certain exactly what fixed it, but I suspect it involved turning off time-stamping for the Motu 828mkII. This is a feat in itself because that is not an option accessible by the Audio/Midi utility or any of the Motu-installed utilities. For some reason the properties section of the 828 under Audio/Midi is "locked" and cannot be edited.

Sooo...after becoming desperate last night -- still nothing was working -- I opened up the Audio editor the 828 came bundled with called AudioDesk and found some setting called Transmit Sync under the Studio menu. In there, the option for MIDI Time Clock was checked, so I disabled that. This should have been accessible outside of Audiodesk, which is what I suspect the soon-to-be-released 828 driver update might resolve. Either way I'm now running 2.5 and was able to load/unload AE presets and reload my settings without loss -- so I'm a happy Moogist once again. In review here are the settings that finally worked for future reference:

Sysex Librarian preferences:
Transmission pause = 60ms
Sysex Timeout = 1sec
Midi Out= "Midi Port" (created by Motu 828mkII)

OSX AudioMidi Utility settings:
Moog sysex ID=1
All Midi options unchecked (General Midi, Timestamp, etc)
In/Out connections made between Moog icon and Motu icon

Motu Firewire Console Settings:
clock source: Macintosh built-in

Audiodesk settings:
Under Studio/Transmit Sync/ choose "echo" instead of "Midi Timestamp"
-- Top two pulldown menu choices for sync options set to none
Under Studio/Receive Sync/ choose a port other than the one your using -- do not choose "any"

In this case, upon powering up my Voyager requested an operating system reinstall upon start-up, choosing "yes" led the the second tier of the receive update menu, choosing yes to confirm lead to a message erasing flash memory, and then the screen requesting Bank C. I transmitted the 2.5 C bank (sysex) and it was successful. I chose receive update again, confirmed yes, warned erasing flash memory, and it requested A bank -- transmitted 2.5 A bank (sysex) successfully. Chose receive update once more, confirmed yes, erased flash, it didn't request any back, said ready to receive banks A,B,C or D. I sent 2.5 B bank (sysex) and it was successful. I then reloaded my presents after choosing receive presets and sending the sysex file. Everything looked fine. Switched Voyager on/off , works like a charm.

Only reason I mentioned all of this is b/c immediately before doing the above, I chose "no" to the initial reinstall request and proceeded directly to the receive update menu, confirmed yes, erased Flash, but this time it requested Bank A first -- which I sent and received the "Sysex failed!!" message. So, if anyone encounters the same problem, make sure they choose yes on the reinstall request during power-up that requests the C bank first.

Again, the setup used was a Mac G4 running 10.3.5 and Sysex Librarian 1.04, and a Motu 828mkII running Audiodesk v. 2.02.

Ah, a happy ending just in time for the holiday guests
