Hmm, I have not touched OS 1.0 so not really sure what you can or can't do with it. The earliest OS I see on the Moog site is 1.5. If it were me, I would not worry about backing that OS 1.0 up. The procedures for doing this kinda stuff (backing up patches and upgrading your OS) is pretty simple really.
Generally, it goes like this:
1) Ensure MidiOX is installed (or whatever the equivalent is for MAC if you use a MAC).
2) Ensure MIDI cables are connected (easiest to have your Voyager connected directly to your computer; no other MIDI connections).
3) Configure MidiOX to
receive Sysex data if you are backing something up off of your Voyager -or- configure MidiOX to
send Sysex data* if you are updating the OS on the Voyager. For anything Sysex-related in MidiOX, I use the Sysex Pane by clicking View/Sysex and clicking the desired menu items; for example click file/send Sysex file to send a sysex file to the Voyager. The OS updates are sysex files btw.
4) Access the Voyager display panel by tapping the Master button and look for obvious items within. Such as
- 'Send System ROM' = Use that to back up the three OS Banks (banks A,B,C - these are completely different than your presets)**
- 'Send Boot System' = Use that to back up the data which boots the Voyager
- 'Send Preset(s) = Use to back up your presets
- 'Receive Update' = Use this to receive a Voyager OS update. Read the release notes included in the software update for more info.. The most important thing in updating your OS is to read the instructions included with each release carefully. I would suggest reading the installation instructions thoroughly at least 2 or 3 times before you actually attempt. It'll help you understand what's going on better.
You have to apply OS updates one at a time. If you are on OS 1.0 then first update to 1.5 and then 2.1. And finally, 2.5. Each time you complete an update, power off the Voyager and then power it back up to be sure the update really did take and to watch your system come up. You'll feel better if you do. You can check the version by watching the display panel as it boots or by using the menu system.
Like I said, I would not bother backing up OS 1.0... that's just me though. Proceed at your own risk! If you choose to not back up your OS then ignore menu options such as Send System ROM and Send Boot System. Once you do your first update, you'll be doing the ones afterwards very quickly and without being so nervous
* In the Sysex panel be sure to bump up the delay in millisecond for the data buffer or else you will likely have transfer failures (don't freak if this happens, just try again after bumping the values up).
** I bet OS 1.0 has only banks A and B, since OS 1.5 only has that.
